The world used to be a very different place. When accidents happened away from home, victims had no way of calling for help. If a driver broke down on the road, he or she would have to either go to a stranger's house to use the phone, or wait for a good Samaritan to stop and offer assistance. Thanks to cell phones, it's now easier than ever to stay in touch, and stay safe.
This is not to say that cell phone users don't have emergencies. They constantly face the danger of running out of batteries. While this may seem fairly unimportant, a dead cell phone is of no use when your care breaks down. And it can certainly be a problem if the cell phone battery dies in the middle of an important conversation.
There are differences in the types of cellular phone batteries, and in the phones that use them. An analog phone, for instance, will typically go through batteries faster than digital models.
Capacity
It is possible to buy high capacity cell phone batteries that provide more talk time and stand by time between calls. High capacity batteries do weigh a little more, so they might not be the best choice for those wanting a featherweight cell phone.
Value
You can now buy cell phones for a fraction of what they used to cost, but they can still involve a sizeable investment. You might have to save up to buy the cell phone you want, and you will need to budget your monthly income to accommodate the user fees and call charges. Another expense that should be considered is the cost of better cell phone batteries. Most phones come with a basic battery, but you might want to upgrade to a higher capacity. So, as with any purchase, the cell phone battery that costs less may not be the best quality options. Basically, you get what you're paying for. If you find a high-capacity battery at a super-low price, make sure it's not restored rather than brand new. Restored cellular phone batteries are usually made with old components, and don't work as well as new ones. If you're offered a battery at an incredibly cheap price, it's probably restored.
Warranty
Cell phone batteries do not come cheap, so you need to be sure that your investment is protected. A warranty is important because, like any manufactured product, some cellular phone batteries may not work properly, or last as long as expected. If your battery fails to meet the manufacturer's promise within the specified amount of time, they will usually offer a new battery in place of the faulty one.
Here are a few tips to help ensure that your cell phone and battery enjoy a long and happy life together:
1. When charging your battery for the first time, be sure to follow the manufacturer's instructions carefully.
2. If you have to remove the battery from your phone, make sure that it doesn't come in contact with metal objects such as keys or pocket change. This can keep the battery from working properly.
3. Cell phone batteries are prone to damage from extreme temperatures. Don't leave your phone in the car, or anywhere it will be exposed to excessively hot or cold temperatures.
4. Try not to drop your cell phone. Dropping your phone, especially on a hard surface, can irreversibly damage the phone and the cell phone battery.
5. Different phones, and cell phone batteries, need different chargers. Make sure that you're buying the right charger.
6. Your cell phone will most likely last you a year or two, or even more. Don't skimp on quality; choose a cell phone that will meet your needs now, and has the lasting reliability you need to keep you talking for years to come.
7. You can get more life from your cell phone, even when you're done using it. There are many community services, such as women's shelters, that will happily accept your cell phone donation. Think of other ways that you can reuse or recycle your cell phone and accessories.
Cell phone batteries can sometimes set you back as much as an entire new phone will cost. For this reason, you need to extend the life of your battery as much as possible. If you do find yourself in the position of buying a new battery, make sure you get the one that offers best performance and a solid warranty.

Cell phones run on various kinds of batteries depending on the manufacturer, phone size or shape and features. There are basically four types of cell phone batteries: Lithium Polymer, Lithium Ion, Nickel Metal Hydride and Nickel Cadmium.
Lithium Polymer is the most recent type and applies the latest technology in DC power. This type of battery is light in weight and will not explode even if pierced. The battery elements are enclosed in plastic pouches and do not have memory defects. They last about 50 times longer than Nickel Metal Hydride batteries.
Lithium Ion is also memory efficient and longer lasting than Nickel Metal Hydride batteries but they are quite lighter. They tend to be expensive and would only fit new models of phones. Most Lithium-ion batteries apply a fast charge technique to quickly charge up your cell phone up to 80% capacity and then slowly bring it up to full power in about two hours. Nickel Metal Hydride is also memory efficient and lasts longer than the NIM type about 40 times.
This type of battery is good for people who need rapid charging and if used with a car charger can be fully charged under 1 hour. The special formula permits the concentration of energy in a single pack – sometimes about twice the power of Nickel Cadmium. This type is preferred by a lot of mobile phone users because it lasts long and is cheap. Again, they are non-toxic and appeals to environmentalists. Nickel Cadmium is the oldest type and has a lot of memory defects. Another severe disadvantage is that they will have to be totally discharged before you can charge them again otherwise you may irreversibly damage them. Again this type is highly toxic due to the presence of Nickel Cadmium and is gradually being phased out by cell phone manufacturers.

These days, given the tremendous amount of waste that is generated every single day, more and more emphasis is given towards recycling. Organizations and even governments all around the world are calling for the efficient implementation of recycling measures especially since research has shown that the earth’s natural resources are fast depleting because of the continuous presence of toxic and unreusable items. Some of these items include computers, batteries and cellular phones, which have become staples in almost every home and office. One can just imagine the millions of tons of waste should these pieces of equipment be allowed to rot. Minerals found on earth are unrenewable resources and should these be used up and depleted due to the presence of tiny yet deadly particles, all of us will suffer.
Hence, everyone is encouraged to learn the importance of recycling computers and batteries and cellular phones.
Computers, for one, have tiny, bioaccumulative compound particles that could pose harm not only to animals and to bodies of water, but to humans as well. Batteries, on the other hand, contain cadmium, lead and mercury. If batteries are carelessly thrown out, they can end up in incinerators and landfills. The earth’s surface may seep the toxic ingredients of batteries and this may lead to soil and water contamination.
Meanwhile, cellular phones have become indispensable gadgets. In fact, the number of cell phone subscribers is anticipated to grow by the billions every year. However, while some consumers store old phones and look for outlets where they can have cell phone recycled, many include these old ones in their household garbage, prompting highly poisonous elements such as mercury and lead found in each cell phone unit to be released. It is important to keep these elements away from landfills so as to maintain the health of the soil and of the animals that depend on the earth for food.
There are many resources available to help recycle computers, batteries and cell phones. For one, there are organizations that take in these old items via drop off centers or home pick-up scheme. These organizations either refurbish the items and donate them to financially hard up communities or forward them to a recycling facility for proper disposal.
You can also contact the manufacturers of these items and ask if they have a recycling program. Companies that have recycling programs even offer free pick up of your old computers, batteries and cell phones.

While technology has grown it would seem as if cell phone batteries have not. It may not be so much that batteries are getting worse more so than cell phone applications have grown to enormous proportions. The way we use cell phones has grown tremendously through time through the additions of cameras, games, web browsing, and the list continues to grow. Following some of the tips below should help you manage your battery life better. It will take some sacrifices, but if you want a longer lasting phone it may be worth it to you.
1. Key Pads - Turn off the pad tones for dialing. Yes they do offer some reassurance that each key has been pushed, but in reality it is unnecessary . Living without this extra luxury can save you some extra battery life, and you really aren't going to suffer for it. Go to your cell phone's menu and turn them off.
2. Vibrating Ringer - While some public functions may require the stealth of vibration, you really shouldn't have vibration on along with ringtone. The cost to your power source is only going to drain you cell phone battery faster. Try just turning up the volume of the ringer one notch.
3. Bluetooth - When not in use, bluetooth can drain battery life substantially. Turn it off when not in use, otherwise it's a constant application tapping into your phone battery.
4. Display Panel - Lower the brightness of your display panel as well as the light time of the phone. I think this is self explanatory. Light takes energy, energy is your battery. You might not want to lower it too much though, your eyes may strain too much. Adjust it to a suitable level for easy reading, but don't make a flashlight of the thing. Same goes for the light timer, make sure it allows enough time to see what you need to see without losing your patience and having to push a button every second to keep reading a number.
5. Phone Games – The number one killer of cell phones would have to be games. Maybe you could wait till you got home to play on your play station or PC before indulging in battles and puzzles. While great time killers, they're battery killers.
6. Text Messaging - Texting is a great non intrusive way to communicate but if your fooling around chatting all day your wasting your battery. If texting during the day, make sure your lighting display is set super low to kind of balance out the battery usage.

It’s hard to imagine what the world did before the use of cell phones! We have become so dependent on having a cell phone that we tend to panic if we forget it at home or if the battery dies. Cell phones are an important part of most everyone’s life that allows them to be reachable 24/7 for family, friends and business associates to contact them.
When considering a new cell phone purchase it is also important to consider the cell phone batteries. You probably don’t even think about it but do you know that your cell phone battery is the most important part of your wireless phone. Without the cellular phone battery, the cell phone does not work.

Choosing your own cell phone plan You already have your very own cell phone. Now you need to choose the cell phone plan that is the best for you. Choosing your cell phone plan is like choosing your activity for your cell phone. The manner of choosing your cell phone plan depends on how you expect to use your cell phone. Whether itâ€TMs for business or just for ordinary communication, you must choose the cell phone plan best for you. Cell phone plan usually has a set of numbers called peak minute and an unlimited number of off-peak minutes. Peak minutes are usually sold in blocks and this is mainly the main feature of cell phone plan options of the different providers. Most cell phone plans has a free mobile-to-mobile minutes, which means you can avail of free call to others with the same cell phone plan providers with you. Keep in mind that the exact start and end times for peak minutes varies from provider to provider. If you think your usage falls somewhere in between two cell phone plan blocks, think wisely and pick the plan with more minutes, because overtime minutes are more expensive and can add a large sum to your cell phone bill. If youâ€TMre the type of user that uses cell phone only on evenings and weekends, then you should avail of the cell phone plan called off-peak or also known as “night and weekendâ€� minutes. Some cell phone service providers have a long-distance free call. So if you have relatives in far places, better avail this cell phone plan so that youâ€TMll not anymore use your landline in calling them. If you want to avail this plan, make sure that it includes enough off-peak minutes for your talk time or else youâ€TMll be paying overcharges, which makes the free long-distance calls useless. If youâ€TMre always on the go and like to travel, you must avail of cell phone plans which offer wide range of roaming areas. Roaming areas are areas outside the cell phone providerâ€TMs coverage area. If youâ€TMre outside the providerâ€TMs area, it does not mean that your not have the providerâ€TMs services. Itâ€TMs just that other providers in the area will handle your call. Usually, calls made from roaming services are much expensive that ordinary calls. So, try to look for cell phone plans with wide range of roaming service. A family or shared cell phone plan may be a good option for you. This cell phone plan can cause you less each person in the family. All you have to do is visit the website of the service provider and look for the option for "family plan" or "get 2 phones" that appears on most cell phone offer pages. For cell phone users who plan to use their phones only in emergencies, or those who don't want to undergo the cell phone provider's credit check, a prepaid cellular plan can be a good option as well. However, both the cell phones and the per-minute costs are lower with a service contract of one or more years. There is a wide range of cell phone plans. All you have to do is choose the right plan for you. Itâ€TMs better to study first the different cell phone plans of different cell phone providers to have the best cell phone plan or you.

A battery consists of a cathode, an anode and an electrolyte. The cathode is a metal oxide strip, the anode a metal strip that has a tendency to oxidize, and the electrolyte a conducting medium in which the anode and cathode are kept. When the anode and cathode are connected, the anode draws oxygen atoms thus generating electricity. Various types of batteries are available like alkaline batteries, lead acid batteries, lithium/manganese dioxide batteries, nickel metal hydride batteries (NiMH), Nickel cadmium (NiCd) batteries, lithium ion batteries etc. For mobile phones lithium ion (Li-Ion) batteries are predominantly used.
Lithium ion cell phone batteries are rechargeable batteries. They are much lighter than other batteries because they carry extremely high-density charges and are easier to store than NiMH batteries. They do not suffer from memory effect. Sony Corporation first introduced lithium ion batteries in 1991.
Memory effect is a strange phenomenon - if a battery (usually nickel batteries) is repeatedly charged at partial discharge, the battery "forgets" that it has the capacity to discharge fully. Gradually the battery loses all capacity to fully recharge and has to be discarded. Li-Ion batteries also have a low self-discharge rate of approximately 5% compared to other batteries that are generally around 20-30%. However if mistreated Li-Ion batteries can be dangerous and have very short lives.
Some guidelines that can increase cell phone battery life are:
* Never discharge Li-Ion battery fully, recharge it at 40% capacity.
* Never store batteries above 60 deg Celsius.
* Do not keep batteries in moist places.
* Do not dispose off batteries in fire. They may catch fire or explode.
* Store in a cool places, this will increase their life considerably.
One of the disadvantages of Li-Ion cellular phone batteries is that they have a fixed shelf life of approximately 5 years. The capacity of the battery reduces about 20% every year. Hence it is a good idea to check the manufacture date on cell phone batteries before purchasing. Generally in cell phones, the batteries cannot be interchanged and cellular phone batteries are model specific.

 While technology has grown it would seem as if cell phone batteries have not. It may not be so much that batteries are getting worse more so than cell phone applications have grown to enormous proportions. The way we use cell phones has grown tremendously through time through the additions of cameras, games, web browsing, and the list continues to grow. Following some of the tips below should help you manage your battery life better. It will take some sacrifices, but if you want a longer lasting phone it may be worth it to you.
1. Key Pads - Turn off the pad tones for dialing. Yes they do offer some reassurance that each key has been pushed, but in reality it is unnecessary . Living without this extra luxury can save you some extra battery life, and you really aren't going to suffer for it. Go to your cell phone's menu and turn them off.
2. Vibrating Ringer - While some public functions may require the stealth of vibration, you really shouldn't have vibration on along with ringtone. The cost to your power source is only going to drain you cell phone battery faster. Try just turning up the volume of the ringer one notch.
3. Bluetooth - When not in use, bluetooth can drain battery life substantially. Turn it off when not in use, otherwise it's a constant application tapping into your phone battery.
4. Display Panel - Lower the brightness of your display panel as well as the light time of the phone. I think this is self explanatory. Light takes energy, energy is your battery. You might not want to lower it too much though, your eyes may strain too much. Adjust it to a suitable level for easy reading, but don't make a flashlight of the thing. Same goes for the light timer, make sure it allows enough time to see what you need to see without losing your patience and having to push a button every second to keep reading a number.
5. Phone Games – The number one killer of cell phones would have to be games. Maybe you could wait till you got home to play on your play station or PC before indulging in battles and puzzles. While great time killers, they're battery killers.
6. Text Messaging - Texting is a great non intrusive way to communicate but if your fooling around chatting all day your wasting your battery. If texting during the day, make sure your lighting display is set super low to kind of balance out the battery usage.

The cell phone industry has come a long way since the inception of the private use personal cellular phone. In the late eighties and very early nineties it was a huge deal if you had a corded cellular phone in your car. The personal cell phone had terrible reception and was so large that you couldn’t exactly put it your pocket for convenient usage. To look back now and compare the cell phone industry’s first amazing wonders with the sleek razor phones of today, the first cell phones were actually laughable, but of course we didn’t know it.
Cell phones operate on a basic frequency notion of cell sites and the use of handover to be competitive in the industry. Using technology that most people aren’t interested in provided it is working when they are using their cell phone, handover is at the heart of the cell phone competition craze to provide the network with “fewest dropped calls.”
While cell phone technology and even some cell phone usage has been around since the mid nineteen forties, most people hadn’t heard of the usefulness of a cell phone until the early to mid eighties, where cell phones were predominately car phones.
Cell phone technology has grown immensely since cell phone usage has hit a massive boom stemming from the late nineties to early two thousands that has increased the capability of the average cell phone. Cell phones were once upon a time utilized only for placing or receiving a phone call. Now they come with the ability to text and instant message, take pictures and videos, do math, download information and music from the internet, wake you up with their plethora of alarms, download e-mail, and perhaps in the next year or two they will be able to walk to the dog and do the dishes. Cell phone technology is advancing at an amazing rate in an attempt to annihilate cell phone competitors.
The boom in cell phone popularity has led to various cell phone related offshoots such as cell phone etiquette, cell phones for children, cell phone accessories, and of course, cell phone competitive plans. The ease and flexibility that a cell phone now provides is contributing to the slow but eventual downfall to land line services. In the United Kingdom, it has been reported that the number of working cell phones actually out number the latest census.
Cell phone technology has leapt forward and a tremendous growth has only led to more competition. It will be interesting to watch the cell phone industry continuously make improvements and create developments that will lead to more user friendly cell phone features.

'My battery keeps getting low when I need it...'
'But I recharged it just this morning...'
'What's the heck's wrong with this battery...?'
'It's just a year old... How can it fail?'
These are common complaints, and the reason, we often conclude, is that it's the manufacturer's fault.
Fact is, cell phone technology has grown rapidly over the past 4-5 years, but battery technology just hasn't kept pace. Cell phones use lithium-ion batteries with a normal lifespan of 2-3 years. They are efficient power sources and often last a couple days when fully charged.
Even if we go back to as recent as 2003, it wasn't uncommon to find cell phones that gave just 1 hr of talktime with a standby time of under 24 hrs. These days, despite all the processing power involved, we can expect the typical Nokia or Sony cell phone to last much longer than that -- Say 4-6 hrs of talktime and 2-3 days of standby time. But the reality is, we often get just 50-75% of that. There are reasons for it.
It's important to note that the talktime / standby figures given by advertisers and manufacturers are just 'official' figures under "ideal" test conditions -- which means, the phone is tested with just the bare minimum of applications running (usually just the operating system) at room temperature, and used for no more than talking and sending sms.
Under "normal" usage circumstances, however, we do a lot more than that. Here are 8 of the things that a cell phone tends to engage in on a real-world basis:
1. Bluetooth on most phones having it is almost always on.
2. We've got multiple applications running in the foreground and background - even those we're not using.
3. Emails are being sent and the Internet is being browsed.
4. The brightness of our phone screen is set to high by default.
5. We've got sounds and vibrating alerts on, instead of functional ringtones.
6. For travelers and business users on roaming, the phone is constantly locating a signal -- which eats into precious battery time like no one's business.
7. We tend to overcharge our battery by keeping it plugged in for over 24 hrs, or the opposite -- completely discharge the battery before recharging it again.
8. Lastly (and more commonly), our phone is continually exposed to heat, cold, dust, rain, oil fumes, shocks and vibrations, including accidental drops on a hard floor.
The first 6 consume power while the last 2 can irreversibly damage the cell phone.
Power running low is one of the biggest complaints of cell phone users. And with new phones supporting features like wi-fi, webcam and gps - almost like a mini-computer - the strain on the battery is as enormous as that on the processor and memory.
The overall performance of our cell phone depends heavily on how efficiently the battery is used in day-to-day scenarios. By cutting down on just a couple of the points above, the battery will last longer -- not just between charges but also over its overall lifespan.

Putting together a cell phone fundraiser for your group is quick and easy. Here are some tips on how to start your program and most importantly, how to collect large amounts of cell phones.
Cell Phone Recycling First, when doing a phone fund raiser you need to know that some used cell phones are worth a lot more than others. Obviously, the newest models with all the bells and whistles are going to be worth the most.
Second, some older mobile phones have little value because they are obsolete, not in good condition, the batteries won't hold a charge, or won't turn on at all. So, an important point is that you need a company to work with that will at least pay something for every phone, not just the good ones.
Third, you don't want to spend your own money shipping in the cell phones that you are recycling, so you need a company that provides prepaid boxes. It works best if you can get boxes that are pre-addressed and have your group's ID number right on the shipping label. It works even better if you can use the shipping boxes as collection boxes, so all you have to do is tape them up and ship in your next batch of recycled cell phones.
Getting Cell Phone Donations When doing a cell phone fund raiser, getting lots of cellphone donations is critical to your success. So, how do you do that?
First, you have to get the word out to lots of people because most people don't get a new phone but every two years or so. You want to have their attention before the old one gets thrown away. And believe it or not, Americans throw away vast numbers of phones each year, roughly 20 million of them in 2006 alone.
Second, you want to make it easy for people to donate their old phones, so you have to have plenty of collection points. And the best collection points are where people get their new cell phones!
Third, you have to let people know that your cell phone fundraiser is for a good cause. Place large signs on your collection boxes that ask for their help and explain what the funds raised will be used for.
Example: 'Please donate used cell phones here because every dollar raised helps the local Food Bank.'
People are always more inclined to help when they know what the cause is and you make it easy for them to contribute. Keep it simple but be specific.
Cell Phone Fundraiser Summary The key to success is getting a large number of phones donated. Get permission to place your collection boxes at stores from the manager. In many cases, there are competing cellular service providers located in the same shopping center, so try to get a recycling box in place at each one of them.
Look for suppliers that provide prepaid shipping boxes and pay for every phone collected. Don't worry so much about who pays the most for high-end phones because the majority of phones donated will be older models.

Cell phones have in recent history become as much of us as our car or our wallets and purses. Have you ever left your cell phone at home and for the whole day felt almost empty, like something was missing? Not only that but how helpless did you feel not being able to contact the people you needed to talk too?
The Modern Cell Phone
Do you remember a time when the only functions a cell phone had was to either tell the time or make a phone call? Today the modern cell phone is made up of several different functions that could rival most computers 5 years back.
When digital cameras first came out with 2.1 mega pixels we were amazed at how easy it was to take 'high-quality' photos. Now every cell phone today comes with a digital camera of this same quality. Not only that, but video cameras have also become the norm in any newly released cell phone.
Now you don't have to carry around a camera with you. Taking a photo is as easy as pulling your phone out of your pocket and pushing a button. Not only that but most phones today allow access of memory cards, allowing you to store up to 2 gigabytes of storage. That's enough to take 1000 high quality digital photos!
A Musical Cell Phone
Portable music players have become big business recently, especially with Apple's creation, the iPod. This market has since then moved into the cell phone industry where if a phone doesn't come with a new cool way of playing music, no one is going to buy it!
Apple have recently released it's version, the iPhone which is set to become one of the most popular phones ever to be released onto the market. This phone doesn't look like it was designed to be a phone at all with it's sleek exterior, it mimics the iPod making it a very popular choice for young people.
Yes the capabilities of storing, playing and even downloading music is a must in the cell phone industry if a company wishes to make any sales.
What's Next?
It's hard to imagine that in just the short amount of time cell phones have been on the planet, they have come so far. What will they have in store for us in another 10 years? Will there even be the need for a cell phone? Perhaps all we'll need is a chip inserted in our head that will allow us to make calls and listen to music just by using 'mind power'!
Seems a little crazy doesn't it? Buy why not? Who's to say what the modern cell phone is going to be like in another 10, 20 or 50 years time. Whatever we're in store for, I'm certain there's going to be a lot of fun involved in using one!

As cell phones continue to shrink and their functions expand, they become increasingly inaccessible for millions of those with even a mild decline in vision, motor skills, or hearing. In addition, the associated cell phone plans are so complex that anyone who would benefit from having a cell phone for limited use, such as family communication and emergency use only, are deterred from making a commitment to such services. Obviously, there are a significant number of older individuals who fall into this category of people; those who could live more independently or more safely with such services but are limited by the complexity of the devices and the plans. The need to offer cell phones and cell phone plans better suited to those older individuals who encounter difficulty with the average device is slowly being recognized, giving options and hope to such users and those who may care for them. A year or two ago GreatCall introduced the Jitterbug, a cell phone designed with the needs of many older individuals in mind. The Jitterbug posseses larger buttons, big fonts on a more visible screen, good volume, and simplified, easy to understand functions. The phone is designed for the purpose of sending and receiving voice calls and messages minus many of the functions that complicate other cell phones and are generally not desired by many older users. Jitterbug phones even come complete with 24 hour operator assistance as needed to place calls or add individuals to a users personalized phone list. In addition, the Jitterbug offers cell phones plans that are affordable as well as comprehensible. There are a handful of plans to choose from but all offer calling that costs the same whenever and where ever a user calls and eliminate roaming, long distance, and time of day restrictions. None of the plans require a long term contract or termination fees and start as low as $10/per month. The Jitterbug however, has perhaps made another significant contribution to the evolution of cell phones and cell phone plans. It would appear that other manufacturers have taken notice and are awakening to the needs of this segment of the population, and the needs of all of those who would prefer more simplicity. Verizon recently rolled out the "Wireless Coupe" a cell phone targeted toward the older population. Certainly, this phone is a step forward although perhaps a bit more complex than the Jitterbug. With large buttons and big screen font, some "in case of emergency" buttons for single button dialing, and a discounted rate plan for those who use less talk time and have a fixed income it certainly is a step in the right direction. The cost of the phone is a mere $19.99 but requires a 2 year contract. Verizon's America's Choice 65 Plus cell phone plans are a compliment to their "Wireless Coupe". The two options include a single line plan which provides 200 anytime minutes and 500 night and weekend minutes for $29.99 and a two line plan with 450 anytime minutes and 100 night and weekend minutes for $59.99. Clearly, these plans are a bit more complex than the Jitterbug plans but should still be attractive to anyone who is seeking an option that is more appropriate and accessible for people needing basic calling functions only. Further evidence of the growing awareness of the need for simplicity and affordability is a cell phone plan AT&T announced a short time ago. AT&T's Senior Nation 200 Plan provides users with 200 anytime minutes, 500 Nights & Weekend minutes, and unlimited in network mobile-to-mobile calling all for $29.99/month. Although these recent entrants may not offer perfect solutions, they are certainly an indication that calls for more basic cell phones and cell phone plans are not falling on deaf ears. With more players recognizing the need to market to this segment of the population, consumers are bound to benefit as competition begins to heat up. Readers are encourage to learn more information about cell phone plans and cell phones by browsing the information available at homemedias.info, the author's online communications and home electronics store.
