T-Mobile has rebooted their Prepaid offerings to really put the pressure on other prepaid carriers like MetroPCS, Boost Mobile, and a slew of others. What makes T-Mobile offering different is that it runs on T-Mobile’s nationwide GSM network. This means that you can buy ANY GSM phone that is either for T-Mobile or that is unlocked, buy a T-Mobile pre-paid kit, stick the SIM card in the phone, and your in business. Now you can do unlimited calls and text messages from anywhere to anywhere in the United States for $50 bucks. If you donâ€™t really do a lot of talking but texting is big on your list, there is the $15 a month option that gives you unlimited text messaging and .10 a min per call that is deducted from the $15.00 a month charge. Thatâ€™s a pretty good deal. Â So if you are planning to upgrade your BlackBerry, you might consider recycling it by buying one of these prepaid plans, and letting your kids text to their hearts content.
