There are many loyal T-Mobile customers out there, just like there are many loyal customers at AT&T, Sprint and Verizon who have been there forever...or it seems like forever. Many of those that have been with T-Mobile for a few years are probably grandfathered into an old plan that no longer exists. T-Mobile has changed their plans quite often lately. The carrier is getting ready to get rid of all these legacy plans and move subscribers over to new ones.
Instead of them moving grandfathered customers to new plans without Unlimited data or having high prices, T-Mobile is actually giving them a special unadvertised rate plan. T-Mobile said that they would provide these customers with a "similar or better features at a comparable price." Basically, these customers will get to choose from a variety of plans that are not available to new customers. Som starting as much as $20 per month, the cheapest individual plan at T-Mobile right now is $50. So it seems like a good move to me.
Over on HowardForums, a user posted a letter reportedly from T-Mobile, that lends credence to the claim of the unadvertised plans. It would move the customer to a $45/month price tier that provides unlimited voice, text and 4G data. This transition is slated to begin in November, so you've got a few weeks. But if you don't like this plan (I don't think anyone would hate it, unless coverage is an issue, but then why were you with T-Mobile anyways?) T-Mobile is allowing you to jump ship with out any Early Termination Fees through February 21st, 2014. So if you were looking to jump over to AT&T, Sprint or Verizon, now is your chance to do it without any extra fees.
Here is T-Mobile's full statement:
Maintaining thousands of rate plans is the norm in the industry, but we think it creates unnecessary complexity. Simple is better, which is why we're reducing the number of older plans in our systems. We're giving customers on these plans the opportunity to choose a plan that best meets their needs. For the vast majority, their plan will provide similar or better features at a comparable price.
