This latest war between cell phone carriers began a few weeks ago when AT&T offered $350 to T-Mobile customers willing to switch to AT&T.
But that was nothing compared to this latest volley.
T-Mobile is fighting back by offering customers considering switching carrier seven more money.
The provider is also extending the offer to customers of Verizon and Sprint, as well as AT&T customers.
It will pay you as much as $650 make the jump to T-Mobile.
How it Works
If you agree to switch carriers....
-T-Mobile will pay your termination fee for every phone in your plan.
-T-Mobile will also give you up to $300 per phone trade-in, depending on which phone you currently have.
-The total you can receive is $650.
There is a catch: You will have to buy a new phone from T-Mobile.
You cannot keep your existing iPhone or Galaxy, though you will be able to transfer over your phone number.
What You Will Pay
That new phone you must buy from T-Mobile will be sold at full retail price, which means you can expect to pay between $200 and $600 for a new smartphone.
T-Mobile does not subsidize phones, so you cannot get a new iPhone for $199 as on other carriers.
But given what they are paying you to switch, the cost may be negligible.
In addition T-Mobile will not require you to sign a 2-year contract, and its monthly data and voice rates are lower than AT&T or Verizon.
So it may be a good deal, depending on what they offer for your old phone. That way you don't waste your money.
