T-Mobile has unwrapped their third holiday promotion, and this one is aimed at AT&T’s faithful. “Un-Carrier Unwrapped” holiday promotion #3 offers AT&T customers a 128GB iPhone 6s  for $200 off, bringing the price of the top of the line 6s down to the same price as a 16GB base model.

Switch from AT&T to T-Mobile and They'll Give You a 128GB iPhone 6s for $200 Off

The offer is open for any AT&T, Go Phone, and Cricket postpaid and prepaid customers that switch their phone number to a Simple Choice postpaid plan between December 4 and December 13. AT&T customers can also combine the deal with T-Mobile’s Carrier Freedom promo, which give switchers up to $650 toward any balance they owe, or to pay off early termination fees when they trade in an eligible device.

And, the “gifts” just keep on a comin’, as T-Mobile will also knock up to half off its lineup of in-store financed accessories, such as UE Boom and JBL Bluetooth speakers, top-of-the-line headphones, Fitbit fitness trackers, Guitar Hero Live for iOS and more. That could add up to as much as a $125 off an accessory.

The offers are all part of T-Mobile’s “Un-carrier Unwrapped” holiday promotion. The magenta carrier earlier announced three months of free unlimited LTE data for all Simple Choice postpaid customers, and a $200 bill credit for Sprint customers who switch.

T-Mobile’s bombastic CEO, John Legere, recently tweeted that an “Un-carrier Unwrapped” gift for Verizon customers is on the way.
