DALLAS — AT&T is now offering T-Mobile customers $450 per line when they switch to AT&T and trade in an eligible smartphone.

In addition to a larger and more reliable 4G LTE network, T-Mobile customers who switch to AT&T will benefit from a superior smartphone line-up and award-winning customer service.  With AT&T, customers can take advantage of AT&T’s new Mobile Share Value plans, which offer data and unlimited talk and text starting as low as $45 per month with no annual contract. AT&T Next  offers customers the chance to upgrade to a new smartphone every year for $0 down.

Beginning Jan. 3, under the limited-time offer, T-Mobile customers who switch to AT&T can trade-in their current smartphone for a promotion card of up to $250, which can be used toward AT&T products and services.  Trade-in values will vary based on make, model and age of the smartphone, but many of the latest and most popular smartphones will qualify for a value of $250.  T-Mobile customers can receive an additional $200 credit per line when they transfer their wireless service to AT&T and choose an AT&T Next plan, buy a device at full retail price or activate a device they currently own.
