AT&T has introduced an aggressive offer, which is basically against T-mobile, and gives users up to $450 per line if they switch from T-Mobile to AT&T and trade in an eligible device.
Obviously getting the complete $450 may not be easy as there are some conditions. T-Mobile customers who will switch to AT&T will receive $200 credit per line when they transfer their line to AT&T and choose a AT&T Next plan, activate a device they currently own or buy a device at its full retail price.
Customers will receive up to $250 when they trade-in their old device. Although they didn’t specify the devices which are currently eligible for the promotion, but it simply mentioned, “many of the latest and most popular smartphones will qualify for a value of $250.” The amount you receive will depend on the condition of the handset you’re trading.
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 NextSM plan, buy a device at full retail price or activate a device they currently own.
Lastly, the value will be in the form of promotion cards, which can be used to buy AT&T products and services, including the phones. The offer is available for a limited time so you need to act fast.
