T-Mobile (NYSE:TMUS) launched a buy-one, get-one-free promotion for the Samsung Galaxy S7 and S7 Edge, matching a deal AT&T (NYSE:T) launched just yesterday for the new, high-end handset.

Samsung Galaxy S7

Starting tomorrow, T-Mobile users who buy a Galaxy S7 online and add a line of service will receive the full retail price of the second phone of lesser or equal value in the form of a prepaid debit card via an online rebate. Families buying two new Galaxy phones can receive two more free.



The deal can be combined with T-Mobile's offer of a free Gear VR headset, a six-game bundle and a year's access to Netflix. Customers who switch from other carriers are also eligible to receive as much as $650 per line to cover the cost of moving to T-Mobile.

AT&T's Galaxy promotion can also be combined with the operator's offer of as much as $650 in credits per line to users who switch and buy a new smartphone on its Next plan. AT&T's new buy-one, get-one offer is available to both new and existing customers, although the second phone must be a new line of service, and -- like with T-Mobile's promotion -- both phones must be activated on qualified plans.

T-Mobile sells the 32 GB Galaxy S7 for $670 and the S7 Edge for $780, while AT&T is offering $695 as a rebate to users who buy either new Samsung device. Unlike T-Mobile's promotion, though, AT&T customers will receive their credits over 30 monthly bills that will kick in after three bill cycles or fewer.

T-Mobile John Legere took to Twitter to note the difference between the two promotions. "And unlike a certain carrier," he tweeted, "@TMobile we'll reimburse you on the second S7 edge, and not with a monthly bill credit! #ComeOnATT"
