Sprint has fired back at T-Mobile with its own smartphone buyback program, claiming that "it will meet or beat all competitors' pricing to ensure the best trade-in values." That includes instant store credit and up to $300 towards a new phone purchase or account credit.

In their press release, Sprint seems to go after T-Mobile specifically, stating:

Sprint also allows customers to trade-in up to three phones per line at any time and five in a calendar year. T-Mobile, on the other hand, only allows one phone trade-in per line and only allows customers to trade-in their phone when purchasing a new device. Sprint customers can take advantage of the trade-in credit at any time – whether they are buying a new phone, looking to purchase new accessories or want to use their trade-in credit towards their bill.
