T-Mobile Giving Away iPhone 7s in Exchange for Service

Customers who trade in a qualifying smartphone and sign up for a T-Mobile One service contract with their existing number can get an iPhone 7 free, or an iPhone 7 Plus for $100, in a promotion that runs through March 16, said the carrier Friday. The deal is available to new and existing customers. Customers will get instant credit for trade-ins, and after registering online, will get a prepaid MasterCard in the mail with a rebate that can be applied to their remaining equipment installment plan balance, T-Mobile said.
