T-Mobile changes its trade-in dealsAccording to The Mobile Report, it obtained some leaked documents which suggest changes are coming to T-Mobile trade-in promos. In the past, T-Mobile only accepted trade-ins for damaged devices from the low-end “free” 5G phone range. This means that the device you’re trying to trade in cannot be a super old device. Finally catching upWe’re not sure why it took T-Mobile this long, but its competitors like AT&T and Verizon have long accepted broken devices for trade-ins. For example, AT&T requires that a trade-in device’s inherent value be of a certain minimum.
