T-Mobile’s Keep & Switch promotion has an upgrade for a limited time.
The promotion gives a rebate card to switchers that pay off their device with their old carrier. The customer can then bring that device to T-Mobile, submit a bill, and get the rebate. Typically the maximum rebate amount is $650, but recently it’s been increased to $800.
Customers can switch from any eligible carrier, which are Verizon, AT&T, Spectrum, Xfinity, US Cellular, Claro, and Boost.
