T-Mobile details iPhone 18 Pro trade-in credits over 36 months

T-Mobile announced iPhone 18 Pro launch offers on September 10. Its highest advertised credit was up to $1,200 toward an iPhone 18 Pro model for customers on Experience Beyond 2.0, Experience Beyond or Go5G Next who traded an eligible device in any condition or switched a line. The release listed lower credit ceilings of $930, $730 and $300 for other plans. It said the credits would be delivered through up to 36 monthly bill credits, with taxes due.

For a US buyer considering a refurbished or open-box iPhone instead, the headline number is only one part of the cost. The relevant plan, eligible trade-in device and length of bill credits all affect the comparison. A separate upfront purchase of a refurbished phone can be assessed against a different monthly service plan. That is a buyer-side comparison, not a claim that one route is cheaper. The announcement also described EIP Flex 36 financing for well-qualified customers, with $0 due at checkout under its stated conditions.

The newsroom post does not provide a full per-device trade-in table or a firm end date for the iPhone credit offers. It also leaves eligibility and plan terms to the offer details. Confirm today’s plan cost, exact device quote, taxes and credit schedule before relying on the advertised maximum.
