TL;DR
  • T-Mobile T-Mix customers can change their subscription Picks during the final 10 days of each 90-day cycle.
  • Missing the window means existing subscription perks automatically carry over into the next cycle.
  • A $15 charge per eligible partner perk allows customers to release it early for a phone promotion, while T-Mobile’s own perks remain changeable anytime.

T-Mobile’s new T-Mix plans promise something wireless customers have wanted for years: more control over what they’re paying for. But that freedom comes with a few ground rules, including a limited window to change perks and a potential $15 charge if you need to switch early.

Unveiled last month, T-Mix lets customers choose benefits such as Netflix, Xbox Game Pass, and phone deals instead of getting the same set of extras as everyone else. These benefits are called Picks, and customers can change their selections every 90 days. However, that flexibility goes beyond what T-Mobile’s initial announcement explained.
