T-Mobile’s forced migration is wiping out free lines and jacking up bills (Update: restored)

Credit: Joe Maring / Android Authority TL;DR T-Mobile’s forced migration to Experience plans is causing some customers to lose long-standing free line promotions and pick up unexpected charges. One customer says promotional credits that were supposed to carry over have disappeared, turning some monthly bills from around $50 to more than $300. Some users also report free lines being deemed “ineligible” after the switch.

Update: July 16, 2026 (7:03 PM ET): T-Mobile has reached out to Android Authority with this statement: “Our priority is to ensure customers keep the promotions, credits and benefits of their current plan. We’ve identified technical issues affecting a very small number of customers and are working quickly to correct them. For some of those customers, free line promotions were not reflected correctly following migration due to a delay in applying promotional discounts.

Those free lines remain free, and we’re restoring the discounts, backdating them where needed, and reprocessing accounts to ensure customers receive the benefits they were promised. We’re also investigating reports that some people were incorrectly billed for Hulu following migration and are actively working to identify the cause.
