T-Mobile’s forced migration is wiping out free lines and jacking up bills

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.
