T-Mobile automatically migrates legacy plans to modern tiers, potentially raising bills
Thousands of longtime T-Mobile customers on old plans will be automatically moved to the current plan lineup within weeks, with notifications via text or the T-Life app; some may see about a $4 per-line price increase, though the new plans offer features like international roaming and faster 5G. The change is part of a broader effort to simplify internal systems by retiring over 1,100 legacy billing codes; customers unhappy with the auto-upgrade can only switch to another T-Mobile plan or provider.
