T-Mobile will be forcing customers on older smartphone plans to move to newer, more expensive plans, according to information that has been shared on Reddit. The migration will be automatic, but customers can contact support to ask to opt out of the migration.

Those who had the prior Magenta and One plans will be upgraded to Go5G, while those on the Magenta 55+ plan will be upgraded to Go5G+. Simple Choice and Select Choice users will be moved to Magenta or Essentials Select.

“We are not raising the price of any of our plans; we are moving you to a newer plan with more benefits at a different cost,” reports ArsTechnia as saying about T-Mobile’s move. “That’s the talking point customer service reps are supposed to use if a customer mentions that they saw commercials ‘about how T-Mobile won’t raise the price of my plan.'”

Adds Cnet: “There’s a window to opt out of the change. But if you don’t, expect to pay more for a new plan.”

With these migrations to new plans, customers will see price increases of $5 to $10 per line depending on current plan.
