"T-Mobile will never change the price you pay," the carrier told users in
2017.

Unfortunately, the promise wasn't as simple as T-Mobile claimed it to be in
that press release. T-Mobile also published an FAQ that answered the
question, "What happens if you do raise the price of my T-Mobile One
service?" It explained that the only guarantee is T-Mobile will pay your
final month's bill if the price goes up and you decide to cancel.
