T-Mobile has reached out and said that any users who haven’t seen their new pricing changes reflected on their bills yet will do so very soon. There were no oversights or system errors, as I mistakenly thought, that sent out the same bills to these customers.
T-Mobile says that these users are on the legacy billing cycle and the bills that they’ve received in April are for March instead when the prices had not been increased. This means that these T-Mobile users will likely see increased bills next month in May when their bills will reflect the service that they received throughout April.
While this is a huge bummer for anyone who thought that they’d been spared the price hikes it is also somewhat reassuring to know that everyone is on the same page with T-Mobile. This not being due to system errors is also good news as the last thing anyone wants right now is their telecom company to have compromised servers. There’s no telling when hackers like the group Salt Typhoon may try to infiltrate U.S. systems again.

If you are a T-Mobile customer who received an unchanged bill then you’re likely on the legacy billing cycle and will get the updated bill next month.
