T-Mobile imposes data cap of 1.2TB/mo.

T-Mobile’s 5G home internet power users may have noticed their speed getting slower by the end of their billing cycles.

That’s because as of Jan. 18, 2024, T-Mobile instituted a data cap of 1.2TB/mo. for new 5G Home Internet customers. Considering U.S. internet users consume just over a half terabyte a month, a terabyte data cap could affect more people in the future. For now, though, T-Mobile says they expect only a handful of high-data users to be affected. 

ZDNET reported that a T-Mobile memo said, “Making sure all customers get a great network experience today and in the future is our top priority, so when a customer uses more than 1.2TB within a billing cycle, they may encounter reduced speeds during periods of network congestion. Their data and prioritization will be reset with their next billing cycle.”

Data caps exist for all types of internet connections, but particularly for satellite users. Often going over your provider’s cap can result in speed throttling for the rest of your billing cycle, but some providers tack on extra charges as well.
