T-Mobile currently offers the highest deprioritization threshold of the four major U.S. carriers, and soon the gap between it and its competition could grow larger.

T-Mobile will allegedly increase its “Fair Usage threshold” to 50GB on September 20th. That’s according to reports Android Central and TmoNews.

This deprioritiztion threshold is not expected to change every quarter and will no longer involve a specific percentage of data users on T-Mobile. The new limit is expected to work just like the current one, though, which means that T-Mobile customers that use more than 50GB of data in a single month may have their data speeds slowed at times when the network is congested for the remainder of that billing cycle.

T-Mobile’s deprioritization threshold is already well ahead of the other big U.S. carriers, with Sprint’s limit at 23GB and both AT&T and Verizon at 22GB. While some customers likely won’t be happy that a deprioritization threshold is still in place, it’s unlikely that we’ll see that limit completely disappear, at least not for some time. At least increases like this give customers more data to use before having their usage deprioritized.
