T-Mobile today announced it was boosting the amount of data its “unlimited data” customers can use before they are subject to speed throttling from 32GB to 50GB, effective Sept. 20, 2017.

“Meanwhile, Verizon and AT&T sit at a meager 22GB, meaning Un-carrier customers can use more than 2x the data before prioritization kicks in,” wrote Neville Ray, T-Mobile’s chief technology officer. “Now, 50GB of data usage means a T-Mobile customer is basically the top 1% of data users, and to put it in context, you could stream a full two hours of Netflix every single day – that’s 30 SD movies – and never even reach that point! You’d still have roughly 8GB to go.”

Like other wireless companies, “unlimited data” does not actually mean “unlimited.” Providers allot a certain allowance of truly unlimited data which, once exceeded, subjects the customer to speed-reducing “throttles” until the next bill cycle begins. T-Mobile claims it only throttles customers when a customer exceeds their “prioritization” allowance — 50GB as of tomorrow — and the cell tower they are using is currently experiencing congestion.

“When T-Mobile customers who use the most data hit these prioritization points during the month, they get in line behind other customers who have used less data and may experience reduced speeds,” Ray wrote. “But this impacts them only very rarely, like when there is a big line, and it resets every month. If you have a lot of congestion in your network (I’m looking at you, Verizon & AT&T), these lines can be long and deprioritized customers can be waiting a long time.”

No wireless company will provide data on which cell towers are likely to experience the most congestion, how many customers are speed throttled, or what speeds customers will get for how long before the throttle usually drops. But it is definitely harder to hit 50GB than 22 or 32GB, which means fewer customers are likely to find their wireless data connections throttled.

There has been no response yet from T-Mobile’s competitors — AT&T, Sprint, and Verizon.
