Back in March, T-Mobile updated their deprioritization limit from 28GB to 30GB. Now, only a couple months later, T-Mobile is making another adjustment to the limit by raising it to 32GB. If you are not familiar with deprioritization, this means T-Mobile may throttle your connection speeds if you have used over 32GB of data in a month and you happen to be connected to a congested tower. Once a tower is no longer congested or you move and connect to a different tower, speeds will return to normal 4G LTE speeds.
In case you are wondering how T-Mobile is arriving at these limits, it is based on their top users. T-Mobile's policy is to trigger deprioritization for the top 3% of customers using data. According to their updated terms, T-Mobile analyzes this on a quarterly basis. Thus, for the first quarter of 2017, customers using 32GB or more of data in a month constitute T-Mobile's top 3% of users in terms of data consumed.
For comparison, AT&T and Verizon both set their deprioritization limit at 22GB per month and Sprint has theirs set at 23GB. Unless the other carriers make similar adjustments, T-Mobile will be offering a generous allotment of data before deprioritization kicks in which might be a factor for some users looking to squeeze the most performance out of their carrier, especially if they live somewhere prone to network congestion.
