T-Mobile USA rolled out its Data Stash data rollover feature to Simple Choice Prepaid $60 and $70 plan customers. Data Stash lets you roll over your unused high speed data each month.
While there's no limit to the amount of data you can roll over, unused rollover data expires after 12 months. That effectively limits the amount of data you can rollover to 36 GB on the $60 plan which comes 3 GB of high speed data per month or 60 GB on the $70, 5 GB plan.
Then last month, T-Mobile added Binge On unlimited video streaming to Simple Choice Prepaid plans that include 3GB or more high speed data per month. With Bing On, data used while streaming video from 24 services including Netflix, Hulu ESPN, doesn't count against your high speed data usage bucket. A downside of Binge On is that when it's enabled video streams are are compressed and downscaled to 480p quality which T-Mobile says uses only a third as much data as unoptimized video.
Unlimited Data Stash and Binge On are both great features but there is a catch. When T-Mobile launched Binge On they capped Data Stash at 20 GB. If Binge On is enabled, which it is by default, you can only have a maximum of 20 GB in your Data Stash instead of 36 or 60 GB.
All on T-Mobile's current plans have a 20 GB Data Stash cap. But T-Mobile is letting users on grandfathered plans with unlimited Data Stash, including the $60 or $70 Simple Choice Prepaid plans and their postpaid equivalents, keep it, but only until Dec 15, 2015. T-Mobile is essentially giving grandfathered customers a free trial of Bing On so they can see if they like it enough to give up unlimited Data Stash.
To opt out of Binge On, text DATAROLL to 6255. Warning, you only want to do this if you are on the grandfathered $60 or $70 Simple Choice Prepaid and you are willing to give up unlimited video streaming in order to keep "unlimited" data rollover.
Unless you rarely stream video from the services that are unlimited under Binge On, I don't think it makes a lot of sense to opt out, especially for $60 plan users. 20 GB is still a lot of roll over data. Even if you opt out the fact that roll over data expires after 12 months makes it hard to accumulate much more than 20 GB unless you hardly use any data most months.
