Consistent with their goal of making things easier for customers, T-Mobile has developed an app that users can run to unlock their devices when their contract is up or to temporarily unlock the device when traveling abroad. The biggest downside at present is that only a few customers can actually use the Device Unlock app – those who have a Samsung Galaxy Avant. Still, it is good to see T-Mobile making this move.
As customers look at T-Mobile to figure out who may eventually benefit from this app, there is more good news. T-Mobile is making it available through Google Play. Presumably, this means current owners of T-Mobile devices may be able to unlock their devices as support is added to the app.
You can check out the Play Store entry for the Device Unlock app using the links below even if you do not have a Galaxy Avant from T-Mobile.
