In August 2014, after the US government approved cell phone unlocking as legal, T-Mobile and Metro PCS did their part by allowing some of the models they sold to be released using an app officially sponsored by them. It was called the ‘Device Unlock App,’ like unlock Cricket which allowed users to unlock their phone temporarily or permanently, as long as the phone was not reported for theft or non-payment.
Initially, the only phone that could be unlocked in this way was the Samsung Galaxy Avant, considered medium or low range. However, new and more models have recently been enabled for unlocking through this app. This is the reason why we are going to talk about the Device Unlock App in this article.
Where Can it Work?
You may find this application pre-installed on your cell phone, especially if you bought it at T-Mobile or Metro PCS. You can also download it from the AppStore. Be careful, as the application does not work on any phone, although it can be downloaded on most. Here is a list of models that can use the application:
- Alcatel (One Touch Pop Astro, One Touch Evolve, OT-5024N, OT-5042T)
