After the restart, the Device Unlock app is gone from the MetroPCS folder.

If your unlock request failed, then there are 2 choices

1. Serve the Unlock Period to make your device eligible for free unlocking

To unlock your Aristo 3 / Aristo 3 Plus MetroPCS you must have your device active on MetroPCS network for at least 6 months. I’ve personally observed that if you purchase an activated LG Aristo 3 from eBay, then even without buying a monthly plan the device gets eligible for unlocking after 6 months period.

Once the 6 months period is over, you need to repeat the above procedure once again using the pre-installed device unlock app.

2. Buy the LG Aristo 3 App Unlock Service

If you cannot wait for 6 months and wish to unlock your phone right away, then you need to purchase the LG Aristo 3 app unlock service.

After paying for the service they make your device eligible for unlocking. You need to use the same procedure as explained before to unlock your phone using the device unlock app.


Please share your outcome. Which method worked for you?
