- – 1: First, be sure you have the Official T-Mobile Device Unlock App installed. If you don’t have it, you can download it from Google Play. Be sure that it is by T-Mobile USA.
- – 2: Connect to Wi-Fi.
- – 3: Open the App
- – 4: Continue, and Click Permanent Unlock.
NOTE: If you successfully connect and it still shows an Ineligible, then wait a couple of hours and try again. Sometimes the servers take a while to update.
- – Continue, and the T-Mobile Device Unlock App will finish the process within a few moments.
- – Congratulations! Your phone is unlocked and for use with any GSM compatible phone service carrier!
Remember, for Internet Data and Multimedia SMS Text Messages, you will want to change those settings based on APN/MMS settings provided by your new carrier. This is not related to the unlock, but we get asked all the time.
Please note that the Wi-Fi Calling found on some T-Mobile phones is exclusive to T-Mobile, and will need to be disabled, as the Wi-Fi calling is not compatible with any other carrier and is completely unrelated to the SIM Network Unlock.
