If your device is unlocked and meets our compatibility requirements (contains proper frequencies), all you need to do is pop your activated US Mobile SIM Card into your phone. (For full functionality, don’t forget to add APN settings!)
If your device is locked (contains software restrictions preventing use with other carriers), you will need to contact the carrier your purchased your handset from in order to have it unlocked for use with your US Mobile SIM Card. Check out this blog post for the 411 about locked phones.
We’re more than happy to walk you through the process. Our 24/7 Customer Service is here for you!
