How do I unlock my mobile device from a US carrier?

In order to use GigSky’s service, your device must be unlocked. This article explains how you can go about unlocking your device from a US carrier. If you didn’t get your device from one of the US carriers, please contact your home carrier about unlocking your device.


Unlocking happens automatically as long as you do the following:

  • Purchase and activate your device on Verizon

  • Keep your account current by making your payments on time

  • 60 days after purchase, your phone will be unlocked automatically

This applies whether you paid for your device in full or if you’re on a payment plan.

From 2016, most of UScellular’s phones have been sold as unlocked. You can find a list of the phones that are sold as locked on the UScellular website. These phones are locked for 120 days by default, but there are ways to unlock them sooner if you’re a postpaid plan user:

  • Pay for your device in full and have an account in good standing

  • Be a former customer who has completed all financial obligations to UScellular

Prepaid plan customers have to wait the full 120 days, after which the phone will be unlocked automatically.
