Our phones work best on the Cricket network, but we'll provide the unlock code if you meet the following requirements:
The device you want to unlock has been active for at least six (6) months of paid service.*
The device you want to unlock is designed for use on and is currently locked to Cricket's network.
Your device hasn't been reported as lost or stolen.
Your device isn't associated with a fraudulent account.
*The 6 months paid service requirement does not apply to Cricket devices purchased by Unlimited Plan customers before January 4, 2018.
If you meet these requirements and would like to unlock your device, please call or chat with a Cricket Support Advocate or visit your local Cricket Store.
