Phone unlock code doesn't work

Hello @Nippa9,

Thank you for informing us.

We're sorry to hear that you're experiencing issues while trying to complete the unlock process.

Unfortunately, there is only one unlock code that matches up to each device so we don't have access to another unlock code for your cell phone.

We recommend that you contact the manufacturer of your device for further assistance.

Hope this helps!

Hey there @Nippa9 we'd be glad to help with your device unlock process as you may be subject to your last try.

Please provide us with the make and model of your device, so that we can confirm the most reliable device specific instructions for you. Also, we'll need to know if this device was operated on a postpaid or prepaid plan.

Next, let us know what error message you're receiving when attempting to unlock either online or physically using your device. Feel free to locate your device on our Unlock Code Instructions Manual  to better understand how to properly and successfully unlock your device.

Let us know how this information helps, and the needed details to assist you further.
