IMEI not found

Device has been used with different att sim card.

I got a new sim and when I try to activate I get "GA207 : We don't recognize that 15-digit IMEI number."

I checked IMEI on device and it is typed correctly on submittal form.

What is needed done to rectify this.

We'll be happy to look into what's going on with your IMEI @Chadison.


Is this a device you're currently using or have you purchased another device? If so, is this a brand-new device or a refurbished device?


We look forward to your response. With more details, we'll have a better idea of how to proceed.
