Hi
I’d be happy to help with your planned device switch for your GoPhone line! We can absolutely do this for you and it’s really simple! If you already have the tablet you wish to use on the line, you can drop by any AT&T store with the device to provision it on your line and provide the correct SIM card for the tablet. Or you can also reach our GoPhone Support department at 800-901-9878 for assistance!
To schedule an appointment at one of our retail stores, please click here. (https://www.att.com/maps/store-locator.html)
Thanks!
