Hi there
I apologize for any inconvenience caused by the need to reregister your myAT&T account, and for the lack of compatibility for your preferred internet browser. We aim to provide effortless service with our myAT&T site and this doesn’t line up with our goals. I can certainly look into any compatibility issues with our registration page and versions of other browsers. Thank you for bringing this to our attention.
Thanks,
Charise
