Welcome to the new AT&T Community
We've got a fresh look! Take the tour to see what's new.
My theory on why AT&T Addressbook is not working for many customers is the IMEI Numbers in the AT&T Database.
The reason for my theory is that all of my IMEI Numbers are screwed in my account.
When I login, all my devices are showing incorrect devices.
When I change them to the correct device, it says that it saves, but a screen refresh caused the devices to default back to some random device.
I think the IMEI Numbers are all messed up, and this is causing registrations to fail.
If I cannect on Device with IMEI # '1212121212' and try to register the AT&T Address Book, and it sees that IMEI Number is not on my account, wouldn't that cause the failure?
I'm just thinking logically here... :-?
even I am experiencing the same problem. It says unable to register. If there is anyone who can help me, that would be great
It might be a good idea to contact customer care for help, they can verify that your account and equipment are set-up correctly, I would start there. You can call us @ 1-800-331-0500 or send a private message by clicking here.
