AT&T Wireless' customer service is hopelessly fragmented, with a terrible IVR interface and CS agents without the tools to help outside a very narrow range. My elderly parent has had an "AT&T Mobility" account for years, consisting of a wireless (3G cellular-based) home phone base station into which she plugs her old-fashioned wireless phone system. Recently AT&T required her to upgrade to a 5G device. Same idea of a little base unit (model IFWA-40) which connects to the cell unit for VOICE ONLY and into which her normal Panasonic wireless phone plugs. Setting that thing up has been a nightmare because the IVR system consistently sent me to the wrong department. "Wireless phone" nope. "Home phone" nope. "AT&T Mobility" - YES! Except if you mention the phrase "home phone" at all - even though you specifically also said "wireless" and "5g" - the CS rep will say "wrong department" and send you back into on-hold hell.
Even when you finally get to the right department (it's the "wireless internet" department, EVEN THOUGH THIS DEVICE DOES NOT PROVIDE INTERNET), they do not have the skills or tools to troubleshoot issues. About 75% of the time I was transferred to "advanced support" which, as of this writing, has attempted and failed 3 times to successfully disable call-waiting and enable voicemail.
It is not a mistake that AT&T is consistently among the very worst-ranked companies.
