SMS over WiFi issues continue
I’ve searched the vast similar issues reported here. My problem: SMS, MMS, and group texts frequently either, aren’t received ever, come in all at once in a dump and out of order, and when sending it’s either delayed significantly, or kicks back that the message was not sent and I have to attempt to resend it. This problem has occurred over the last 3 years using an iPhone SE 2016. I do not have this problem using iMessage.
I am currently using an iPhone 12 mini on iOS 14.4.2 and this problem still exists. This has me rule out the device. I have tried several suggested methods including, restarting the device, resetting network settings, resetting all settings, factory resets, WiFi calling toggles, airplane mode with cell data off and WiFi on. These all work for a very short term to reestablish whatever happens behind the scenes at ATT but the problem recurs shortly thereafter, even if the device shows ....ATT - WiFi, confirming its on and connected as it should be
More background: this happens particularly when I’m in buildings with horrible cell coverage, at home where there is almost no cell coverage, or any area with little coverage but has strong WiFi available. NOTE, the WiFi signal and throughput is strong. 300Mbps down 30Mpbs up so this tells me it’s not the network connection. Webpages and any other apps requiring data load and work beautifully. SMS over WiFi doesn’t. It might help to note that my number was originally a Verizon number ported over to Cingular early to mid 2000s. Other contacts are on different carriers and using a mix of iPhone and android devices.
But what I’ve stated above as attempts resolve this, leads me to believe it’s almost certainly some issue with, my line or ATTs network.
I’m posting here because maybe there is something that I haven’t tried. I’m loyal to the service I’ve had otherwise with ATT, but since this phone is bought outright, I’m not tied to a contract so if this doesn’t get fixed I’m most likely going to try another carrier hoping the problem disappears. And maybe if there’s a solution that works, it can help someone else having the same problem.
