When will AT&T Support Advanced Messages on more Unlocked Phones?
I found this Service capabilities for your unlocked device PDF that was Last updated: February 27, 2020. I have an unlocked LQ G8 ThinQ and the phone clearly supports Advanced Messaging since there's an option for me to turn it on in the stock Google Messaging app. However, this capability hasn't worked ever since I put the phone on the AT&T network and now I understand why after finding this PDF.
AT&T: Why do you support Advanced Messaging on so few unlocked phones? Is there a plan to add support to more unlocked phones? If so, when? The AT&T branded LQ G8 ThinQ supports it so I don't understand why the manufacturer unlocked version doesn't.
General rant and complaint: Why isn't AT&T customer service aware of things like this PDF? I called multiple times and spoke with clueless people who wasted my time. I've seen so many posts on this forum with other customer complaints similar to other experiences of mine, e.g. slow text messages, dropped text messages, issues with AT&T not recognizing IMEI numbers, etc. Overall, I can make phone calls, Internet works ok, etc. but jeez, get your act together when it comes to customer service. It's just terrible.
