TMobile please, Automatic cellular network selection is destroying your reputation. (Dropped service and swirched wifi preffered.)
Team T-Mobile, You need to pay attention to this thread. I think maybe AT&T is messing around with your customers. It may be unintentional, I don't know. When I'm driving, I switch to the AT&T ne...

Thank you so much for the reply. I used to be an AT&T customer and this is on a major Interstate area with good coverage for both AT&T and T-Mobile. Additionally, this is an issue with Android auto carrier select and or another correctable issue. If I hard code my network to T-Mobile my coverage is nearly 100% along the entire route with only two 5-15 second drops.
If I leave my network automatic, I get pulled to AT&T even in areas with good T-Mobile 5G coverage. Either the algorithm is broken or something else is going on.
This issue is combine with the issue that my Prefer Wifi for Cellular continually switches back to Cellular Preferred. A well documented bug and discussed on other threads for over a year. If I hard code my network to T-Mobile and deal with the constant annoying pop up messages about lost carrier, even though I'm on wifi. This bug stops happening, my Wifi calling stays on Wifi preferred.
This leads me to suggest either Samsung/Google Android have a major bug in their automatic cellular network selections/data roaming module or AT&T is messing with T-Mobile customers when they roam to their network, both in terms of data availability and changing the Wifi preferred setting.
Bottom line: T-Mobile needs to push hardcore on all companies involved to isolate the issue because it affects their customers service significantly and they haven't even acknowledged the issue as far as I can tell. Only reason I'm still with them is that, I still owe on these very expensive miniature hand held computers.
