No incoming SMS/MMS
Just got my Red Pocket SIM (AT&T Network) and was running my initial tests on my Pixel 3a.
Sending and receiving calls works flawlessly! as well as the Cellular data. Issue seems to be receiving SMS/MMS messages. In my testing I attempted to send an MMS message and received an error about improper APN settings preventing the receive. I reset my APN settings per Red Pocket's provided settings for the AT&T network. I can now send SMS messages (sent many of them), and MMS as well, but receive nothing. Any suggestions as to troubleshooting steps I may be able to try? I am a long term Linux user so any command line debugging steps would be welcome.
--Update 54 minutes later one of my SMS test messages came through

@CJLes72 GOOD news! Incoming SMS is now reliable on the P3a in the US / Canada (due to disabling "IMS" on the phone so the carriers don't convert sending SMS over IMS and keep sending it the "old school way" which works). This is quite reliable now.
Also, MMS photos in and out work reliably with wifi turned OFF: with wifi ON they do not work right, but it is broader than the P3a.
Here is the link to the post where @fredldotme references these fixes: https://forums.ubports.com/topic/6039/bounty-for-pixel-3a-halium-9-stability/18?_=1630188659271
