Red Pocket has all networks. GSMA is AT&T, GSMT is T-mobile. So different network.

Strange that you had success with Wi-Fi on. Most were succeeding with it off. But gives us something to explore further.

I have success! MMS, group text, works. I want to provide a bit of the detail for me.

I'm in the Boulder, CO, USA area.

Red Pocket gives APN information on their website:
https://help.redpocket.com/hc/en-us/articles/360042491332

The APN name is different there compared to the Bounty thread (which gives PRODATA). That doesn't seem to matter.

The MMS Proxy entry does matter. I found that the hostname didn't work, but the IP address did.

There was a suggestion around here that this might work better with WiFi OFF. I found that REPLIES from other phones to my group text (MMS) initiated from my P3a FAILED with WiFi OFF. When I turn WiFi ON, then group text replies SUCCEED. Odd that MMS would fail to be processed correctly on the P3a when WiFi is off.

I can't get my Google Fi SIM to work. It's got to be something about the APN settings. I think it's on the same network, but maybe GSMA with Google Fi might be on a network that doesn't work in my location? Maybe it's using T-Mobile and Red Pocket is using ATT? I don't know.

It configures itself as T-Mobile. I reboot with wifi off. I can MMS photos fine, but when they are sent to me, from the same number I send to, it comes in to x-ofono-unknown, in other words, an unknown number. I was messing with this mostly in the development channel, and I when I received MMS I just got a delivery failure with the block of characters, but when I switched to the RC channel, I can receive to unknown number.

VoLTE is not already working on any phone or carrier.
On day it will.

So from the screenshot where you see "Canaux - Stable" click there to choose RC (recommended). After that, go "back" and it should prompt you to "Download and Install" (will then reboot and install RC).

You can see it in settings for updates, and even more precisely in about settings :

Have checked MMS and AT&T internet (and unchecked latter, also), stopped wifi, set to 3G and slower, all to no avail. Do I need to change APN settings or what else could I try?

You can keep cellular data at 4G mode and send / receive SMS and MMS reliably, and of course calls are working fine. What doesn't work is MMS when on wifi, this is a separate bug broader than just Pixel 3a phones.

But, we're very close to fixing the problem with all GSM carriers.

For AT&T - Red Pocket, H2O, Straighttalk. Some have had success with Cricket.

For T-mobile - anything is good. Mint is cheap, US Mobile, walmart family mobile, just about any will do.
