Question S23 Ultra - Google messages Dual Sim does not work

[AA37Q]

I recently upgraded to a unlocked s23 ultra from a T-Mobile s20+ and immediately I started having issues with google messages. I had google messages installed on my s20+ with no problems switching between sim cards during a conversation. On my S23U, the app forces sim 1 to be default and when I attempt to use sim 2 it automatically defaults back to sim 1. Its so frustrating because it worked perfectly fine on my old phone and now it just wont.

Google says its a Samsung problem, Samsung says its a google problem. Both are pointing fingers at each other. Using Samsung's default app works fine and even using TEXTRA works fine as well. I hate the fact I cant use RCS anymore (unlocked phone) and can't use my computer at work to reply to texts.

I have uninstalled the app, cleared the cache, clear the data, even installed the APK from a 3rd party to see if it was a Samsung skin issue, rebooted the phone, even did a factory reset. Nothing worked.

Slot 1 is physical T-Mobile, Slot 2 is mint mobile esim. Same configuration on my old S20+
Please, can anyone help?

After some brainstorming, while I can't say thus 100% the issue but it may be the February update that may have caused this problem. The dual sim function worked fine for the 1st 2 days I had the phone but then when it was updated no it wont work. Anyone else having this issue?

Unfortunately I have not found a solution. Everytime an update gets released I hope it gets fixed but nothing so far. I've reverted to using samsung messages for now.

I do want to do a factory reset without using smart switch and see if it works but I haven't had much free time recently

Odd thing, i wanted to test google messages pairing and Dual sim works fine on PC when selecting a sim but the native android app doesn't work for me. It always defaults to Sim 1 when i try to select a sim 2.

How can I submit this issue to google directly besides using the feedback option in the app. I see there's a website for official google bug tracking but don't know how to report it

Weird. Mine works just fine. I have physical Sim 1 as Tmobile and Esim as ATT

I'd like to pick your brain. Do you have a factory unlocked U1 S23U? Do you have google's carrier services installed?
What app version of google messages are you running? Are you running the March 2023 software versions of samsung and google play services?

I cant't figure out whats wrong on my end and i'm going crazy trying to troubleshoot it.

I may have found the problem.

I factory reset my phone without using smart switch and dual sim worked in google messages fine. Then one by one I started using smart switch through USB external backup and restoring my data and testing messages. It finally stopped working when I restored my text messages backups.

It appears restoring your text messages with Google messages breaks dual sim. So I factory reset the phone again and restored with everything except sms backups and it works fine now. I can live with a fresh clean plate of text messages. I'm actually happy to have RCS back now.

Just make sure you get yourself a usb-C flash drive and back up your data before factory reseting your phone. I got this one on amazon, and it worked out great https://a.co/d/eM0IImx
