I tried that app. Not surprisingly, it tells me that it doesn't work with android 12.
I bought my phone "used like new" from Amazon. It's unlocked and has the T-Mobile logo when I turn it on. It came with android 10 when I got it. I checked for updates and it updated to 11 right away. I never even got to see what 10 was like. I regretted that immediately. I got this phone with the intention of signing up with Mint because my old one wouldn't work with Cricket any longer once they required phones that supported VoLTE. It had 11 on it before I got Mint. It ran fine with 11. After 12 I noticed things that were odd. They've had a couple security patches since the update, the last was Sept 1st, plus I had it repaired in the beginning of August. It was fairly recently that I started to realize that I kept missing calls. I figured that it was because my phone is always in a bag and I just wasn't hearing it. But then I noticed that it made no notification sounds. I wear Bluetooth headphones all day at work and all the sounds come through those. I wasn't missing anything at work, and I didn't think much about it at home. I also have a tablet and any notification sounds came through that. As I said... my phone is used 98% of the time as an audio player. If I've missed anything, let me know.
It sure would be good if that other sim card worked in your phone, and I really appreciate you trying.
