Another user recently posted about what seemed to be the same issue but on a different phone. I'm posting because although support has been super responsive, friendly, and easy to talk to they didn't provide a long term solution after checking my area signal strength. Perhaps someone here has one.

I'm on a pixel 7. Using a physical non warp network card.

When I exit my home and become out of range of my home wifi my phone seems to fail at switching to the USMobile sim network for connection. I didn't ever experience this while previously on T-Mobile.

Another time it happens is when I connect to a known wifi signal briefly, like at a Starbucks, and I leave the area and it fails to connect to us mobile.

I used to throw my phone into airplane mode for a second and then turn it off and that used to fix this problem. But recently it takes 15-30 mins to reconnect.. I try restarting my phone, I toggle the SIM on/off, location, 2G, refreshing the Internet connection icon, just toggling whatever I can think of to get it back. I usually keep my wifi manually off when I leave the house now but when I forget to and I lose USMobile connection getting it back has been super frustrating recently.

One thing I found that worked today was toggling " automatically select network" to off and I saw USMobile with options for LTE and 5G and picking LTE made it connect to that then I selected 5G and it connected to that.
