Finally got my GSMT SIM yesterday with 240. I put it in my I535 and USCC variant S2 and it didn't connect, so do I need to change something in my account? I checked the map and it says there is still 2G in my area. Or do I need to give it time to connect?

My 3310 clone from Aliexpress's battery expanded but I have a fake Galaxy S8 that supports 2G so I could test it in there too. It worked on Mint when I tried it. I don't remember it getting disconnected unlike my 5s which was instantly removed.

I accidentally ordered a GSMA SIM not knowing that AT&T isn't the greatest in my neighborhood and I remember T-Mobile being a lot faster. How can I switch to a GSMT network and still have a physical SIM? The network switch section of the app only gives me the option to use eSIM.
