I do use the international dual sim version here in USA on T-Mobile.

5G almost never connects, since the version I have does not support the MM wave 5G antenna. So, pretty much stuck on 4G only.

An USB-WIFI adapter might not work, but a USB to ethernet adapter should work, if getting the device internet access is all you want.

How did you get your doctor to test you for adhd? I’m in USA, and my GP is not understanding my situation.

What android phone supports thunderbolt?

Are you me.?

I have the same situation as you have.
