So I use Freank that is a German provider, I have it, it's cheap and it works for me. They have a Andoid app that you must install and use a SIM or eSIM to make it work.
If I want to use Freank and I don't have Android, it means I can't use it or is there a way?
If that doesn't work, how do I get a cellular connection with a Ubuntu Touch phone?
I just bought a Google Pixel 3A to use Ubuntu Touch with it.
