Can you someone tell me what is this?
I mean... It almost says what it is in the pop up.
You can get further information inside of the roaming "app" or whatever this actually is in this case.
Or simple - this is roaming, with OnePlus powering it, more or less. You can get roaming over a data plan, which is ridiculously expensive in most countries, and get some good plans in others. If you have two sim cards installed, one will be disabled while enabling.
I think this is the same as "E-SIM".
