I want to add an e sim on my S21 5G but its not working,
me and my friend have same brand and he got it working on his samsung.
I noticed that I have android 11, and I can't get the latest software update, any ideas how to get it?
We tried it on another phone and it was working, so I believe the problem here is that I need to have my android software version updated to 12. But I still didn't get it
