Hi there!
2 days in after the switch from IOS to Android Fairphone, and I’ve noticed that my sim card becomes unavailable every time I put the phone in charge! This is rather annoying and counter-intuitive: I cannot be contacted when the phone is charging… Surely this is not right?
Cheers,
benjamin
Hi Benjamin and welcome to the dark side - or is it the other way round? 
Sorry to hear that you should have to face this problem from the beginning. As you suspect, this behaviour is definitely not right. I can see that you’ve found an old thread where two other FP owners have reported the same - sadly without any information if/how their problem was solved. But it’s highly uncommon. I suggest (as Joe did in the other thread) that you contact FP support.
