By mistake, I turned sim card off in settings in sim manager on my Samsung and now it won't turn sim card back on. I turned phone off and back on and now it wont recognise my sim cards mobile number and says unknown number now. My sim still works in another phone. I have also tried a different sim in my phone and it says unknown number too even though that sim also works in another phone. Please help!

Morning
Hopefully you got this issue resolved, if not try a NETWORK SETTINGS RESET.
Thanks.
