Somehow I blocked one number on outgoing calls and I cant seem to unblock it.
that number can phone me, we can text, and we can make Whatsapp calls both ways. I had my service provider have a look on the line, but no issue there.
When I placed my sim card in different phone I was able to phone the number. The 'block' is therefore not on the sim or at the service provider, but somewhere on the phone.
I am out of ideas where to look!!!
