Phone numbers getting blocked automatically in my iPhone 5C
Hi all,
I have bought iPhone 5C and it is working just fine.
But, somehow from this week it started blocking the numbers either from my contact list or from receiving calls. I tried several ways to avoid that by restoring it and by resetting the settings several times but no use. Actually, we are in a different country so I can't even contact AT&T customer care here.
What could be the issue with my phone? Is there any setting that is causing this issue? Can somebody help me out here, please? Thanks and Regards!
