How to block caller id on iPhone 5 iOS 7.1.1?

#1
Hi, I have tried everything but still I can't turn of my caller id. It is greyed out and it's turned on. Please help. If you have a code for Dubai, can you please give it to me? Thank you! It's really important...

It's likely a country or carrier issue. I turned off mine (USA/ATT) and called my landline. It shows as "private" on that phone. Personally, we configure our landline to block all "caller ID hidden" calls.
YMMV
