I can not make outgoing calls on my iPhone 6

I tried everything and FINALLY *#31# worked!!! Thanks so much. It's a new replacement phone and I could receive calls but couldn't make any outgoing.. Thanks so much for the help!

Another option is to simply switch off the iphone and then switch back on again. This worked fine for me when all else failed.

*#31# works

Tried even changing sim.

But once on roaming, I've not been able to make calls.

I was thinking of junking the Iphone.

But *#31# worked.

I can't make an outcall

It actually worked.

No dice. Didn't work

*#31# does work....Phewwww!!!!!!
