Iphone 6 - Removing the sim card, powering off and back on, and reinserting the sim card resolved this issue for me. I have had the same issue sevral times before and had to call my carrier to resolve. They did not give specifics but they stated this was a known issue with Iphones. Twice they had me restore my phone and then said they reset something on their end as well.
