I am suddenly unable to make outgoing calls from my iPhone 4s.
I've tried resetting network settings, toggling airplane mode on and off, and all the other tricks and tips I've been able to found online. Any help appreciated. I'd call Apple or Verizon for support but I'm traveling and can't use my phone to make calls.
I haven't changed any settings on my phone - I am traveling right now and had the phone in airplane mode during my flight. It worked ONCE after that and not since.
I am able to send and receive texts AND I can receive incoming calls.
I'd be most grateful for any tips or tricks or suggestions
