I cannot make calls from my I phone6

Hi Have you made sure your Simcard is inserted correctly Also try a reboot press & hold power button & menu button hold both down until You see Apple Logo . If you still have a problem contact your network provider . Cheers Brian

There could be several reason why you cannot make a call. Perhaps you can provide more information. What happens when you try to make a call? Do you get any error messages? If you do please post them exactly here.
