Hi there Shane. Please do the following in this order; Turn phone off and remove SIM card. Leave the SIM out and turn phone back on. Go to Settings > General > Reset > Reset Network Settings. On the dial pad, enter ##25327# and press call. A message no SIM or resetting Subscriber Settings will appear, wait until the network reset finish. Replace the SIM and reset the network settings one more time. Go to Settings > General > Reset > Reset Network Settings and reset again. On the dial pad, again enter ##25327# and press the start call button. Let’s see if that work.
