"Service is currently Unavailable" when making calls
I have Samsung Galaxy Note 4 that I've had for about 2 weeks, and I haven't been able to make any calls. I just receive the service is currently unavailable message. I ported my old number and it's update on the FP account. I've restarted my phone several times, installed proper updates, and followed the troubleshoot guide. Does anyone know why this is happening and how I can fix it?
