My s3 will only make and receive calls within 5 miles of my home in Illinois. While traveling over the past weekend I was able to use the phone in Zanesville, OH. But nowhere inbetween. When dialing a number the phone will not connect and after 20 or 30 seconds I see the call ended message. All incoming calls go directly to voicemail.
I have done a soft restart and cleared the data cache.
