The time is now 5:07PM, and apparently my phone has not had any kind of service for an hour or so now. I have an iphone 4S, and I attempted to reboot the phone and/or reset the cell service. However, I still receive an error message of no service. Furthermore, my co-worker has an iphone 5, and his 4G LTE also has zero bars. Any idea if this could be verified or resolved?
