I have no service on my Iphone 4s. I had service this morning but as soon as 830 am hit, I lost service. I paid my bill and I don't have any other network to connect to on my carrier networks. Can you please help me? I am in the St. Catharines/ Niagara Falls area.
I am going to suggest a hard reset. Hold the power button down and the homescreen button down together at the same time. Watch the device power off and the apple icon to appear. Let the icon disappear. Then wait about 30 seconds and power the device on only holding down the power button at the top right. This should fix it. Let us know. :)
