Ever since updating my IPhone 5C to iOS 8 I haven't had any service. The first day I could send texts but couldn't receive them, and now it says "No service" Regardless of where I am in my home or outside, I can use wifi but that's all. I have restarted my phone, put it on airplane mode, turned my phone on an off, and also went to general and reset the network. Non of the options have worked and no one seams to be able to help. I've never had trouble with my IPhone up until now, please help.
