I have an iPhone 5S, I've had it for a little over a year and a half. Lately it will say "No Service" even if I am in an area where I should have signal. I've read some online saying it is an AT&T problem and not an iPhone issue, I've tried clearing the phone and starting from factory setting and that didn't solve it, I've turned off the LTE service as I read it makes it occur more often because AT&T doesn't have much LTE coverage and the phone will always try to primarily connect to LTE and will drop signal when it cannot find it rather than resort back to 4G or 3G. It will stay in "No Service" mode for up to an hour, which is a bit of a pain. Does anyone have any tips or had any experience with this?
