I have an iPhone 5 and I have not been having any LTE connectivity issues up until today. My phone says "no service" and then searches, and only connects to 3G. I flip the LTE switch off and it remains connected to 3G, as expected. However, when I flip the LTE switch on again, it says no service, as if there is a problem with LTE on the cell tower itself. I normally have 4 bars LTE where I am. Yes, I've reset my network settings and rebooted my device. If I venture out of town I get LTE, so I know it's not a problem with my device's antenna. Area of concern is Orangeville, ON.
