I have an iPhone 7, and for some reason my iMessages intermittently won't go through. When on the phone, people can't hear me what so ever. And forget about any sort of web browsing or apps that require data, they all time out. These issues are not consistent, but more often then not I have anywhere from 3-5 (full) LTE bars of service when it happens. At first I thought maybe my phone was trying to connect to a weak WiFi signal that was slowing everything down, but I've turned off WiFi and am still having the same issues.
Anyone have any suggestions?
