Which component is responsible for connecting to the mobile network?
My iPhone 5c recently started intermittently displaying “No connection” in the top left. Resetting the phone would get it to work again. But starting from this morning, no amount of resetting or re-setting network settings has fixed it. Now that I’ve done “reset network settings”, it is stuck at “Searching…” as opposed to “No connection.”
So which component is the “mobile antenna”? Is it replacable? What connections can I clean or jiggle to ensure everything is solid?
