My phone has started completely losing cell signal mostly while im out driving. When it happens it says "no sim - searching" then it reconnects says tmobile. Then does the whole thing again. This will happen repeatedly over and over. Software is up to date. I switched from reg Sim to Sim to attempt to fix the problem. Still same. Sometimes putting on airplane mode for 1 or 2 min will stop it. But that could be coincidence.
