The drop didn't work....the other fixes did not work. What worked was shutting the phone down...taking either the sim chip remover or a paper clip and gently putting it in the sim card slot and sliding it back and forth...gently across the contacts for the sim card. The phone came right back up and has worked perfectly since. Guessing the contacts became corroded and/or dirty....and from my perspective..it is a fix that actually makes sense....lol
