SIM failure
When I got on my phone recently I got a notification saying sim failure. I tried turning my phone off then on, I tried taking the SIM card out and putting it back in. I am just looking to get this resolved.

I recommend that you contact your carrier and try out another SIM card. You have already tried removing and reinstalling the same Card and therefore am recommending to try out a new SIM card.
