sim card error

Having the same issue as others. No SIM card notification. It's done this 2x so let's hope it stops or they push a update soon!

My manager at work got the phone the same time as me. I've been through 2 phones and 3 SIM cards, still get error every 2-3 days, sometimes several times a day. He finally got the error last week. So there seems to be no rhyme or reason when it might pop up.
 
I've had this issue for about a month, have been doing the airplane mode on, off and has worked. Occasionally had to reboot the phone.. A week ago I took the sim card out... Cleaned the card, used an aerosol air can lightly to clean the sim card slot in the phone. Haven't had the error since, I was getting it every other day before that.
