Message " no sim card is installed" after having installed ios 9 in iphone5i

eleni139 - I too installed iOS 9 / 9.0.2 on my iPhone 5 and I got the same message - "No sim card is installed". Were you able to find out the cause of this? For me this message didn't immediately happen right after the install. It just happened randomly a few days after the install and again today. After rebooting the phone, the cellular carrier does comes back on but what's causing this!?!

I never had this message before with any of the previously installed iOS versions. Ironically I got this same message at the same location so far - Starbucks! I can't say it's anymore than a coincidence right now since I have been to this location many other times in between without a problem. In any event, I went into "Settings" and then "Apps and iTunes Store" and turned off the "Suggested Apps" near my location switch, just in case there's a bug with location services causing the sim card to not responding. Other than that, I can figure out what's causing this.
