No Sim Error on iPhone 5S at iOS 9.2.1

[tchios_1]

I have iPhone 5S which is running at iOS 9.2.1, since sometime it has been playing up with the sim card. It sometimes says No service and then suddenly said No sim. And now it completely says No sim. Is there any solution to this problem or do I have to wait for iOS 9.3 update?

I've been getting the same message on an iPhone 5 running iOS 6. Possibly just an issue with either hardware or SIM card.

I'll try using sim card of another carrier then update you.

Carrier 1 gives error No Sim
Carrier 2 gives error No Service but it is searching for network and giving carrier options.

What should I assume for this?
