IPhone 5s running 9.3.2. Intermittently I'll get a message no sim card installed when in fact there is one installed and my phone still works. I've restored my phone and set it up as a new phone and I notice I still got the message. This has happened twice. Any ideas? The only thing I hadn't tried was taking the card out and putting it back in. To do that do I need to straighten the paper clip or keep it like normal?
