No sim installed error

When i updated my mom's iphone 5c to ios 8.1.3 her iphone gives her a no sim installed error that flases up and goes away. Her imessages do not work and cell serivice is not working at times either. Has anyone had this problem or know what to do to fix it?

Try popping the sim out.. Reinstall, reboot the phone...

Right but I meant to activate. I swear I remember activating my phone over wifi.

It requires on to even go past the welcome screen, even my iPhone one required a sim as he explained it depends on the carrier you had

Yeah, probably just faulty memory.
