Iphone 6s says no sim card?

All of the sudden I woke up and my phone said No Sim. So I held down the power and home button to see if it changed and then it changed and then all of the sudden it says No Sim again. I'm trying to pop open the sim tray with a paper clip and it won't budge. I think I got a little bit of it stuck in there. I'm just confused, i'm a 15 year old girl so i'm not Tech. Savvy

Try this 1. Go to Settings 2. Tap on General 3. Tap on Reset 4. Then tap Reset Network Settings---This should solve the issue
