I'm assuming you're on Att. Contact them, you may need a new sin card

I have the same problem my s4 is also 10 days old and it says no sim card. can I bring it to samsung warranty?

This happened to me too. Went to an ATT corp. store they switched my sim and still no workie, so they sent me to the ATT repair center and gave me a new phone.

Good Luck
