no sim

[Android Question]

Hi there,

My samsung galaxy s4 won't read my sim card. Could anyone shed some light of what the problem maybe

Simplest thing that could have happened - bad SIM card. (The carrier should replace it free.)

The socket could have dirt in it. (The card could have dirt on it.) The socket could be defective. The motherboard could be defective. Your carrier could just have gone out of business.

I think that's about it in order of the seriousness of the effect it will have on you.
