Solved! Phone shows no network sign

[morpheuskay]

My samsung galaxy s4 wont show whether im connected to a network or not. When i check mobile networks within the phones setting,it shows `insert sim card`.
what could be the problem?

Shut down your phone, remove the sim card and reinstall it. Power on again.

If it doesn´t show up, maybe the SIM card is faulty.
