There are two things causing this problem,either your phone is not registered to the Sim card's network or your Sim card is corrupt
To find out where the problem has come from,you should try another Sim with your phone, if the Sim does not work then the phone is registered to a particular network and no other Sim card will work on it.
If you try another Sim card and it works then your Sim card is corrupt and you should replace it.but to be double sure,test the Sim card on another phone to see if it works,if it does then your phone is not compatible with the Sim card's network but if it does not work then your Sim has to be changed
