Why my sim card not work

Most likely cause is your iPhone is locked to a particular
wireless provider. If this is the case, only that wireless provider
can unlock it. Ask them if they offer unlocking and if you qualify.
Look at Settings>General>About and scroll down to Carrier Lock.
If the iPhone is unlocked, it should say 'No SIM restrictions'.
If you get a different answer, the iPhone is locked.
