Hey there amirul40,
Welcome to Apple Support Communities.
If I understand correctly, there was an issue entering the SIM PIN on your iPhone 5 which has created an issue activating and using your device. The article below provides troubleshooting tips for several iPhone activation issues, including the Invalid SIM message that you described.

If you see a No SIM card error, follow these steps. No SIM or Invalid SIM alerts appear when a SIM card is damaged, locked, or missing.
