There could be several reasons why your phone can't read your SIM card. Some troubleshooting can help identify the cause:
1. Try restarting the phone.
2. Try turning the phone off, removing the SIM card, re-inserting the SIM card, and turning the phone on again.
3. Try using a pencil eraser to clean the gold contacts of the SIM card in #2.
4. Try inserting the SIM card in the a different phone.
5. Try asking for a replacement SIM from your mobile service provider (if applicable).
6. Try performing a soft reset; or a hard reset.
7. Try taking your phone to a service center.

All these details will help us narrow down the probable cause of the problem.
