Hello syauqi12.
I don't have that phone but in searching for an answer I saw an older support thread at Sony for a sim card problem seemingly like yours and they had some suggestions that you might try. I hope this is helpful.
Main: No Sim Card in Phone
If this happened after running an update it may be worth running a repair to reload the firmware in case something went wrong when the last update was being applied:
To repair the phone software
1. Install PC Companion on a Windows PC from Support at Download for PC - Sony Smartphones (Global UK English)
2. In PC Companion, under Support Zone and click Start.
3. Under Phone Software Update, click Start.
4. Click repair phone.
5. Follow the on-screen instructions.
