Thank you for contacting us and sharing your concern regarding the SIM card issue on your Galaxy S23 Ultra after the recent update. We understand how inconvenient this can be and would like to assist you.

Please try the following steps:

1. Restart your device: Sometimes a simple restart can refresh network settings.
2. Check SIM card placement: Remove the SIM card, clean it gently, and reinsert it securely.
3. Test with another SIM card: Insert a different SIM card to confirm if the issue is with the card or the device.
4. Update carrier settings: Go to Settings > Connections > Mobile networks > Network operators and select your carrier manually.
5. Reset network settings: Navigate to Settings > General management > Reset > Reset network settings. This will refresh all mobile, Wi‑Fi, and Bluetooth settings.
6. Safe mode test: Restart your phone in Safe Mode (press and hold Power > tap and hold Power off > Safe mode) to check if a third‑party app is interfering.
7. Software update check: Go to Settings > Software update > Download and install to ensure you have the latest patch, as Samsung often releases fixes after major updates.

If the SIM card still does not work after these steps, the issue may be hardware‑related or linked to the update compatibility with your region. In this case, we recommend visiting a Samsung Authorized Service Center for a full inspection. You can locate your nearest center here: Samsung Service Centers.
