If your Samsung smartphone is displaying "unknown" for the phone number in the "About Phone" section and you're unable to add or edit the phone number through the SIM card settings, here are some steps you can try:

1. Check SIM Card Insertion:
Ensure that the SIM card is properly inserted into the phone. If the SIM card is not detected or inserted incorrectly, it may not display the phone number.

2. Restart Your Phone

3. Update Software:
Ensure that your phone is running the latest software update. Software updates often include bug fixes and improvements. Go to Settings > Software update > Download and install.

4. Check SIM Card Information:
Go to Settings > Connections > SIM card manager. Verify that the SIM card is recognized and active. Some carriers provide an option to edit or add the phone number directly from this menu.

If the issue persists and you are unable to add or display the phone number through the SIM card settings, it's recommended to contact your mobile carrier's customer support. They may be able to assist with any carrier-specific settings or provisioning.
