Samsung mobile phone can't answer landline.

According to your description, I suggest you try the operation according to the following steps:?

1. Under the standby desktop-click Application-Settings-More Settings-Mobile Network-Network Operator-Search Network-Select the network operator supported by your SIM card.

2. Try to replace the sim card (regardless of whether the SIM card is aging or damaged).

3. Check whether the mobile phone is equipped with software such as security guards or incoming calls, uninstall it and try again.

4. Back up mobile phone data (phone book, SMS, multimedia files, etc.). ) and restore the factory settings.

If the problem still exists, it is recommended that you send your mobile phone to the nearest Samsung service center for testing and maintenance.
