There will be a short message about the weather forecast after Samsung answers the phone.

According to your description, you can try the following methods:

1. On the standby screen, click Applications-Settings-More Settings-Mobile Network-Network Mode-Select GSM only.

2. If conditions permit, replace the SIM card for testing.

3. (Backup data: phone book, SMS, multimedia, etc. ), I suggest you restore the factory settings.

4. It still can't be solved after the factory settings are restored. It is recommended to send the mobile phone to the nearest Samsung service center for testing and further processing.
