What software does Samsung 20 14 telecom mobile phone lack? It can't receive text messages or make phone calls.

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

1. Turn off the phone again.

2. Take out the SIM card and clean the metal contacts of the SIM card with rubber. (Is the sim card in poor contact? )

3. Try to insert the sim card into this machine (regardless of whether the SIM card is aging or damaged).

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

5. Whether the attempt to update the version of the mobile phone system has improved.

6. 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.
