Samsung Note3 N9009 card 2 mobile phone number is not in service area when dialing, so it is impossible to make and receive calls and send and receive short messages normally.

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

1. Under the standby desktop-click Applications-Settings-More Networks-Mobile Networks-Network Operators-Search Networks-Select the network operators supported by your SIM card.

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 replace the sim card (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. 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.

It is recommended that you apply for "booking to the store" in Samsung official website and enjoy priority maintenance service:/pre-order.

After the appointment is successful, please bring your machine, invoice and warranty card to the service center you reserved on time.
