Why can't Samsung note3 send text messages?

According to your description, I suggest you try the following methods:

1. I suggest you go to Settings-Applications-All-SMS-Clear Data.

2. Restart the phone to see if there is a signal problem.

3. Check whether the number of the information center is correct: Information-Menu button in the lower left corner-Settings-Information Center. The number of centers in different operators and regions is different. Please contact the network operator for confirmation. The number of the information center must be preceded by "+".

4. Try to replace another SIM card.

5. It is recommended that you try to upgrade the firmware. (Settings-More-About Devices-System Update)

If you still can't send and receive SMS through the above methods, please bring the purchase invoice, maintenance card and machine to Samsung Service Center, and the engineer will check and handle the machine. Please click the following link to find out the specific location of the service center:.

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.
