The mobile phone was bought in Korea. You can't send a text message when you buy it, but you can receive it. I tried to install a Unicom card to send it.

The model you are consulting is not listed in Chinese mainland, and we don't have relevant targeted information at present. For similar problems of Chinese mainland listed vehicles, please refer to relevant setting methods.

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

2. Settings-Application Manager-Swipe Screen Options (All)-Find Information-Click Enter and try to clear the data.

3. Try to replace another SIM card.

4. Check whether the mobile phone is equipped with security guards or third-party SMS software, and test it after unloading.

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

If the above method still fails, please send the equipment to Samsung Service Center, and the engineer will check the machine and deal with it.

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.
