My mobile phone SHV-E 120L is a Korean version. I can't send text messages recently, but I can only receive text messages. What should I do if the number of the information center turns gray?

The model you are consulting is not listed in Chinese mainland, so we don't have relevant targeted information at present. You can refer to the relevant information of similar problem models listed in Chinese mainland.

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.
