Mobile phones can't send and receive text messages.

1. Samsung's inability to send short messages is not due to the lack of payment, but to the number setting of the information center. The specific solutions are as follows:

1, click the information in the mobile phone to open it;

2. Open the SMS menu interface, click the expand icon in the upper right corner, and then click Settings;

3. Click on the message;

4. Click on the information center;

5. Enter the SMS service center number provided by the local network provider (China Mobile/China Unicom), and then click OK.

Second, Samsung's mobile phone can't receive SMS, which is generally a system ROM problem or a mobile phone arrears. Operate according to the following methods:

1. Edit a short message on your mobile phone and send yourself a try.

2. Try to change another SIM card to receive SMS.

3. Back up the data in the mobile phone (contacts, text messages, pictures, etc.). ), and then try to restore the factory settings (Settings-Reset/Privacy-Restore Factory Settings).

4. Check whether software programs such as mobile phone security guards are installed in the mobile phone. If there is an uninstall attempt, please check whether there are any restrictions on installing third-party software.

5. Enter the SMS settings to see if the SMS limit has been reached. If yes, please increase the quantity. By the way, check whether other settings have been clicked. Press the menu button again and choose to restore the default settings to try. (SMS setting entry method: click SMS, and then click the menu key of mobile phone in the SMS interface. Select settings. )

If all the above methods are ineffective, there may be something wrong with the internal program. I suggest you take the three-guarantee certificate of your mobile phone and send it to the nearest Samsung service center for engineers to check the machine.
