Samsung Galaxy i9100 often fails to send text messages. Why can't I send them again? I have set up a short message report to send them. Do I know it was successful?

If the mobile phone cannot send text messages, you can troubleshoot according to the following situations:

Situation 1: The SMS center number is set incorrectly. Please reset the correct SMS center number.

1. Different mobile phone models have different setting paths. It is recommended to check the mobile phone user manual to understand.

2. Different mobile phone numbers belong to different places, and the SMS center numbers are also different. For example, the SMS center number of Shanghai Unicom is: 8613010314500, and the SMS center number of Beijing Unicom is: 8613010112500.

If there is no signal or the signal is relatively poor in case 2, you can go to a place with a stronger signal to test.

Situation 3: The mobile phone has turned off the SMS sending function. You can turn on the SMS function and try again.

In case 4, the app is included in the SMS blacklist, and you need to go to the business hall to remove the blacklist status before you can use it normally.

If the balance of number 5 is insufficient, you can pay and recharge and try again.

Scenario 6: There is a problem with the mobile phone. You can change the phone for testing.

If it still cannot be used normally after eliminating the above reasons, you can click /qAHfS to provide feedback, and we will check and deal with it as soon as possible.
