Unicom SMS permission

Unicom's failure to send short messages may be caused by the following reasons:

1, the mobile phone is normally turned on, and it may be impossible to send short messages when it is in arrears or actively turned off;

2. The number of SMS center in mobile phone is incorrect, and the number of SMS center in each region is different. For example, the SMS center number of Tianjin Unicom mobile phone card is+8613010130500. If you are a Unicom mobile phone card from other provinces and cities, you can call the Unicom customer service department to which your mobile phone card belongs for consultation.

3. The SMS sending function of your mobile phone card is not enabled normally. You can use this machine to call the Unicom customer service hotline 100 10, and ask the Unicom staff to help you check whether the SMS sending function of the mobile phone card is enabled normally. You can't send a short message due to the failure of the mobile phone terminal. You can put your mobile phone card on the mobile phone of your family or friends and try it to see if it can send short messages. If you can, it means that it is a problem with the mobile phone terminal, and you need to contact the mobile phone terminal for after-sales consultation. If it cannot be sent, you can contact Unicom's customer service hotline 100 10 for consultation.
