Why can't my Unicom card send messages?

Unicom users can't send text messages for the following reasons:

1, the mobile phone is in arrears or the balance is insufficient. It is recommended to check whether the mobile phone is in arrears or has insufficient balance.

2. Due to the limitation of frequently sending short messages or sending sensitive keywords (pornography, fraud, political short messages), according to the requirements of the Ministry of Industry and Information Technology and the group company for spam message management, the short messages that meet the interception strategy are intercepted.

3. The mobile phone doesn't have the SMS function, so it is suggested to turn on the SMS function again.

4. The SMS center number is wrong, so you need to set the SMS center number. It is recommended to check whether the SMS center number set in the mobile phone is correct first. Take the number of the short message center of Inner Mongolia Unicom as an example: +86 130 10950500.

5, mobile phone terminal problems, it is recommended to try to change the machine and change the card.

Tips: If the above methods still can't be solved, please contact the operator's customer service for inspection.
