Unicom sent a short message to other provinces, but the other party couldn't receive it …

If the transmission shows that the transmission has been successful, there is nothing wrong with the mobile phone and the number itself. If the other party doesn't receive it, there may be many reasons, such as: 1 The other party's mobile phone is full and cannot be received; 2. The status of the other party's mobile phone is abnormal, which leads to the inability to receive it in a short time; 3. You can also send it to other friends to try. If it can be received normally, there may be a problem with the other party's mobile phone or mobile phone card; 4. If it is not received by everyone, it is suggested that you try to change the machine for testing, or you can contact the Unicom customer service with the number to assist in the inquiry.
