I used Unicom's 186 segment. Why can't the other party receive the text message sent by my mobile phone? I can accept that. ...

It's not necessarily your problem that you can't get the other person's information. You can simply judge the reasons from the following aspects:

1, if you send a text message to anyone, they won't get it. Maybe it's your phone. First, dial the local number 100 10 to ask whether the SMS sending function is enabled on your mobile phone (sending and receiving SMS is controlled by different parameters in the switching system). If there is nothing wrong with the system function, please ask the customer service staff to check the SMS center for you and see if the SMS of your mobile phone has been sent to the SMS center.

2. Do you have a "successful sending" message on your mobile phone after you send the text message? If you don't get it every time, there is something wrong with your mobile phone or system function.

3. Transposition judgment: put your card in a mobile phone that can send text messages normally. If you can't send text messages, it means that there is something wrong with your number or the system function of your mobile phone card; Put the card that can send text messages normally in the mobile phone. If this card reaches your mobile phone, you can't send text messages, which means there is something wrong with your mobile phone.

3. If a fixed person can't receive your message, but others can receive your message normally, then the problem lies in that person's mobile phone, not yours.

The above is a simple judgment. Call local 100 10, and the customer service staff will give you an accurate answer.
