Why is there a red exclamation point in the middle of the message?

A red exclamation mark appears when texting. There was no successful reminder because the information was not sent out. Generally, it is because the mobile phone network is not good, which leads to the failure of sending text messages or the card is loose. Either the other party blacklisted you, and the information you sent was rejected by the other party.

In these cases, you may wish to turn off the phone first to see if the card is in poor contact. If the contact is poor, use an eraser a few times before connecting it. If there is nothing wrong with the card, turn it off and on again to see if the mobile phone network is normal and whether the mobile phone is in arrears. If the above two situations are not available, then it is likely that the other party refuses to answer. At the same time, you can also call the customer service phone of Telecom and ask what is going on. China Mobile calls 10086 for manual service, China Unicom calls 100 10 for manual service, and China Telecom calls 10 for manual service.
