Why can’t Huawei nova4 send text messages?

If you are using a Huawei mobile phone, you can do it through the following methods:

1. "Enhanced message" cannot be sent

The text message editing box displays "Enhanced message" Message", it means that the mobile phone is using enhanced information to send text messages. If your mobile phone's "enhanced message" cannot be sent, the number may be controlled by security policies or the network is unstable.

1. Please go to SMS>Three Dots/Four Dots>Settings>Enhanced Information, turn off and on the Enhanced Information switch again and try.

2. If it is still not resolved, it is recommended that you consult your operator.

Note:

1> Enhanced information is a service customized by China Mobile operators. China Unicom and China Telecom do not currently support this service. Please refer to the actual situation.

2>The enhanced information menu can be displayed only when the main card is a China Mobile card. The main card is a non-mobile card and cannot use this function.

If the type of text message is "normal text message", please continue troubleshooting.

2. Some text messages cannot be sent

For example, if you send a text message to an operator (China Mobile 10086, China Telecom 10000, China Unicom 10010), if it is sent successfully, it means that the mobile phone is a partial text message. Unable to send.

1. If the text message contains sensitive words, the other party cannot receive it after sending it

Please use test statements to send text messages to confirm whether it can be received normally, such as hello, thank you, goodbye, etc. . If it can be received normally, it means that the text messages you sent before may contain sensitive words, and it is recommended that you avoid sending sensitive words.

2. Please confirm whether the fixed dialing service has been turned on

After turning on fixed dialing, messages can only be sent to contacts in the fixed dialing list and cannot be sent to other numbers. If you want to continue sending, please cancel the fixed dialing service:
