Why can't Huawei dual-card mobile phones send text messages?

1, please confirm whether the SIM card has passed the authentication of the operator's real-name registration system. If the information when handling the SIM card does not match your ID card information, there may be problems such as abnormal signal, inability to make phone calls, inability to send and receive short messages, and inability to access the Internet for data services. I suggest you consult the operator's customer service for real-name registration system certification.

2. Please check whether the SIM card is in arrears, and the suspension of arrears will affect the mobile phone communication.

3. Please confirm whether the number of the SMS center is set correctly. Please consult the operator for details.

4. Please check whether there are sensitive words in the short message, or send short messages to the same number repeatedly, which will be blocked by the operator. Please consult your local operator for details.

5. Please check whether there is a blacklist in the mobile phone housekeeper, which causes the message to be intercepted and cannot be received. If so, please delete the number from the blacklist and try again.

6. When the cell phone has no signal or the signal is weak, the information may not be sent successfully. Please try again where the signal is strong.

7. The network system is busy, especially during the peak period of holiday information transmission, and the information transmission may be unsuccessful. It is recommended to avoid the rush hour and try again.

Remarks: If the above methods can't solve the problem, it is recommended that you back up important information, restore factory settings or upgrade your mobile phone system and try again.
