Android dual-card SMS can't be sent

If you have installed a dual card, Card 1/ Card 2 can't send SMS, probably because Card 2/ Card 1 has turned on the VoLTE function and there is a network conflict. I suggest you turn off the VoLTE function of Card 2/ Card 1 and try again.

Not a single message can be sent. Maybe the message database is abnormal. You can try deleting the message and editing it again before sending it.

If you choose to prompt directly when sending a short message, you can press and hold the message of sending failure, and select more? & gt？ Check the information details ",contact the operator and feedback the error code:

If you send a paid SMS and choose "Cancel" in the prompt. After that, you can't send paid text messages, and you can't send text messages to short numbers (such as four digits). Please enter and set the operation according to the following path: enter the settings, search for paid SMS permission, and click Enter to find information. It is recommended to set it as query.

Please confirm whether you have a fixed dialing service. After starting fixed dialing, you can only send information to the contacts in the fixed dialing list, and other numbers cannot be sent. If you want to continue sending, please cancel the fixed dialing service.

If the transmission fails, the mobile phone prompts that the fixed dialing service has been opened, but the actual mobile phone has not opened this function. You can restart your phone and resend the text message.

Please back up important data to restore factory settings, and then try again. If it still can't be solved, please bring the purchase voucher to Huawei Customer Service Center for handling.
