What if vivox20 can't send a text message?

The mobile phone can't receive text messages or text messages of certain numbers. We recommend that you:

1. If it's an official SMS from an operator, a bank or a group purchase, please try to resend it, check the status of your sim card, and restart your mobile phone to receive it again later.

2. If it is a verification code, it is recommended to change to another location and try to send and receive it again to rule out whether it is caused by network reasons.

3. Change other time periods to receive again.

4. Verify whether the SMS blacklist function is set in the mobile phone: information-more-settings-blocked information-blacklist/whitelist/blocked phrase/blocked information-view (different mobile phones may operate in slightly different ways).

5. Check whether the mobile phone has downloaded the latest third-party software (security guards, system management). It may be that the software intercepted the message, so I suggest you try to uninstall it.

6. Try to replace another SIM card.

7. If not, please back up your mobile phone data (phone book, SMS information, multimedia materials, etc.). ) and restore the phone factory settings.

8. Check whether the SMS center number is correct.

If the problem still exists, please contact the local manual customer service for further processing.
