Why can't vivo smartphones send short messages?

You can check the troubleshooting methods for not sending MMS:

1. Try to switch to the traffic network, close the 5G network or change to another location;

2. Replace the SIM card and resend it;

3. Confirm whether the content of the multimedia message is too large. If the content of MMS takes up more memory, it can be sent several times;

4. Enter Settings-Applications and Permissions/More Settings-Application Management, and find the information to clear the data and cache before sending it;

5. After backing up the data, go to Mobile Phone-System Management/More Settings-Backup and Reset/Restore the factory settings, and restore all settings. This operation will not delete the data in the mobile phone, but will restore all the settings in the mobile phone, including the set wallpaper, unlocking method, WiFi, default opening program, etc. And the third-party software account registered in the mobile phone needs to log in again.

If the above methods are not effective after operation, you can take your mobile phone and purchase voucher to the customer service center for testing and processing. The address of the customer service center is: enter the service outlet of the vivo official website /vivo Mall APP-mine-or the webpage of vivo official website-slide to the bottom-service support-service outlet inquiry-select provinces and cities to inquire the address of the customer service center. It is recommended to call in advance before going to avoid empty running, plan your trip reasonably and travel safely.
