Why can't oppo smartphones send MMS messages?

Failure to send and receive MMS normally may be caused by the following factors:

1, first check whether the terminal is a MMS mobile phone, and then check whether the settings are normal; If the setting is not normal, set the MMS phone correctly;

2. Whether the MMS has been successfully sent or received;

3. If GPRS is enabled and the status is "MMS client", check whether the local network is normal; At present, MMS service is generally carried by GPRS network, and WAP and other services are used to judge whether the local GPRS network is normal. If the GPRS network is abnormal, you need to call 10086 in time to report it to the local staff.

4. If the GPRS network is normal, there may be problems with WAP gateway, MMS center (MMSC), photo album, mailbox and website. You can call 10086 to report the problem to the local staff.
