Learn about why mobile data of SIM 2 is being used when sending or downloading MMS while you have chosen to use data traffic of SIM 1 as default.

Applicable for all realme smartphones.

You will need to select a SIM card to send or download MMS even if you have chosen to use the data traffic of SIM 1 in [Setting] > [Dual SIM & Cellular].         

For example, if you have selected SIM 2 to send an MMS (Multimedia Messaging Service - which is  a standard way to send messages that include multimedia content to and from a mobile phone over a cellular network.), the MMS will be sent / downloaded with the mobile data of SIM 2. It will automatically switch back to the mobile network of SIM 1 when the MMS is sent / downloaded.

This is the design of Android system, not a malfunction of your phone.
