does it mean I can use both of them simultaneously?

Hi

The Mudi 7 supports Dual SIM Dual Standby (DSDS), which means both SIM cards remain in standby mode simultaneously for data connectivity.

This helps enable faster switching to the other SIM card if one encounters issues. However, only a single data connection can be established at a time, meaning only one SIM card can be used for internet access simultaneously.

Dual SIM dual standby means both SIMs can be active for receiving calls or texts, but only one can handle data at a time. So you can’t run two separate data sessions simultaneously (like one SIM on a VPN and the other routing elsewhere); you’d need to switch which SIM is handling data when you want to change.
