Hello,

I want to disable the data connection (3G/4G) for my second sim card but I have no idea how. I can only select the default sim for calls and internet, but not disable it completely.

Anyone have an idea on how to do this? I'm running MIUI 9.5

Default sim for internet=the one that has 4G and data. The other one is 3/2G only and has no data enabled. Data can be disabled completly from the fast toggle in notification area or from settings.
