Help-how Turn Off Main Sim??

[Elisab]

Dearst,
I've Mi4c and during the night usually I turn off the main sim (job sim with data) and I live work the second sim where I don't have plan data.
But to do this is very complicate!!
I'm obligate to switch data from main sim to second sim to turn off the main sim!!
Is there another system?
And it could be better if it possible to disable sim on the drop down menu.
What do you think about? Can you help me?
Thanks you

To my best knowledge, the only option is to set you SIM2 as primary first and then to turn-off SIM1.

Thank you very much for your answer.
I tried, but it doesn't work....it asks to me to choice the 2nd sim for data........same problem!
It seems not possible to turn off the data sim
I would like to be able choice the working sim!
It is not good!

Well, what you can do, it just to set mobile data to SIM2 and then to simply turn mobile data off. I do this way while I am abroad to use my roaming sim.
