How to disable mobile data for one of the sim I have a OnePlus 2 and have 2 sims in it. My question is how can I keep Mobile Data for SIM 1 on and off for SIM 2?

I have tried options in SIM and network settings but option to enable/ disable mobile data is in general setting and not in SIM specific settings.
There will be an option in Sim and Network settings mentioning "Default Sim for Internet". Choose the SIM 1
