Help How to switch data use with dual sims?

[NWEwalker]

Hi, please can anyone tell me how to switch data use between two sims. One plus 3 phone is using one sim only for data use and consequently the other sim has zero data use. Also can this be made automatic so that when the limit on one sim is reached the phone automatically switches to the other sim?

Bumping this. Lollipop let you choose. I can't seem to find out how to do it in M.

Thanks McrRed. It does seem a bit stupid to offer a dual Android SIM phone and then have no apparent way to switch data use between the SIM for data use when you can do that with SMS and calls, albeit recognising that you might not be able to use both simultaneously in various circumstances. Ideally, setting a data limit for each SIM with the phone switching from a full data use SIM to the other SIM at the appropriate time would be what would work best for users.
