Lumia 535 Dual-SIM, Windows Phone 8.1, OS Version 8.10.14234.375.

I have noticed that infrequently my mobile data gets enabled automatically even when I had turned it off earlier.

In Store and Feedback I have set to WiFi-only. Is there anything else I have missed?

Go to Settings -> mobile+SIM or cellular+SIM for some users as noted in comments.

Change the option "For limited Wi-Fi connectivity" to "don't use mobile data" from "use mobile data".

    In my phone there is no setting as mobile+SIM but as cellular+SIM I wonder how come it differed unless you have different OS and Model. Anyway Thank You! :)

    I think it depends on your regional settings. It should be "mobile + SIM" for British English and "cellular + SIM" for American English.
