Hi Guys, I've moved over from an Iphone 6 to the Samsung s7 Edge. I live in Switzerland and have a Swiss simcard which I use when I'm roaming. I travel a lot. In Switzerland I have unlimited data but when I travel I only have 1GB. On my iphone I was able to disable apps from using mobile data - this was a bit annoying as it prevented them working when I was in Switzerland as well but I was able to work with it. I've been through all the setting on the Samsung and cannot find a way to disable certain apps (like facebook for example) from using mobile data. Ideally what I would like is to be able to enable all apps when I'm not roaming but then as soon as I start roaming for certain apps to no longer be able to use mobile data. Any suggestions for this?
