Heading to eygpt tomorrow and dont want my nexus to try updating or connecting to tinternet unless on wifi, new to android so what do i turn off or disable ?

Pull down the notification bar thingy at the top & un-select the data option.

My Sony Xperia T has the option in mobile networks of “data roaming” – off, national or international.
Mine’s set to national and if I go abroad it won’t connect. Dunno if that is a Sony feature or an Android one.

I still turn off the mobile data symbol as well just to make sure.

Settings > More > Mobile Networks.

Turn off Data Roaming.

Settings > Data Usage > Mobile data toggle to Off. Then you should be safe enough.

Clearly I’m too slow 🙂

Ta muchly 🙂
