Does a VPN used on a smartphone with Wi-Fi disabled (mobile data only enabled) provide any sort of protection? (beehaw.org)

I've never completely understood this, but I think the answer would probably be "no," although I'm not sure. Usually when I leave the house I turn off wifi and just use mobile data (this is a habit from my pre-VPN days), although I guess I should probably just keep it on since using strange Wi-Fi with a VPN is ok (unless someone at Starbucks is using the evil twin router trick . . . ?). I was generally under the impression that mobile data is harder to interfere with than Wi-Fi, but I could well be wrong and my notions out of date. So, if need be, please set me straight. 🙂

I would still recommend turning wifi off when leaving home for privacy reasons (which can easily be automated). The process to identify if a network is trusted or not requires a handshake. So leaving wifi on makes you trackable by the wifi network operators and the apps on your phone with access to your wifi, wether you connect a network or not.
