More specifically for Note 4.
Will be traveling later in the year in Asia, so I thought it would be better to subscribe to a VPN service just in case.
After a quick 10 minutes of googling, Express VPN and Pure VPN come up a lot, I don't know if they are really good or they spend a lot on marketing. It seems $10/month is the norm, but I also came across VPN Unlimited which is only $2/month. Price is not a huge factor since only needed for a couple of weeks, ease of use and reliability would be far more important.
Any recommendations?
Also I'm a little bit confused about setting up the VPN, is it a matter entering some settings into More Networks > VPN? Or does it require a dedicated app? But some sites also suggest you need to root the phone?! I don't need anything overly sophisticated or over the top secure, I just need some added security and also to use Facebook and Google (Gmail, YouTube, etc.).
I have never used VPN on phone, is it correct to assume once a VPN connection is established, all native apps will use the VPN connection by default and there's no need to mess about with individual applications?
Cheers!
You don't need to root your phone to use VPN and yes you are correct that all native apps will use the VPN connection.
The best VPN depends on what you want. Do you want privacy to be a must, are you fine with the VPN operator keeping logs of what you accessed or are you just after a VPN to access certain websites
