My Data Guard : noRoot Firewall

When traveling, using mobile data to access the internet can be costly, but you might still need some apps to be able to connect to it, even if not all of them. You might have a smaller data plan or you would just simply like to have more control over what apps can access the internet on your Android smartphone. Whatever your motivation, setting up a firewall that does exactly this, is not very complicated.
