If you are considering installing a VPN on your android mobile phone, one cost-free option is Orbot from the Guardian Project. You can download from Google Play or GitHub.
This is effectively a proxy system which routes your mobile's data traffic over three anonymising nodes before presenting your traffic to the internet.

The first of the following three screengrabs shows the app's initial page where you start the VPN mode. Once an onion route is built to your preferred country destination [onion glows green] , all apps you have configured to use Orbot as a proxy will route over the route built. You can pick which apps route natively over your mobile provider's data network, and which route over the onion route.

In the example above I chose Iceland as the exit node country for my Brave browser's traffic. Clicking on What is my IP address? | Find my public IP address | IP.me is an easy way to test the routing delivered to the Brave browser by Orbot:
<<<<<<<<<<<<<<<<<<confirms that your browser traffic presents to the internet from an Iceland IP address range.
