When we are at home and we want to connect to the Internet with our smartphone, we always choose WiFi connectivity for its speed and low latency, in addition, we do not have any type of limit as it happens with many 4G and 5G data rates that we have today.However, when we go away from home we have the possibility of connecting with our data rate or to a public WiFi.Today we are going to explain what it is for you to have a VPN on your mobile when you are away from home, since there are two types of VPN that you can use.If we set up a VPN server at home, either on a NAS server or directly on our router, we can connect with our smartphone from anywhere as if we were at home.Thanks to setting up a VPN at home, we have the possibility that all the traffic from our smartphone, whether through the mobile broadband network or public WiFi, goes through an encrypted and secure tunnel to the server, and a Once you're here, go online through our home Internet connection.This type of VPN is widely used for the following cases:As you can see, using a VPN server at home and connecting to it provides us with many advantages and strengths.If you don't have one yet, we recommend reading our OpenVPN setup tutorial and also setting up WireGuard VPN at home.If we don't install and configure a VPN server at home, then we can use third-party VPN services like Cloudflare's WARP VPN, a totally free VPN that works really well.Third-party VPN services do not allow us to access our local home network, print remotely, or share files and folders, but they do encrypt all communication end-to-end to protect our privacy and security.This type of third-party VPN is widely used for the following cases:As you can see, we have two very different uses of VPNs installed at home and third-party VPNs, in both all traffic is encrypted and authenticated, using different protocols such as IPsec, OpenVPN or WireGuard.If we want to access resources at home, you will have to install a VPN server on the router or NAS, but if you just want to browse safely, bypass blocks and filter malicious content, a very good way to do it is to use a third-party VPN.
