The Setup Process
I ran into a real headache last month when configuring a PPTP VPN on a Samsung Galaxy S22 running Android 13. The system would accept the credentials, the connection would establish briefly, and then it would drop every single time. The log message was vague — just a failure to complete the LCP negotiation. After about forty minutes of testing, I figured out the issue wasn't the credentials or the server. It was the MTU setting on the VPN profile itself. Android 13 defaults to an MTU that doesn't always play nice with PPTP's GRE encapsulation overhead, which eats about 24 bytes per packet. I changed the MTU to 1396 manually in the VPN profile, and the connection stabilized immediately. This is the kind of detail nobody tells you about in the official documentation. Here is how you actually get it working. Open Settings and navigate to Network and Internet. Tap VPN, then add a new profile by selecting the plus icon in the top-right corner. Choose PPTP/IPSec XAuth PSK as the type. Enter your server address, username, password, and if your setup requires it, the pre-shared key. Save the profile and tap it to connect. That is the basic path. In practice, you will probably need to adjust settings after the initial attempt fails. Android 13 tightened permission handling compared to older versions. When you tap the VPN profile, the system will prompt you to confirm the connection through a dialog. This is normal. The dialog does not block anything — it is just Android's security layer asking for explicit consent before routing all your traffic through the tunnel. If the dialog does not appear, check that you have not disabled VPN permission in the Security settings under Advanced.
The server address needs to be correct. PPTP uses port 1723 for the control channel and GRE protocol 47 for the data tunnel. Some networks block GRE at the firewall level, which means the connection will appear to work but your actual data never passes through. If you are behind a restrictive corporate firewall or a poorly configured router, try switching to a different server or a different port if your VPN provider supports it. PPTP itself does not support alternative ports natively, so your provider would need to handle that at the server side. I also want to flag something most guides skip over. PPTP has known cryptographic weaknesses. The MS-CHAP v2 authentication method it relies on has been cracked with publicly available tools. If you are using this on a public Wi-Fi network, you are getting convenience, not serious security. A modern OpenVPN or WireGuard setup would give you actual encryption strength. PPTP's main remaining use case is legacy compatibility — older routers, cheap VPS hosting panels, or environments where the infrastructure simply cannot be upgraded. Know what you are signing up for before you start routing sensitive traffic through it. Download-wise, you do not need a separate app from the Play Store for the basic VPN client. Android 13 includes the PPTP VPN handler in the OS. Any third-party app claiming to be a PPTP VPN client for Android is either bundling its own tunnel interface or misrepresenting what it does. If your VPN provider offers an app, it might handle the configuration for you, but the underlying protocol remains the same and the same limitations apply.
If you want to verify your connection is actually working, open a browser and visit a site like whatismyipaddress.com. Check that the IP address shown is different from your home IP. Then run a speed test. PPTP typically adds between 10 and 30 percent overhead depending on your base connection and the server distance. If you see a drop of 50 percent or more, something is misconfigured — usually the MTU issue I described earlier, or the connection is falling back to a much slower server. One more practical note. Android 13 may warn you about the VPN having full network access. This is expected and not a bug. The VPN app needs access to read and route your network traffic. Denying it will break the tunnel. Also, if you are using a custom ROM or a device with manufacturer skin modifications — Xiaomi, Huawei, OnePlus — the VPN settings may be buried under additional menus or restricted by battery optimization features. Disable aggressive background restrictions for your VPN app if connections drop while the screen is off. If PPTP consistently fails on your device or network, the honest recommendation is to move to WireGuard. It is faster, lighter, and the implementation in Android 13 is built into the kernel. PPTP has its place, but it is a depreciating one. Setting it up works fine if you account for the MTU adjustment and understand the security tradeoff. Beyond that, the setup itself is straightforward enough that it should not take more than five minutes once you know where to look.
