vpn not working on 4g

Is your VPN not working on a 4G network?

Don’t worry.

It’s a common issue that many users face. In this guide, I’ll show you why this happens and give you six easy ways to get your VPN up and running again.

Why is your VPN not working on a 4G network?

Your VPN isn’t working on 4G mainly due to slow internet speed, unoptimized device settings, or technical issues on your ISP’s side.

Here are some common causes that might be affecting your VPN connectivity on 4G networks.

  • Network restrictions: Some mobile carriers have restrictions that can interfere with VPN connections. These restrictions might block certain types of traffic or VPN protocols. 
  • VPN protocol compatibility: VPNs use different protocols to create a secure connection. Some of them may not be fully compatible with your 4G network, leading to connectivity issues. For instance, users often complain that Point-to-Point Tunneling Protocol (PPTP) is blocked on Verizon 4G and only works correctly on Wi-Fi.
  • Signal strength: A weak or unstable 4G signal can disrupt the VPN connection. VPNs require a stable internet connection to maintain a secure link.
  • Configuration errors: Incorrect settings within your VPN app or your device’s network settings can lead to VPN not working correctly on a 4G network.

Now that you know the causes behind your connectivity issue, let’s see how to fix them:

How to Fix Your VPN When It’s Not Working on 4G

If your VPN isn’t functioning correctly on a 4G network, you can fix it by adjusting your VPN settings, improving signal strength, or switching to a more compatible VPN service. 

Follow the steps below to troubleshoot and resolve VPN errors on 4G networks:

1. Check your network restrictions

Reach out to your mobile carrier to inquire if they have any restrictions on VPN usage over their 4G network. Meanwhile, some data plans might have limitations that affect VPN connectivity. Ensure you have a working internet plan with sufficient data.

2. Switch VPN protocols

Sometimes, a low-encryption VPN protocol like PPTP is blocked by cellular internet providers. Here’s how you can change the VPN protocol from your app.

  1. Open the VPN application on your device.
  2. Look for the settings or configuration menu.

  1. Select a different VPN protocol. Options include OpenVPN, IKEv2, WireGuard, Lightway, etc. Each protocol has its strengths and might perform differently on your 4G network.

3. Improve signal strength

You can improve your internet speed by moving your device to a better location or resetting your 4G network. 

A VPN often affects your internet speed. Therefore, try to move to an area with stronger 4G coverage. It would resolve any connectivity issue if the problem lies with the network strength. Try to avoid places with known signal issues, like basements or remote areas.

While this is not a permanent solution, it’ll tell if signal strength is at fault. Similarly, a network reset can also help you improve the connection speed. You can put your device in the Airplane mode for a few minutes to reset the network. Turn off Airplane mode to see if the issue is gone.

4. Update and reset your VPN app

You should update your VPN app if it’s not working on a 4G mobile network.

App developers frequently issue updates to patch security and performance issues. Therefore, you should always keep your VPN up to date

Meanwhile, try resetting the network configurations if you are already running the app’s latest version. You can quickly reset it by deleting the app’s data and cache:

  1. Go to device settings.
  2. Search for the VPN app.
  3. Look for storage information.

5. Switch VPN servers

The VPN server you’re currently connected to may be overly crowded or even down due to technical issues. In such cases, connecting to a different one can fix your 4G connection. 

Here’s how to do it quickly:

  1. Open your VPN app.
  2. Select a server from the list of countries.
  3. Hit the Connect button.

You should connect to a physically close location for the best results.

6. Change your VPN provider

Now, if none of the above methods work, it’s time for more drastic measures. In some cases, your current VPN service may simply be incapable of providing a solid connection on 4G.

So, switching to a better one is your next move.

I’ve prepared three services that offer stellar performance no matter the circumstances. Let me give you more details on each one of them:
