That being said, your data gets chopped up into packages for transmission even without a VPN. The difference is that a VPN connection repacks it to keep you safe, and encryption overhead helps the server reconstruct that structure after description. Just how big the overhead is depends on the VPN protocol in use. Generally, the more secure protocols incur a larger overhead.
It’s typically said that, depending on the protocol, you can expect a 5-15% increase in data use, with the biggest glutton being OpenVPN working in TCP mode.

What VPN protocol is best for mobile data?
The simple answer is IKEv2 but let’s take a closer look.
- PPTP: uses the least data. However, that also makes it the least secure. By now, it’s pretty outdated and should be avoided in general;
- OpenVPN TCP: often considered the most secure protocol. However, it also consumes a lot of mobile data and can be a bit slower than the others;
- OpenVPN UDP: faster than and just as secure as TCP. The connection may be less stable but not enough that it would hinder what you’re doing. A decent option;
- WireGuard: the newest security protocol. Uses very little mobile data and is very fast. A great option for anyone;
- IKEv2: our winner. Great at conserving mobile data. Fast, efficient, and has no issues dealing with network changes.

There are a few ways you can minimize VPN data usage:
-
Use split tunneling
Split tunneling (Bypasser on Surfshark) allows you to make exceptions for which apps use VPN protection. For example, you can choose to encrypt everything except your Steam account. In this case, Steam would not have an encryption overhead because it’s not encrypted. That way, apps you do not want to protect will not use data.
-
Turn off the VPN when not in use
When you don’t need the VPN to hide your IP and encrypt your data, you can turn it off. Of course, we recommend keeping the VPN on all the time, as you never know where threats lurk. Still, if you’re not using your phone for a bit, you might want to turn your VPN off to reserve data.

Avoid free VPNs

There are many reasons you shouldn’t use free VPNs. One of them is data usage. As free VPNs often stay afloat by showing you ads and pop-ups, you will likely end up using more data. Loading these ads and pop-ups takes more resources than loading a regular VPN app.
Get your mobile VPN right here
Now that we’ve established that a VPN works over cellular data and that it impacts data usage, you should start thinking about getting a VPN for your phone. With that in mind, ensure your security and privacy with a VPN service that cares about mobile users too.
