What a VPN actually does

A VPN, or virtual private network, sits between your device and the internet. Instead of connecting directly to a website or app server, your traffic first travels through a VPN server, which can be in another city or another country. From the outside, your connection appears to originate from that server. The practical effects are about your network identity:

Websites and apps see the VPN server's IP address, not yours.
Your traffic is encrypted between your device and the server, which matters on public Wi-Fi.
Region checks that rely on IP geolocation — some streaming catalogs, for example — read the server's country.

What a VPN does not touch is your phone's GPS. The location chip inside your iPhone keeps reading satellites and reporting your true coordinates regardless of which VPN server you connect to.

What a fake GPS app does

A fake GPS app works on a completely separate signal. Rather than rerouting your internet traffic, it changes the GPS coordinates your device reports. You pick a place on a map, and the app feeds those latitude and longitude values to iOS so that apps reading your location see the spot you chose instead of where the phone actually is.

This is the layer that maps, navigation, fitness, and most location-aware features rely on. A good location changer lets you search for a city or drop a pin, set the position, and have it apply across the device. If you want the full picture of how this works on iPhone, our Fake GPS guide walks through it.

The key difference: IP vs GPS

The cleanest way to keep these straight is to remember that a VPN and a fake GPS app change two different signals:

VPN → IP address / network location. Changes where your internet connection appears to come from.
Fake GPS → device coordinates. Changes where your phone's sensors say it physically is.
VPN affects: IP geolocation, encryption, region-locked web and streaming content.
Fake GPS affects: map position, navigation, anything that asks iOS "where is this device?"

An app can check either signal — or both. Some only look at your IP, some only at your GPS, and many cross-reference the two. That overlap is exactly why the two tools are not interchangeable.

When you need a VPN

Reach for a VPN when your goal is about your network rather than your map position. Typical cases include encrypting traffic on untrusted Wi-Fi, keeping your real IP private from the sites you visit, or accessing web content that gates access by the country of your IP address. If a service decides where you are purely from your connection, a VPN is the right lever.

When you need a fake GPS app

Reach for a fake GPS app when the thing you want to move is your physical location as apps read it. That covers testing a location-based feature you are building, previewing how a travel or local app behaves in another city, setting a consistent spot for region-specific content that checks GPS, or simply not broadcasting your exact whereabouts on the map. A VPN cannot do any of this, because none of it depends on your IP — it depends on the coordinates the device reports. To change those, you need to spoof your location at the GPS level.

Can you use both at once?

Yes, and for some goals you should. A VPN and a fake GPS app operate on independent layers, so running them together causes no conflict: the VPN handles your IP and the fake GPS app handles your coordinates. If you are dealing with a service that checks both an IP and a GPS reading, aligning the two — a VPN server in the same region as the location you set — gives the most consistent result. For most everyday needs, though, you only need the one that matches the signal you actually want to change.

Quick recap

VPN: changes your IP and network location, encrypts your traffic, does nothing to GPS.

Fake GPS: changes the GPS coordinates your iPhone reports, does nothing to your IP.

Different signals, different jobs. Pick the one that matches the location your target app is actually reading.
