Unbreakable VPN Connection for iOS by Combining Wi-Fi and 4G / 5G Cellular with Speedify
An iPhone uses one internet connection at a time, so a weak public Wi-Fi slows everything down, and an ordinary VPN app squeezes all your traffic through that one weak internet connection.
Speedify is an app that combines Wi-Fi, 4G/5G cellular, Ethernet, Starlink and satellite internet connections into one faster, more reliable connection, and encrypts your traffic like a VPN. On an iPhone, Speedify hides your traffic from anyone watching the network and carries it over Wi-Fi and 4G/5G cellular at once instead of picking one. The speed and failover gains need both connections; on a single connection, Speedify works as an encrypted VPN and can be a little slower.
Speedify runs on every device you already use
The steps that follow set Speedify up on your iPhone in a couple of minutes and show what changes afterwards: your traffic on public networks is encrypted, uploads and downloads run on both internet connections, and a fading Wi-Fi signal no longer ends your call.
How to Set Up Speedify as a VPN on iPhone
- Download Speedify from the App Store on your iPhone. Speedify needs iOS 17 or later.
- Open Speedify and create a free account (the free tier includes 5 GB per month), or sign in.
- Tap Allow when your iPhone asks to add a VPN configuration.
- Keep Wi-Fi and Cellular Data both turned on in your iPhone’s settings. Speedify connects to a Speedify server automatically and uses both connections at once.
- Use your apps as usual. Speedify runs in the background and stays connected while your iPhone is in standby.
Why Use a VPN on Your iPhone over Public Wi-Fi
If you use public Wi-Fi networks with your iPhone at places like the library, restaurants or the airport, you are particularly vulnerable, because you never know how secure these networks are. One common scheme, the man-in-the-middle attack, involves someone setting up a fake Wi-Fi hotspot to trick your iPhone into connecting and then asking for login credentials. The thief captures your username and password without you noticing.
A VPN on your iPhone encrypts your traffic, so someone running or watching that Wi-Fi network cannot read it. Still, never type a password into a sign-in page you do not trust.
If Wi-Fi stops working on your iPhone when a VPN is on, a hotspot sign-in page is a common cause: the network blocks traffic until you sign in. Speedify detects the sign-in page and shows a notification, so you can sign in without turning Speedify off.
How Much a VPN Slows Down iPhone Internet Speed
Traditional VPNs do slow down iPhone internet, because all traffic goes through one connection and a VPN server. A VPN that combines internet connections, like Speedify, can make up for that when you have Wi-Fi and 4G/5G cellular turned on.
By default, your iPhone uses either Wi-Fi or 4G/5G cellular, switching between them but never using both at once. Speedify can use both Wi-Fi and 4G/5G cellular on your iPhone simultaneously.
Using both gives you faster, more reliable Internet. Speedify works in the background, monitoring the quality of your connections. With a standard VPN, if your Wi-Fi signal becomes unstable or is simply not working, you are stuck on that connection; with Speedify, traffic is automatically rerouted to 4G/5G cellular until Wi-Fi gets better, and your public IP address stays the same, so calls and logged-in apps carry on.
Speedify Privacy on iPhone: What Is Recorded and What Is Not
Speedify keeps no record of the sites you visit and does not sell personal data, but it does record connection metadata: your IP address, device ID, connection times and the amount of data used. Read the full Privacy Policy here.
Speedify encrypts your traffic with DTLS 1.2, using AES-256-GCM or ChaCha20-Poly1305, implemented with Google’s BoringSSL library.
What Changes on Your iPhone with Speedify
With Wi-Fi and 4G/5G cellular combined, you can avoid buffering issues when streaming movies, pages load faster, and your FaceTime call won’t suddenly be disconnected because of your VPN or Wi-Fi issues. Speedify works with all the apps on your iPhone (iOS 17 or later), with no extra setup per app.
A VPN on your iPhone is a good habit on any network you do not control, and with Speedify and two internet connections, that VPN does not have to slow you down or disconnect you.
