Speedify Helps You Combine Wi-Fi and 4G/5G Mobile Internet Data Simultaneously
Want faster upload and download speeds and more reliable internet on your iPhone or Android phone? Run Wi-Fi and 4G/5G mobile data at the same time.
Speedify is an app that combines two or more internet connections at once – such as Wi-Fi and mobile data – so you get faster uploads and downloads and stay online if one connection drops out.
With Speedify, your internet stays on when one connection fails.
When one of your connections drops, Speedify automatically routes your traffic to your remaining connections — so calls don't cut out and downloads don't stall.
How do I use WiFi and 4G/5G cellular at the same time with Speedify?
Pick your two internet connections and your device below and we'll take you to the step-by-step setup guide.
Speedify Feature · Pair & Share
Cellular sharing that works better than a mobile hotspot.
Speedify Pair & Share: share cellular between your devices, both ways
Most hotspots give. Speedify's Pair & Share gives and takes. Two devices running Speedify pair up and each uses the other's cellular connection simultaneously, so you both get faster uploads, faster downloads, and a steadier connection. No extra hardware, no new data plans, no setup beyond a tap.

More speed
Every device you pair with adds its cellular to yours, and yours to theirs.
Stays connected
If a paired device drops out, Speedify keeps you online on the remaining links.
Always private
Every shared connection runs through AES-256 encryption. Your traffic is yours.
No new gear
Runs on devices already running Speedify, over your local network. Pair once, reconnects automatically.

Requirements

On your Android smartphone – swipe down on your notification bar and check that the mobile data toggle is switched on. Or go into “Settings,” tap “Connections,” and “Data Usage” and make sure that mobile data is switched on.
Step 2: Connect to a Wi-Fi network.
iPhone: Tap “Settings,” then “Wi-Fi,” and flip the switch on.
Android: Tap “Settings,” then “Connections”, then “Wi-Fi” and flip the switch on.

- When you launch the app, Speedify automatically detects your 2 active connections – Wi-Fi and mobile data. You’ll see them contained inside the Connection Bubbles near the top of the Dashboard.
