Merge Two Mobile Data Connections from Two Smartphones for One Fast, Stable and Secure Internet
Speedify gives you faster, more reliable internet when traveling in a group by combining the mobile data from two phones on different carriers at once. Speedify is an app that combines two or more internet connections at the same time into one faster connection, so a weak signal from one carrier is backed up by the other.
If one phone’s connection drops, Speedify keeps you online on the other. Speedify runs on Windows, macOS, Android, iOS, and Linux.
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.
How to Combine Coverage from 2 Smartphones to Get Stable Internet
Requirements
- your smartphone with an active mobile data connection (iPhone or Android)
- a second smartphone with an active mobile data connection to provide the second connection (iPhone or Android)
- the Speedify bonding VPN app
We’ll assume that you’ll be combining the coverage from the 2 phones on your smartphone.
Step 1: Set up a mobile hotspot on the second smartphone (your friend’s phone).
On an iPhone, go to the phone’s connection settings and tap “Personal Hotspot” to enable a mobile hotspot. Set the hotspot name and password and flip the switch on.
On an Android smartphone, go to the phone’s settings area – “Connections” and search for “Mobile Hotspot and Tethering”. Set up the hotspot’s name and password and enable it.
Step 2: Make sure the mobile data connection is active on your phone.
If you have an iPhone, tap “Settings,” then “Cellular,” and flip the switch on.
If you’re using an 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 3: On your smartphone, connect to the other phone’s hotspot.
On an iPhone, tap “Settings,” then “Wi-Fi,” and flip the switch on. Select the other phone’s Wi-Fi network from the list that appears.
On an Android smartphone, tap “Settings,” then “Connections”, then “Wi-Fi” and flip the switch on. Select the other phone’s Wi-Fi network from the list that appears.
Step 4: Time to start combining the coverage from the 2 smartphones on your phone!
- Download Speedify from the App Store or Play Store.
- 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.
- Select the server you want to connect – usually the “fastest” option works best
You can now return to your usual activities without having to worry that the Internet will be slow or disconnect. If your friend provided the second connection, make sure you pass him your phone from time to time. He also deserves to enjoy the fast, stable and secure Internet connection on your phone.

- stay safe from hackers and snooping ISPs, especially when connecting to public WiFi networks
- bypass content restrictions on certain networks, in certain areas or countries and unblock video streaming services.
- avoid ISP data throttling for certain services like Twitch and YouTube.
