Use Speedify’s Pair and Share Feature to Combine Multiple Cellular Internet Sources at Once
You can do cellular bonding on an iPhone or Android phone with no extra hardware, by combining the 4G/5G cellular connections of two or more phones. Traveling in a group? Here is how to combine coverage from two phones.
Speedify is an app that combines two or more internet connections at once, such as the 4G/5G cellular from two phones, so you get faster uploads and downloads and stay online if one connection drops out. With only one internet connection, Speedify works as an encrypted VPN and cannot make that connection faster or stop it from dropping.
Speedify uses every internet connection your device has, at the same time

Combining 4G/5G Cellular Directly on a Phone: What You Need
Cellular bonding means combining two or more 4G/5G cellular connections into one faster, more reliable connection. To combine two cellular connections on your smartphone, you need:
- two smartphones (iPhone, Android), preferably connected to different network carriers
- the Speedify app, which combines internet connections
Setting up two phones to combine their 4G/5G cellular takes a few minutes, whether you’re traveling and need to hop on a video call or you’re a reporter broadcasting live from the field and need the best video quality.
How to Combine 4G/5G Cellular from Two Phones with Speedify
Here’s what you need to do:
- Install and run Speedify on both smartphones (iPhone or Android). Turn on Speedify’s cellular sharing feature (labeled “Pair & Share” in the app) when you run the app for the first time.
- Turn on 4G/5G cellular on both smartphones.
- Connect both phones to the same Wi-Fi network. If no Wi-Fi network is available, create a personal hotspot on one phone and connect the other phone to it.
