Combine Two or More Cellular Internet Connections While Live Streaming or Working Remotely
Want faster upload and download speeds and more reliable internet , even when you only have cellular? Combine two or more 4G/5G connections at the same time on your Windows, Mac or Linux computer.
Speedify is an app that combines two or more internet connections at once – such as two 4G/5G cellular connections – so you get faster uploads and downloads and stay online if one connection drops out.
<1 sec
With Speedify, your internet stays on when one connection fails.
When one of your internet connections drops, Speedify shifts your traffic to your remaining connections in under a second — so calls don’t cut out and downloads don’t stall.
Should you have a backup 4G, 5G, Starlink, or cable internet connection?
Yes — every internet connection goes down, including Starlink, which drops for ~34 minutes a day on average. A backup connection from a different provider means one outage never takes you fully offline. The most common options are a 4G/5G cellular hotspot, a cable or DSL line, or a second satellite dish.
4G/5G cellular
Works anywhere. Just a SIM or hotspot — no installation needed.

Reasons to Combine Multiple 5G / 4G Cellular Connections
Combining multiple Internet connections at once is a great idea anytime. You can use any mix of wired Ethernet, Wi-Fi and cellular to get fast and stable Internet connectivity. But why would you only combine 5G /4G LTE cellular connections?
Here are some common scenarios:
- you’re live streaming outside of your studio or home (IRL streaming included);
- you’re working remotely on the go, from a public place, bus, train, etc.
- you’re into the events business, live streaming weddings, church services, birthdays, etc.
- you’re a vlogger who likes to go live from anywhere.
Whatever the reason, cellular services are available almost anywhere in the world and offer you the best coverage compared to the other types of connections.
3 Steps to Combine Multiple 4G/5G Connections (Cellular Bonding)
Requirements
- A computer running Windows, MacOS or Linux. Alternatively you an also use devices like a Raspberry Pi – as long as they run one of the operating systems mentioned above.
- Two or more cellular connections, preferably from different carriers. These include:
- smartphones and other mobile devices with cellular
- MiFi devices
- external USB 5G / 4G cellular adapters
- built-in internal cellular network adapters
- Speedify – the only app that can combine multiple Internet sources into one bonded super-connection for more stable and secure live streaming, video calling, and web browsing.

Step 3 – Run Speedify
Speedify should recognize all your internet sources and combine them all together at once once you connect to a server. Yes, it’s that simple!
Why Speedify Is the Best Solution for Cellular Bonding
Speedify is an app, it’s software based, it runs directly on your computer or mobile device. Cellular bonding solutions from LiveU, Peplink or others require expensive dedicated bonding hardware.
Also – Speedify uses channel bonding (link aggregation) technology, and not load balancing – here’s an article to compare the two.
As a result of the technology used, Speedify also provides a secure way to connect to the Internet, using advanced VPN-grade encryption. So you also stay safe from internet snoops, unblock restricted content and bypass ISP throttling.
As a conclusion – Speedify not only allows you to combine multiple 4G connections at once on your computer. It’s a real building block for any type of internet bonding you have in mind – whether it’s your own broadband bonding router or just an essential connectivity piece on your computer and mobile device.
