Wireless Cellular Bonding on Your iPhone
The more connections you bond, the faster and steadier your Internet, and cellular is the one connection you can get almost anywhere. Combining ten cellular connections used to mean a rig of phones tethered to USB hubs feeding one laptop, and only that laptop benefited.
Speedify's Pair & Share feature makes it far simpler: pair up to ten phones over the local network and every paired device shares and receives cellular both ways, so they all get the faster connection.
Quick answer
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.

Best for fixed locations. Different network, so outages rarely overlap.

Adds redundancy and throughput for remote sites or heavy usage.

Speedify Feature · Pair & Share
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.
Learn how Speedify's Pair & Share works ›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.
Pair & Share Ten Cellular Internet Connections to Your iPhone
To combine 10 Internet connections at once, you will need the Speedify app, which is available for iOS, Android, MacOS, Windows and Linux. Speedify lets you combine any number of Internet connections for better performance by using channel bonding technology to intelligently spread traffic between connections.
Speedify's Pair & Share functionality enables you to combine multiple personal hotspots together to increase internet upload and download speeds for everyone! It's a new kind of hotspot and this means that:
- no cables are needed
- all paired devices can use the shared devices' cellular Internet connections
So it's not just one device that can benefit from faster, more reliable Internet, but multiple ones.
The only requirement to use this feature is that all devices should be on the same local network. If there isn't an accessible public Wi-Fi network to connect to, one of the devices can create a personal hotspot. All other devices can connect to it and then follow the steps to pair and share.
3 Steps to Combine 10 Cellular Internet Connections on an iPhone
What you need
- 9 smartphones for 9 cellular connections - better if they run on different cellular networks
- one Wi-Fi network - either public or created by one of the phones
- the Speedify app installed on all smartphones.
Steps to bond 10 cellular connections
- Connect all smartphones to the same Wi-Fi network
- Run Speedify and pair devices between them
- Share the cellular connection of each of the 9 smartphones
... and you're all set! Now you can livestream, work remotely or do whatever Internet intensive tasks you want on a faster and more reliable connection. And it's not just you who can do that - every other paired device will benefit from this.
Your Bonded Cellular Connection Is Also Secure
Pair & Share is built with security in mind. Only the people you trust will be able to pair & share their Internet connections with you.
- You only pair with devices after you give permission. You can stop sharing at any time
- All traffic between the devices on the local network is encrypted
- All your internet traffic is encrypted on your device, so that only the Speed Server can decrypt it. This means that even if you're sending your web browsing and email through someone else's phone's Cellular, there is no way for that person to read or change any of your data
- We do not upload, who you paired or shared with, what sites you visited, or the name of your device to our servers, or any third party.
