Use Speedify's Pair and Share Feature to Combine Multiple Cellular Internet Sources at Once
Cellular bonding is the way to go when you need reliable Internet in any location. Whether you're traveling and working remotely or you're live streaming to your audience, fast and uninterrupted connectivity is a must.
Most solutions for cellular bonding include a dedicated hardware device you can use for this. All you have to do is put your SIM cards or tether mobile devices to the device, power it up with an external battery (or make sure it has its own battery charged) and you can benefit from the power of all mobile data connections at the same time. Such solutions are provided by companies like LiveU, Teradek, Dejero, etc. - check out a comparison of cellular bonding solutions.
However, there are also cellular bonding solutions that are software only and run directly on your device. This is the case with Speedify and in this article we're going to explain how you can use cellular bonding directly on your smartphone or mobile device with Speedify's Pair & Share feature.

4G/5G Cellular Bonding Directly on Your Mobile Device: What You Need
Cellular bonding needs at least two 4G/5G mobile data connections. So, if you want to use two cellular connections on your smartphone, you will need the following:
- two smartphones (iPhone, Android), preferably connected to different network carriers
- the Speedify Internet bonding software app
It's very simple to get things going and turn your smartphone into a cellular bonding device, whether you're just traveling and need to hop on a video call or if you're a reporter, broadcasting from the field and needing the best video quality when live streaming.
iPhone / Android Cellular Bonding Made Easy
Here's what you need to do:
- Install and run Speedify on both smartphones (iPhone / Android). Make sure you enable the Pair & Share feature when you run the app for the first time.
- Have the 4G/5G mobile data connection enabled on your smartphones.
- Connect both iPhone / Android to the same Wi-Fi. If there isn't any available, just create a personal hotspot on one of the phones and connect the other to that.
- Pair your devices from the Speedify app and you're ready to bond the two cellular internet sources.
