How Speedify Uses Two 4G/5G Cellular Adapters at the Same Time
Speedify combines internet connections, using every connection available in macOS instead of switching between them. In this case, Speedify lets you use 2 cellular adapters at the same time on your Mac, for faster downloads and uploads and a steadier connection.
You get more bandwidth, so your apps run faster. Speedify runs in the background and keeps checking the quality of your connections. With auto failover, when one cellular connection drops or has a weak signal, Speedify routes all traffic through the other one until the first connection is restored. All of this happens automatically, and you most likely will not notice anything.
Speedify also provides advanced encryption like a VPN, without forcing you to give up speed or reliability. Speedify works on Macs running macOS 11.5 or later. Check the current system requirements on the download page.
4 Steps to Use Two 4G/5G Cellular Adapters at the Same Time on a Mac
Here is how to combine two 4G/5G cellular dongles on a Mac computer or laptop. You can also use tethered Android smartphones or iPhones instead of cellular adapters: the idea is to use two cellular networks at the same time. Android USB tethering on a Mac needs HoRNDIS, which works only up to macOS 10.14 Mojave, so an iPhone is the easier choice on a current Mac.
- Connect the first USB cellular adapter to a USB port on your Mac, as shown in Speedify’s guide to connecting a 4G/5G dongle to a Mac. Some cellular adapters need the maker’s own dialer software to connect to the internet, so follow the manufacturer’s installation and operating instructions closely.
- Connect the second USB cellular dongle to your Mac.
- Confirm your connection status: open System Settings (System Preferences on older macOS versions), click Network, and look for your new adapters in the list.
- Get Speedify from the App Store. Once running, Speedify will automatically detect any available Internet connections and combine them for increased speed, security, and stability.
