Use multiple internet connections at the same time
Setting up your Mac or PC to use a 4G or 5G mobile broadband card and tethered phone connections at the same time is a very simple task. In fact, any computer running Windows 10+ or Mac OS 10+ can connect to any combination of available Internet connections. In most cases, setting up multiple Internet connections on your computer doesn’t even require any extra hardware.
If you’re trying to connect multiple Internet connections for faster speeds, note that your various connections must come from different Internet sources. For example, Wi-Fi and Ethernet networks that are connected to the same router cannot be combined for increased bandwidth using channel bonding applications like Speedify, because they both share the same upstream network.
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.

Refer to your carrier or smarthphone’s instructions to tether your phone’s mobile Internet to your computer. Here is a handy guide for tethering on most of the popular mobile broadband networks in the US.
Step 2: Connect Your 4G or 5G Mobile Broadband Card
Refer to your mobile broadband provider’s instructions to connect your mobile Internet device to your computer. If your device is a USB dongle and you’ve already installed the appropriate drivers on your computer, you can simply plug in your 4G or 5G card. For a mobile hotspot device, just connect to your computer’s Wi-Fi as you normally would.
Step 3: Combine Tethered Phone and 4G or 5G Connections with Speedify
Now that you have both tethered phone and your 4G or 5G mobile broadband network connected to your computer simultaneously, you might want to combine both for faster and more reliable Internet. This is where Speedify comes in. Speedify is a cloud service for Mac & PC users that combines all the Internet connections available to your computer to create a single fast super-connection.
To get started with Speedify, simply download and install the Speedify software, you’re ready to go. Once Speedify is running, you’ll see both the tethered phone and mobile broadband connections detected. That means you’re using both for their combined speed and reliability.
