Want faster upload and download speeds and internet that stays online even if one connection drops out? Run Wi-Fi and a tethered phone at the same time.
Speedify is an app that combines two or more internet connections at once – such as Wi-Fi and a tethered iPhone or Android’s 4G/5G – so you get faster uploads and downloads and stay online if one connection drops out. It works on Windows and macOS.
<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.

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

Adds redundancy and throughput for remote sites or heavy usage.

Step 1: Connect to Wi-Fi
Just connect your Mac or PC to Wi-Fi like you normally would using your computer’s internal Wi-Fi card.
Step 2: Tether Your Smartphone
Refer to your carrier or smartphone’s instructions to tether your mobile internet connection to your computer. Here is a handy guide for tethering on most of the popular mobile broadband networks in the US.
Step 3: Combine Tethered Phone and Wi-Fi with Speedify
Now that you have both Wi-Fi and your phone’s tethered 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 application. (Speedify is currently available on PC, Mac, Android and iOS) Once running, you’ll see both Wi-Fi and tethered phone connections detected. That means you’re using both for their combined speed and reliability.
