Better Internet, Anywhere & Anytime!
Want faster upload and download speeds and more reliable internet, wherever you are? Run two or more connections – such as Wi-Fi, 4G/5G cellular, Ethernet or Starlink – at the same time. Speedify is an app that combines two or more internet connections at once, so you get faster uploads and downloads and stay online if one connection drops out.
This guide shows which internet connections you can find at home, at work or on the road so you always have at least two to combine.
With Speedify, your internet stays on when one connection fails.
When one of your connections drops, Speedify automatically routes your traffic to your remaining connections — 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.
Learn more →Second Starlink
Adds redundancy and throughput for remote sites or heavy usage.
Learn more →Speedify bonds any two connections into one — automatic failover, more speed, no dropped calls.
