Speedify Combines Starlink and a Tethered Android Phone on Ubuntu Linux for Faster Uploads and Downloads and a More Reliable Internet Connection
You can share your Android phone’s 4G/5G cellular connection with your Ubuntu machine by tethering it via USB. Speedify then bonds that tethered Android connection with your Starlink Wi-Fi simultaneously, using Speedify’s channel bonding technology. Both internet connections carry your internet traffic at the same time, giving you faster upload and download speeds, automatic failover, and encrypted internet traffic.
This guide explains why a tethered Android phone is a practical cellular backup for Starlink on Ubuntu, how Speedify manages both internet connections, and how to get set up in three steps.
Why Tether an Android Phone Alongside Starlink on Ubuntu Linux
Starlink and your Android phone’s 4G/5G cellular data use entirely separate infrastructure. Starlink connects through low-Earth-orbit satellites. Android’s cellular data connects through ground-based carrier towers. A weather event or satellite issue that disrupts Starlink does not affect your phone’s cellular connection. A tower outage does not affect Starlink.
For Ubuntu users who already have an Android phone, USB tethering turns that phone into an immediately available second internet connection. No additional hardware subscription is needed beyond your existing mobile data plan. Plugging in via USB also keeps your Android phone charged while it provides the tethered connection to your machine.
With Speedify running on your Ubuntu machine, both Starlink and the tethered Android phone carry your traffic simultaneously. If Starlink drops during an active SSH session, download, or VoIP call, Speedify reroutes all traffic through the tethered cellular connection without interrupting the session.
How Speedify Manages Starlink and a Tethered Android on Ubuntu
Once USB tethering is active on your Android phone and your Ubuntu machine is connected to both the tethered interface and Starlink Wi-Fi, Speedify detects both connections and begins monitoring them. Speedify tracks latency, packet loss, and available bandwidth on each path every few milliseconds.
When both connections are healthy, Speedify distributes traffic across both and delivers up to 95% of their combined upload and download capacity. When one connection degrades, Speedify moves all traffic to the healthy connection at the packet level. Sessions stay live.
Speedify also encrypts all your internet traffic across both the Starlink and tethered Android connections, protecting your data on every path.

How to Combine Starlink and a Tethered Android Phone on Ubuntu Linux with Speedify
Step 1: Enable USB Tethering on Your Android Phone
On your Android phone, go to Settings > Connections > Mobile Hotspot and Tethering and enable USB Tethering. Connect your phone to your Ubuntu machine using a USB cable. Ubuntu should recognize the Android phone as a new network interface automatically. Run ip link or check Network Manager to confirm the tethered interface is active.
Step 2: Connect Your Ubuntu Machine to Starlink Wi-Fi
Using your built-in Wi-Fi interface, connect to your Starlink network via Network Manager. Confirm both the Starlink Wi-Fi and the tethered Android interface are active and assigned IP addresses.
Step 3: Download and Run Speedify
Download Speedify for Linux and install it on your Ubuntu machine. Speedify will detect both connections and begin bonding them automatically. No manual routing configuration is needed.
Speedify manages both connections in the background from that point: combining them for faster upload and download speeds, monitoring both paths, failing over instantly, and encrypting all traffic.
