No Wi-Fi? Bond 3G/4G/5G Cellular Adapter with your iPhone for Fast, More Reliable Internet on Ubuntu Linux

Even if you find yourself in a location without any wired ethernet or Wi-Fi networks available there's no need to panic. In this article, we are going to introduce you to Speedify, the channel bonding VPN and walk you through the steps to combine a 3G, 4G, or 5G USB Cellular adapter with a tethered iPhone on your Ubuntu Linux computer.

Speedify can bond any number or combination of Internet connections and will intelligently distribute your online traffic among them for optimal performance. Plus, if you get disconnected from one of your connections in the middle of an important video call or file transfer, Speedify will seamlessly failover to your other working Internet connection(s) without skipping a beat.

NOTE: For best results, use Internet connections from different sources. In general, joining the same upstream network multiple times (such as the same router via Ethernet and Wi-Fi) will not improve performance.

4 Steps to use a USB Cellular Adapter with a Tethered iPhone on your Ubuntu Linux Computer

Step 1: Enable Personal Hotspot on your iOS device

A Personal Hotspot lets you share the cellular data connection of your iPhone or iPad with other devices via Wi-Fi, USB, or Bluetooth.

Go to Settings > Cellular > Personal Hotspot or Settings > Personal Hotspot and flip the switch to on. 
From this screen you can verify the name of the phone (which will be used as the Wi-Fi name/SSID) as well as configure the password.

NOTE: If you don't see the option for Personal Hotspot, contact your carrier to make sure that you can use Personal Hotspot with your plan.

Step 2: Connect your iPhone to your Ubuntu Linux computer via USB

Connect your iPhone or iPad to your Ubuntu computer with a USB cable. If you see an alert on your iPhone or iPad that says “Trust This Computer?” tap Trust. Your Ubuntu computer will start using your tethered iPhone or iPad and you should see it in the System Menu listed as a “Wired Connection.”
Note: It has been reported that in iOS 14, USB tethering to Ubuntu is broken. Learn More

Step 3: Connect and configure your USB Cellular adapter

Note: Before purchasing or connecting a USB Cellular Adapter, be sure to verify that it is compatible with your specific hardware and/or operating system. Some devices may require additional software or drivers from the manufacturer.

Connect your Cellular Adapter to a USB port on your Ubuntu computer. It will most likely appear in your System menu as a “Wired Connection.”

Some Cellular adapters require the use of proprietary dialer software to connect to the Internet. Be sure to follow the manufacturers installation and operating instructions closely.

Step 4: Download and Install Speedify

Last but certainly not least, download and install Speedify. Once running, Speedify will automatically detect any available Internet connections and combine them for increased speed, security, and stability.

You can manage settings, view statistics, and even apply limits to individual connections by either clicking/tapping on them from the Dashboard or by navigating to the desired connection through the main Settings menu.

Speedify will work quietly in the background to optimize performance including prioritizing streaming web traffic to avoid stuttering, buffering and disconnects.

Whether at home, work, or on-the-go, Speedify is the only VPN that makes your online experiences faster, more reliable, and more secure.
