How to Combine Two 5G / 4G LTE Cellular Connections on Linux

Merging 2 Cellular Connections on Ubuntu Linux

Combining two 5G / 4G / LTE cellular Internet connections might seem like a hassle or something impossible. However, it’s actually quite easy to do if you're using the right channel bonding app like Speedify.

In this guide we'll show you how you can get faster, more reliable Internet by using two cellular adapters on your Linux computer at the same time. As mentioned below, for best results in terms of connection stability and speed, we recommend using two different carriers.

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.

3 Steps to Combine Two 5G / 4G LTE Cellular Connections on Linux

Cellular connections come in various "shapes" and "sizes" when using them on Linux:

  • the most common way to connect to a cellular network is an external USB cellular adapter. For this setup, you will need two of those - one for each network;
  • some computers (especially laptops) may have a built-in 5G / 4G / LTE cellular adapter; in this case, you will only need one external USB cellular adapter;
  • you can get cellular Internet from your tethered iPhone or Android device as well;
  • you can also use a MiFi device and turn your cellular connection into a WiFi hotspot.

In this article we will assume you're using two USB cellular adapters on Linux.

Step 1: Connect the First Cellular Connection to Your Linux Computer

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 2: Connect Your Second USB Cellular Adapter to Linux

Follow the same steps as above. You should be able to see both cellular connections active in Ubuntu Linux.

Step 3: 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.
