ADSL and 4G/5G Bonding – No Need for Dedicated Router
Need a faster ADSL connection? Don’t have access to any other form of broadband Internet that is faster (cable, fiber)? Then we recommend using your mobile phone’s 4G LTE / 5G cellular data connection together with your existing ADSL. This will get you a faster and more secure Internet connection when you need it.
Read below our easy step-by-step guide to combine an ADSL Internet connection with a 4G LTE / 5G cellular connection on your Windows PC or Mac computer. We are using Speedify, a bonding VPN that can combine two or more connections together.

Living in remote areas “in the middle of nowhere”, as some might say? Or, sadly enough, don’t you have other alternatives to your ADSL Internet connection where you’re located? You can still make the best of it and use your phone’s Internet link together with your existing ADSL line. It’s very easy to combine them with our Speedify software app.
Requirements
- A subscription of Speedify bonding VPN. Speedify can be used on both Windows and macOS computers, as well as Android, iOS and Linux.
- A 4G LTE / 5G connection – this may be your mobile phone or a USB cellular dongle.
6 Steps to Combine ADSL and 4G LTE / 5G into a Fast, Stable and Secure Internet Connection
Here’s what you have to do:
- Make sure you’re connected to your ADSL Internet, either via wired Ethernet or Wi-Fi. For best results, we recommend using the wired Ethernet connection, as Wi-Fi signal is variable.
- Setup your 4G LTE / 5G cellular connection: either tether your smartphone via USB or connect a USB cellular adapter. See instructions below on tethering:
- Start Speedify and log in using your subscription credentials. Speedify will detect your active ADSL and 4G LTE / 5G Internet connections and show them on the screen.
- Choose a server for Speedify to connect to and combine the DSL Internet link with your tethered phone connection. By default, Speedify will connect to the fastest server, but you can choose a specific location as well, if you need to unblock restricted content.
- Set the 4G LTE / 5G cellular connection on a Secondary priority and specify a daily or monthly data cap. You don’t want to exceed your quota and pay more, so Speedify will just cut the use of the tethered phone data connection once you’re done for the day / month.
However, if you have an unlimited data plan, feel free to set the 4G LTE / 5G cellular connection priority as “Primary”. - Enjoy faster Internet with Speedify, as it combines your ADSL Internet link with your 4G LTE / 5G cellular connection for their aggregated bandwidth and speed. When both symbols light up in the Speedify interface, that means they’re connected and online, and Speedify is bonding the two.
