Speedify is an app that combines two or more internet connections at once, such as a DSL line and a tethered phone’s 4G/5G, into one connection and encrypts your traffic like a VPN.

Make DSL Internet Faster with a Tethered Phone’s 4G/5G Cellular Connection

If you live in a remote area, or DSL is the only wired internet where you live, you are not the only one stuck with a slow line. You can still get more out of DSL internet by using your phone’s 4G/5G cellular connection together with your existing DSL line. Speedify combines the two in a few minutes.

Requirements

  • Speedify, the app that can combine multiple connections into one faster, encrypted internet connection, with a free account or a Speedify subscription.
  • Your phone’s USB cable for tethering, which is usually the same cable you use to charge it.

7 Steps to Combine a DSL Line with a Tethered Phone Using Speedify

  1. Download and install Speedify on your Windows PC or Mac computer. Sign in with a free account (5 GB per month), or purchase a monthly or yearly subscription.
  2. Connect your phone to your computer with the USB cable by plugging it into an empty USB port. Make sure the operating system detects the phone and installs the correct drivers for it. On Windows, an iPhone needs Apple’s drivers, which come with iTunes or Apple Devices. On a Mac, many Android phones tether with no driver: in the Mac’s Network settings, uncheck “Disable unless needed” for the phone’s network, and turn the phone’s Wi-Fi off. If your Android phone does not show up, plug the Mac into the DSL router with an Ethernet cable and join the phone’s Wi-Fi hotspot instead.
  3. Turn on tethering in your phone’s settings: USB tethering on an Android phone, or Personal Hotspot on an iPhone.
  1. Start Speedify and sign in with your Speedify account. Speedify will detect your active DSL Internet connection and your tethered phone connection and show them on the screen.
  1. 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 also pick a specific country or city from the server list. Any Speedify server also helps you reach sites your network blocks.
  1. Set the tethered phone connection to Secondary priority and set a daily or monthly data cap. Speedify stops using the tethered phone once it reaches the cap, so you do not pay for going over your plan. If your phone has an unlimited data plan, consider setting the tethered phone connection to “Primary” priority instead.
  1. Enjoy faster internet: Speedify combines your DSL line with your tethered phone connection and uses the bandwidth of both. When both connections light up in the Speedify interface, they are online and Speedify is combining them.

Speedify Does More Than Get You Faster DSL

Speedify is more than a way to use and manage DSL and tethered phone internet connections together on your computer. Speedify is also a mobile VPN platform built for speed, so the encryption costs little of the speed you gain by combining connections. Speedify encrypts all of your traffic, which protects you on an unsecured public Wi-Fi network.

Speedify is also available for iPhone, iPad, Android smartphones and tablets from the App Store and Google Play. One Individual subscription covers up to 5 devices at once.

Speedify keeps no record of the sites you visit and does not sell your data to other companies.

Speedify improves your device’s internet connection and makes it more secure, in one app that anyone can use.

If you need faster DSL internet, tether your phone to your computer and combine the two internet connections with Speedify. Get started with Speedify today with a free account that includes 5 GB per month.
