How to Combine Two 4G/5G Cellular Connections at Once on Mac with Speedify

How to Merge 2 Cellular Connections on Mac

When in need for faster and reliable Internet connectivity wherever, combining two 5G / 4G / LTE cellular Internet connections on Mac is a good idea. And it’s 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 Mac at the same time. As mentioned below, for best results in terms of connection stability and speed, we recommend using two different carriers.

Speedify is the only app available for all major platforms - Windows, MacOS, Linux, iOS, Android and OpenWrt - that combines your Wi-Fi, 4G / 5G cellular, wired, and even your friend’s phone signals – and turns them into one ultra-fast and super secure link that keeps you all connected for the best possible live streaming, video calling, or just posting to your favorite app.

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 2 5G / 4G LTE Cellular Connections on Mac

Cellular connections come in various "shapes" and "sizes" when using them on your Mac computer:

  • 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 MacBooks have a built-in 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 your Mac.

Step 1: Connect Your First Cellular Connection to Your Mac

Connect your Cellular Adapter to a USB port on your Mac. Some Cellular adapters require the use of proprietary dialer software to connect to the Internet. Be sure to follow the manufacturer's installation and operating instructions closely.

To confirm your connection status, visit System Preferences, click Network, and look for your new adapter in the list on the left.

Step 2: Connect Your Second USB Cellular Adapter to Your Mac Computer

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

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.

Need to keep several devices connected in areas with limited or spotty network coverage, like event venues, remote locations or when traveling? Get consistent and uninterrupted online activity for all your devices using Speedify's Pair & Share functionality, which allows you to share cellular data between multiple devices wirelessly.

By pairing devices, you can effectively distribute your cellular connection across them, improving overall performance, especially when other network options like Wi-Fi may be slow or unstable.

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.
