Improve Bandwidth and Reduce Latency on Ubuntu by Combining a Tethered iPhone with a 4G/5G USB Cellular Dongle
Want faster upload and download speeds and more reliable internet on Ubuntu Linux? Run a 4G/5G USB cellular adapter and a tethered iPhone at the same time. Speedify is an app that combines two or more internet connections at once – such as a 4G/5G cellular adapter and a tethered iPhone – so you get faster uploads and downloads and stay online if one connection drops out.
Speedify uses every internet connection your device has, at the same time
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.
How do I use WiFi and 4G/5G cellular at the same time with Speedify?

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
Step 3: Connect and configure your USB Cellular adapter
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 manufacturer's 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.
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.
