Improve Bandwidth and Latency by Combining Tethered iPhone with a 4G/5G Cellular USB Dongle on Windows
The quest for faster, more reliable Internet is never ending. If you’re in a spot without Wi-Fi Internet but have a 4G LTE / 5G USB cellular dongle together with your trusty iPhone, you can use them together at the same time on your PC. This will get you faster, more reliable Internet.
All you need is a channel bonding (or link aggregation) software app like Speedify. In this article, we are going to walk you through the steps to combine a 4G LTE / 5G dongle with a tethered iPhone simultaneously on your PC.
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.

Combine multiple internet connections to fix slow Internet
Speedify is the only app that seamlessly combines all of your connections, including WiFi, 4G, 5G, Ethernet, and Starlink, into one stronger connection to keep you online and secure.
In most cases, Speedify will automatically detect and start using any available Internet connections on your device while intelligently distributing your online traffic between them for optimal performance. If you need help we have quick start guides available for most common set ups.

Combine personal hotspots for better bandwidth and signal strength
Speedify's Pair & Share is a feature that enables you to connect to multiple hotspots at the same time and wirelessly share LTE, 4G, and 5G cellular connections back and forth between multiple Speedify users on the same local network to create a faster, more reliable connection for everyone.
For the first time, it's possible to share cellular data between multiple devices, including PCs, Macs, iPhones and Androids. Use multiple phones as hotspots for internet access and get increased bandwidth and mobile failover for all paired devices.
4 Steps to Combine a 4G LTE / 5G Dongle with a Tethered iPhone on a PC Using Speedfy
Step 1: Connect your USB Cellular Adapter to your PC
Connect your Cellular Adapter to a USB port on your PC. 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.
In order to verify that your cellular connection is active, click on the computer / Wi-Fi icon in the lower right area of the taskbar (systray) and check to see if a “Cellular” tile shows up.
Step 2: 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 3: Connect your iPhone to your PC via USB
First, be sure to install or update to the latest version of iTunes, it contains the drivers needed to enable USB tethering.
Connect your iPhone or iPad to your PC with a USB cable. If you see an alert on your iPhone or iPad that says “Trust This Computer?” tap Trust.
Make sure that you can locate and view your iPhone or iPad in iTunes. If your Windows PC doesn't recognize your device, try a different USB cable.
Your iPhone should automatically start sharing its connection to your PC. If you click on the network icon in the lower right corner of the taskbar, the iPhone should be listed at the top of the network list.
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.
