Combine 4G/5G Cellular with Wired Ethernet to Increase Bandwidth and Lower Latency on iPhone
Want faster upload and download speeds and more reliable internet on your iPhone or iPad? Run 4G/5G cellular and wired Ethernet at the same time.
Speedify is an app that combines two or more internet connections at once – such as 4G/5G cellular and Ethernet – so you get faster uploads and downloads and stay online if one connection drops out.
With Speedify, your internet stays on when one connection fails.
When one of your connections drops, Speedify automatically routes your traffic to your remaining connections — so calls don't cut out and downloads don't stall.
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?

Speedify Feature · Pair & Share
Cellular sharing that works better than a mobile hotspot.
Speedify Pair & Share: share cellular between your devices, both ways
Most hotspots give. Speedify's Pair & Share gives and takes. Two devices running Speedify pair up and each uses the other's cellular connection simultaneously, so you both get faster uploads, faster downloads, and a steadier connection. No extra hardware, no new data plans, no setup beyond a tap.

More speed
Every device you pair with adds its cellular to yours, and yours to theirs.
Stays connected
If a paired device drops out, Speedify keeps you online on the remaining links.
Always private
Every shared connection runs through AES-256 encryption. Your traffic is yours.
No new gear
Runs on devices already running Speedify, over your local network. Pair once, reconnects automatically.
3 Steps to Combine Mobile Data and Wired Ethernet at the Same Time on Your iPhone
Step 1: Make Sure the 4G / 5G Cellular Data Connection Is On and Working
Verify that you have an active mobile data connection on your iPhone or iPad, and that you have your data turned on.
Go to Settings > Cellular and flip the switch to on.
Step 2: Connect Wired Ethernet to Your iPhone
In order to use an Ethernet connection on your iPhone or iPad, you’ll need a compatible Ethernet adapter.
IF YOUR DEVICE HAS A LIGHTNING PORT
You can use either a Lightning to USB3 adapter in conjunction with a USB Ethernet adapter or alternatively a dedicated Lightning to Ethernet adapter.
IF YOUR DEVICE HAS A USB-C PORT
You can use any USB-C Ethernet adapter or a USB-C hub that includes Ethernet.
Plug the adapter into your device and connect an Ethernet cable to it and your router or modem.
To double-check your Ethernet connection is working, go to Settings > Ethernet (on iOS devices this menu is hidden unless there is a compatible Ethernet adapter detected)
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.
