Speedify Combines Wi-Fi and 4G/5G Mobile Data Simultaneously Instead of Switching Between Them
Tired of slow or unreliable Internet? Have you ever wondered if it's possible to use the mobile data connection on your iPhone AND a Wi-Fi connection at the same time? It's easy to combine Internet connections on iPhone with Speedify.
We're not talking about switching between connections - Wi-Fi, Ethernet, cellular dongle, etc. We're saying you can use all your available connections simultaneously on your iPhone. That's great news, as your connection will get faster and more stable. Your smartphone will be able to harness both the download and upload bandwidth of your connections, Wi-Fi and mobile data.
Wondering how to combine Internet connections on iPhone? It's simple: you need a software channel bonding / link aggregation solution that will unlock the potential of your smartphone.
Quick answer
Should you have a backup 4G, 5G, Starlink, or cable internet connection?
Yes — every internet connection goes down, including Starlink, which drops for ~34 minutes a day on average. A backup connection from a different provider means one outage never takes you fully offline. The most common options are a 4G/5G cellular hotspot, a cable or DSL line, or a second satellite dish.
4G/5G cellular
Works anywhere. Just a SIM or hotspot — no installation needed.

Speedify Feature · Pair & Share
Speedify Pair & Share: share cellular between your devices, both ways

What Are the Benefits when You Combine Internet Connections on iPhone?
Most people are OK with their iPhones automatically switching between Wi-Fi and cellular data, as needed. But there's a problem: this switching takes time, at least a few seconds.
So what can happen during those seconds, you ask? Here are some examples:
- you may lose an important idea during your video calls
- you may be required to log in again to a particular platform or work VPN you're using, because the IP address of your device has changed with the switch. This means additional time.
- you may be booted from the online game you're playing
- you may lose your unsaved work in the cloud
... and the list can go on.
By combining Internet connections on your iPhone, you get more reliable connectivity. Your session will be consistent - meaning that your IP will not change if Wi-Fi should fail, because you'll still be connected to cellular data. That saves a lot of time and hassles.
Faster Internet is also a benefit when you combine Internet connections on iPhone. You can create a "super-pipe" from your Wi-Fi + cellular data connections.
This will help with bandwidth-intensive apps like live streaming, video calls, online gaming, remote learning, etc.
All of this (and more!) is possible with the Speedify channel bonding app.
