Merge Two Mobile Data Connections from Two Smartphones for One Fast, Stable and Secure Internet
When you travel with someone on a different carrier, you can merge the internet of two phones: Speedify combines both smartphones’ 4G/5G cellular connections on one phone for faster, more reliable internet. Speedify is an app that combines two or more internet connections at the same time into one faster connection, so when one carrier’s signal is weak, the other carries the traffic.
If one phone’s connection drops, Speedify keeps you online on the other. Speedify runs on Windows, macOS, Android, iOS, and Linux.
Speedify combines whatever connections you can find on the road
How do I use WiFi and 4G/5G cellular at the same time with Speedify?
Pick your two internet connections and your device below and we'll take you to the step-by-step setup guide.
How to Combine Coverage from 2 Smartphones to Get Stable Internet
Requirements
- your smartphone (iPhone or Android) with 4G/5G cellular turned on
- a second smartphone (iPhone or Android) with 4G/5G cellular turned on, ideally on a different carrier, to provide the second internet connection
- the Speedify app
These steps combine the coverage from the 2 phones on your smartphone.
Step 1: Set up a mobile hotspot on the second smartphone (your friend’s phone).
On an iPhone, go to the phone’s connection settings and tap “Personal Hotspot” to enable a mobile hotspot. Set the hotspot name and password and flip the switch on.
On an Android smartphone, go to Settings > “Connections” and look for “Mobile Hotspot and Tethering”. Set up the hotspot’s name and password and turn it on.
Step 2: Make sure your phone’s 4G/5G cellular connection is turned on.
If you have an iPhone, tap “Settings,” then “Cellular,” and flip the switch on.
If you’re using an Android smartphone, swipe down on your notification bar and check that the mobile data toggle is switched on. Or go into “Settings,” tap “Connections,” and “Data Usage” and make sure that mobile data is switched on.
Step 3: On your smartphone, connect to the other phone’s hotspot.
On an iPhone, tap “Settings,” then “Wi-Fi,” and flip the switch on. Select the other phone’s Wi-Fi network from the list that appears.
On an Android smartphone, tap “Settings,” then “Connections”, then “Wi-Fi” and flip the switch on. Select the other phone’s Wi-Fi network from the list that appears.
Step 4: Combine the coverage from the 2 smartphones on your phone with Speedify.
- Download Speedify from the App Store or Play Store.
- Open Speedify and sign in, or create a free account, which includes 5 GB per month. Speedify automatically detects your 2 active connections: Wi-Fi (the other phone’s hotspot) and your own 4G/5G cellular, and uses both at once.
- Select the server you want to connect to. The “fastest” option usually works best.
You can now go back to what you were doing, with internet that keeps up. The data you use over the second phone’s hotspot counts against that phone’s plan, so take turns if your friend needs the fast connection too.
If both phones run Speedify, Speedify’s cellular sharing feature can pair them instead, so each phone can share its 4G/5G cellular connection with the other. Both phones need to be on the same local network: where there is no Wi-Fi, turn on Personal Hotspot on one phone only and connect the other phone to it.
Get Online Privacy when You Combine Coverage from 2 Smartphones with Speedify
Speedify works like a VPN and uses its own technology to combine multiple Internet connections together simultaneously. Because Speedify encrypts all the traffic from your smartphone to the Internet, you can:
- stay safe from hackers and snooping ISPs, especially when connecting to public Wi-Fi networks
- bypass content restrictions on hotel, school and work networks that block sites and apps, and unblock video streaming services you already use at home.
- avoid ISP data throttling for certain services like Twitch and YouTube.
Combine the 4G/5G cellular connections of 2 smartphones with Speedify, and you get a stable connection, faster internet and encrypted traffic at once.
