How can I combine coverage from 2 carriers using an Android phone mobile hotspot and Speedify?

Speedify is a fast bonding VPN that can combine multiple connections on your laptop or smartphone. But more importantly, Speedify detects when one of those connections is weak. Then, it seamlessly transfers your traffic to the other, stronger connection, so you never have to deal with dropped calls and interrupted video again. This technology is called Channel Bonding.

There's a couple ways to use 2 carriers on your Android phone at the same time with Speedify.

Method #1: Use your Cellular + a Wifi Hotspot

Step 1. You’ll need to set up a mobile hotspot on your friend’s Android phone. Navigate to the phone’s connection settings and tap “ Mobile Hotspot and Tethering” and tap on Mobile Hotspot to set it up. Set the hotspot name and password and flip the switch on.

Step 2. Open up Wi-Fi settings on your phone and connect to the other phone’s hotspot. Normally, your phone will only use one connection at a time, but with Speedify, you can combine bandwidths to use both connections at once!

If you don’t already have Speedify installed on your phone, download it from the Google Play Store. Turn on the app, and you should see both the cellular connection and the other phone’s mobile hotspot contained inside connection bubbles at the top of the dashboard. Turn on Speedify by tapping the switch. 
And presto! You’re combining two connections using the magic of Channel Bonding for increased speeds, better reliability, and air-tight security thanks to Speedify’s VPN protection.

Method #2: Use Pair & Share!

Pair & Share is a unique feature in Speedify that allows you to easily share Cellular connections back and forth between multiple Speedify users (devices) on the same local network, without the need for additional cables or adapters.

The feature works almost like a turbocharged personal hotspot, but instead of just one device sharing its connection with another, once paired, both devices can share and receive each other’s connections simultaneously. The more devices you pair with, the more connections you’ll have access to!

And of course, the traffic between devices is fully encrypted, and you always maintain full control over which devices can do what - and can set permissions, limits, or unpair from other devices at any time.

Step 1. Connect both your devices to the same local network.

Step 2. Pair your devices by heading into the Pair & Share menu.

Step 3. Under Unpaired Devices, choose the device you want to pair with, and you will be prompted to send a pairing request to that device.

Step 4. Accept the pairing request on the other device.

And presto (again)! Your phones can now share their Cellular connections between each other, and you can enjoy better speeds (your connection over Pair & Share can be up to 10 Mbps) and added stability on both devices!
