What are the differences between Three's broadband devices?
The selection of mobile broadband devices that can be had with unlimited data include the Huawei 4G+ Mobile WiFi ,which is a portable, battery-powered device that supports speeds up to 300Mbps and enables you to share internet with up 16 devices at the same time. The Huawei E5573bs-322 4G Mobile Wi-Fi, is essentially the same but only supports speeds up to 150Mpbs and 10 devices at once.
There’s also Huawei B535, which is a 4G home broadband router that enables you to share internet with up to 64 devices simultaneously and supports speeds up to 300Mbps. As this is meant for the home it’s mains powered, but can be taken anywhere with mains power.
Then there’s the Huawei AI Cube, which is also a 4G home broadband router. So it’s mains powered, but it also lets you share internet with up to 64 devices. Plus it supports Cat 6 LTE, making it potentially faster than these other devices (with download speeds theoretically able to reach 300Mbps). Not only that, it also has a built-in Alexa speaker, so you can use it to control smart home devices, play music, and more.
Huawei HomeFi router used to be available, but this has now been discontinued and replaced the new and improved Huawei B535.

Do you really need unlimited mobile broadband?
It’s always worth checking how much data you actually need, since there’s a good chance you might not need unlimited data.
In fact, if you’re not planning to use mobile broadband much or will mostly just be using it for web browsing and social media (as opposed to video, big downloads, music and online gaming) then you shouldn’t need a vast data allowance. Calculating your data use can be tricky, but if you already have a mobile broadband device then your network likely keeps a log of how much data you use with it each month if you view your account.
For a more in-depth overview of how much data you might need, check out our guide – though note that actual amounts will depend on the type and number of devices you’re connecting to your mobile broadband.
Even if you plan to stream a lot of music or video, Three's zero-rated Go Binge could have you covered , as long as you use supported services.
Go Binge comes with mobile broadband plans with more than 15GB per month and lets you use Netflix, Apple Music, Deezer, Snapchat, SoundCloud and TVPlayer without using up any data, so you can effectively get unlimited mobile broadband data for those services.
With those services covered, your remaining data is likely to go far enough for every other need too, especially as you need to choose a data SIM plan with at least 15GB of monthly data to get Go Binge.
