Whether you want to bring internet with you on the move with a battery-powered mobile broadband device or upgrade your home internet to speedy 4G or 5G home broadband, Three has devices to suit, along with unlimited data plans, so you never need to worry about how much data you’re using.
On this page you’ll find both kinds of mobile broadband, and we’ve detailed the specific devices that Three sells below. But in brief, a battery-powered 4G or 5G router is something you can slip into a bag and take with you wherever you go, allowing you to beam out a Wi-Fi network to all your portable gadgets, like laptops and tablets.
This is ideal if you often find yourself out and about without access to Wi-Fi (or only with access to slow, unsecure, or expensive public Wi-Fi). However, battery-powered routers don’t always support a huge number of simultaneous connections, and of course you need to make sure the battery is charged.
The other kind of 4G and 5G broadband that Three offers is 4G and 5G home broadband. With this, you plug the router into a socket in your home (or anywhere else where you have access to sockets) and it will provide a permanent 4G or 5G-powered Wi-Fi connection to all your devices, much like fibre broadband does.
These home broadband routers also typically support 64 simultaneous connections, so you should easily be able to get everything online. But they don’t have a battery, so they’re not particularly useful for taking with you places – they’re more designed to stay in one spot.
The Three 4G MiFi is a portable, battery-powered device that supports speeds of up to 300Mbps and enables you to share internet with up 32 devices at the same time. It also supports both 2.4GHz and 5GHz Wi-Fi simultaneously.
It’s very small and light, so it’s ideal for carrying with you, it has a range of around 10 metres, and its battery lasts for up to 8 hours of use, or 300 hours of standby time.
For home broadband, Three’s top option is the Three 5G Broadband, which is a 5G home broadband router, so it needs plugging in, but it supports extremely high speeds, theoretically reaching download speeds of up to 4.7Gbps (though Three’s network tops out at 1Gbps currently). Real world speeds are a lot lower, but still averaged 445Mbps in our Three 5G Broadband review.
The Three 5G Hub also supports 64 simultaneous device connections, 2.4GHz and 5GHz Wi-Fi, and has two Ethernet ports for wired connections along with extension ports for external antennas, in case you need a signal boost.
The Three 4G Home Broadband Hub is a mains-powered 4G home broadband router which supports download speeds of up to 600Mbps, allows for up to 64 simultaneous device connections, and includes Ethernet ports.
So it’s not as fast as the Three 5G Broadband, but if you only have a 4G signal at home then this is a top choice.

There are no speed or usage restrictions on Three's unlimited broadband plans in the UK, but they are designed for personal use only and roaming restrictions apply. You can only use 12GB in Go Roam destinations, and on most plans this comes at a small daily charge.
Three allows you to roam with its unlimited mobile broadband plans, so you can get all your devices connected to Wi-Fi even when outside the UK.
However, on most plans roaming comes with a small daily charge, and there’s also a fair usage limit of 12GB per month when roaming – so you can’t actually use unlimited data when outside the UK.
Yes, unlimited data only SIM plans for use in tablets and mobile broadband devices are available from Three on 1-month, 12-month, and 24-month contracts and at competitive prices. So just grab one of these and put it in the 4G or 5G broadband device you already have.
Yes, Three 5G Home Broadband and the Three 4G Plus MiFi are available on 1-month rolling contracts. You can also get a data-only SIM on a 1-month plan and put that into your existing mobile broadband device or tablet. However, no Pay As You Go plans are available for unlimited 4G and 5G broadband.
If you’re not happy with your coverage or speeds then check out our guide to improving your Three signal. You might also want to invest in an external antenna if you have Three home broadband, as this can help boost your signal.
Other things to try include using the Three 5G Broadband app to find the best location for your router and run diagnostics, or placing your home broadband router on a windowsill.
If all else fails, Three offers a 30-day money back guarantee with all 5G and 4G home broadband plans, as well as for mobile broadband.
