Three HomeFi Plus and AI Cube 4G home broadband: what you need to know

Don’t want to pay for a landline or installation? Prefer a home broadband solution that’s portable too? Maybe you’re looking for a back-up connection while you’re working from home during the Coronavirus pandemic? Three’s HomeFi Plus and AI Cube could be what you’re looking for.

Back in the dim and distant past, mobile internet was good enough only for light browsing and watching the odd video while you’re on the move. Much has changed since then.

With the advent of blazingly quick, more reliable 4G, mobile broadband speeds are now easily a match for fast fibre fixed line broadband from the likes of BT, Sky and TalkTalk.

The upshot is that 4G home routers, such as Three’s HomeFi Plus and AI Cube, are now a very viable alternative to fixed line home broadband. Better still, they’re convenient, portable and affordable too.

Read on and we’ll take a look at what they’ve got to offer.

HomeFi Plus and AI Cube: what’s the difference?

Three homewifi

HomeFi Plus lets you connect up to 64 gadgets, such as laptops, smartphones and consoles and whatever other internet-enabled kit you’ve got around the home.

As you can see above, it looks like any other router.

But unlike those routers, you can set it up anywhere. And you easily can move it around the home if there’s an area where your signal is weak.

Huawei AI Cube

The AI Cube is a different kettle of fish. Like the HomeFi Plus, it allows you to connect 64 gadgets simultaneously.

However, as you can see it looks much more like a smart speaker than a router. That’s because as well as being a wireless router, Amazon’s Alexa voice assistant is embedded within.

That means the AI Cube allows you to control your smart home with voice commands, as well as conduct voice web searches and listen to music on Apple Music, Spotify and more.

Price and contracts

You can get the HomeFi Plus is available on a choice of 12-month or 24 month or a one-month rolling contract, while the AI Cube is solely on offer on 12-month and 24-month contract terms.

All plans come with unlimited data. So even if you live in a busy household, student home or large family home, you won’t have to worry about incurring extra charges for exceeding a usage limit.

Because the HomeFi Plus is up for grabs on a rolling contract with a minimal upfront fee, it’s a really good bet if you’re in the market for an emergency, back-up connection in the event that your fixed line broadband goes down or slows dramatically.

That’s not out of the question right now, as unprecedented numbers of home workers are putting a lot of strain on broadband networks.

If you live in a rural location or in a brand new home that’s not been connected with a broadband network before, you’ll need to book an engineer to get traditional home broadband.

The same goes if you want to switch from the likes of BT, TalkTalk or Sky to Virgin Media.

The HomeFi Plus and AI Cube do away with all that fuss. As plug-and-play devices, all you’ll need to do is plug in and insert the 4G SIM that came with it. And you’re up and running with your broadband service straight away.

Of course, being able to self-install HomeFi Plus and AI Cube and not have to admit an engineer to your home is a particular boon at the moment, given that we’re all practising social distancing.

It’s also worth noting that Three pledges next-day delivery. Which makes HomeFi Plus and AI Cube well worth a look if you need a broadband service in a hurry.

No landline charges

No one likes paying for a landline they don’t use. But because most broadband is delivered using the telephone network, lots of us are forced to.

Neither HomeFi Plus or AI Cube require to take a landline. Which means you can look forward to an instant saving.

For instance, sign up for 24-month 4G contract the HomeFi Plus with unlimited data and you’ll pay just £22 per month.

That’ll get you speeds that are likely to be in line with BT’s Fibre 1 or Sky Superfast, which at the time writing are priced £27.99 per month and £27 per month respectively.


Three’s 4G service covers 99.8% of the UK population. So you’re almost certain to be able to sign up for the HomeFi Plus or AI Cube on a 4G plan.
