Three is offering the Huawei B535 router with unlimited data on 4G home broadband from £20/month.

In the UK, Three is offering a 4G home broadband service with the Huawei B535 router (also known as the Huawei HomeFi Plus). The service starts from £20/month for unlimited data and allows you to connect up to 64 devices to the internet. Download speeds of up to 300Mbit/s are available through the router.

A major benefit of the new 4G home broadband service is it doesn’t require you to have a landline or cable connection. You’ll also get free next working day delivery of your router, with a simple plug-and-play setup and no need for an engineer visit.

In this article, we’ll review the Huawei B535 4G router and the HomeFi Plus broadband service on which it is offered. We’ll look at the price plans and router specifications before comparing it to rival 4G home broadband services. Finally, we’ll look at the coverage that’s available on Three when you’re using the Huawei B535 for your home broadband service.

Huawei B535 Price Plans

The Huawei B535 (HomeFi Plus) is Three’s latest 4G home broadband router. Replacing the old HomeFi B311 router, the newer Huawei B535 router is currently available from £20/month with unlimited data at 4G speeds.

The lowest-price deal currently available is when you take unlimited data on a 24-month contract. Normally, this will cost you £22/month, but you can get a special discounted price of £20/month when you buy through this link. Shorter 12-month and 1-month deals are also available if you’re happy to pay a little bit more and would like the extra flexibility:

Unfortunately, it isn’t currently possible to get the Huawei B535 router on a Pay As You Go basis.

If you decide to replace your fixed-line home broadband connection, it might be possible to cancel your landline if you don’t need it for other reasons (e.g. for making phone calls). This could save you in the region of £20/month on line rental, potentially making the Huawei B535 close to a cost-neutral solution.

Exclusive Offers

As a special time-limited offer, Three is offering a £2/month discount on the Huawei B535 with unlimited data. This means you can currently get it for just £20 rather than £22 per month on a 24-month contract.

To benefit from the £2/month discount, you’ll need to purchase the Huawei B535 through this special link. It isn’t necessary to use any voucher codes during checkout but you’ll need to make sure you complete the entire purchase online.

Huawei B535 Router

You’ll be supplied with a Huawei B535 router when you sign up for Three’s HomeFi Plus service (sometimes also referred to as a WebBox). The Huawei B535 router will connect to Three’s 3G and 4G network, producing a wi-fi network that up to 64 devices are able to connect to at the same time. This includes all of the devices you have at home including your laptop, tablet, smartphone, smart TV and other smart home devices.

The Huawei B535 router supports up to Category 7 LTE download speeds (up to 300Mbit/s download and up to 100Mbit/s upload). However, Three says average download speeds could be closer to 14Mbit/s, depending on the level of coverage available where you live.

The Huawei B535 has dual-band Wi-Fi connectivity, including 802.11ac wi-fi at 5GHz. This allows you to have up to 64 devices connected wirelessly to your router at one time. In addition, there are also four Gigabit Ethernet sockets allowing you to connect wired devices to your home network.

When it arrives, setting up the Huawei B535 is a simple plug-and-play affair. You’ll need to insert the provided SIM card into your router and you can then plug in the router at the mains. Your 4G home broadband service should then be ready-to-use in less than one minute. As there are no engineer visits or line installations, this makes it incredibly easy and convenient to set up. You can also move the router to other places with ease (e.g. bringing it with you on weekends away from home or taking it when moving to a different address).

If you’d like to attach an external antenna to your router, the Huawei B535 has two sockets for a SMA antenna. This can be used to improve the coverage and speeds you get on your router, especially if you’re living in a rural area where the coverage is a bit weaker.

You can see the full specifications for the Huawei B535 on Three’s website.

Huawei B535 vs AI Cube B900 vs HomeFi B311: Side-By-Side Comparison

The Huawei B535 HomeFi Plus is Three’s latest 4G home broadband router. Alongside it, Three also offers the Huawei AI Cube B900 which is a two-in-one device, combining a 4G home broadband router with an Amazon Alexa smart speaker. The Huawei B535 replaces the older HomeFi B311 router.

The following table shows a side-by-side comparison of the three different routers:

Review:Three HomeFi Plus ReviewThree AI Cube ReviewThree HomeFi Review

In our opinion, the Huawei B535 should be your go-to choice when you’re looking for a 4G home broadband router on Three. You’ll get modern specifications like Category 7 LTE download speeds along with 802.11ac dual-band wi-fi. Both of these features will allow you to maximise your home broadband performance. The inclusion of 4 Gigabit Ethernet sockets for connecting wired devices is also very welcome, along with the 2 SMA sockets for attaching an external antenna.

The Huawei B535 has 4 Gigabit Ethernet sockets and 2 SMA connectors for attaching an external antenna.

With the AI Cube B900, you’ll additionally get a built-in Amazon Alexa smart speaker. There are, however, some sacrifices to be made elsewhere in terms of network connectivity features. For instance, the AI Cube router only has one Gigabit Ethernet socket for connecting wired devices to your network. There’s also no way to attach an external antenna.

Typically, in order to maximise the signal strength of your 4G connection, it’s recommend you place your router close to a window, ideally in an upstairs room facing towards your nearest mobile mast. This doesn’t always align well with where you’d like to use a smart speaker (normally best placed fairly centrally in your living room). For this reason, it’s usually a more practical solution to get a Huawei B535 router, saving you £5/month compared to the AI Cube. You can use this in conjunction with a standalone Amazon Echo speaker which is available for about £90. A standalone Amazon Echo device can connect to your Huawei B535 router using wi-fi.

Three’s older Huawei HomeFi B311 router was withdrawn from sale in September 2019. It has now been replaced by the Huawei B535 HomeFi Plus which offers faster download speeds and a more powerful wi-fi connection.

On Three, you’ll receive the B535-232 version of the Huawei B535 router. This is sometimes also referred to as the Huawei 4G Router 3 Pro.


The AI Cube has a built-in Amazon Alexa smart speaker.

The closest alternative to the Huawei B535 is Three’s AI Cube router. Starting from £25/month with unlimited data, the AI Cube is a two-in-one device that gives you a built-in Amazon Alexa smart speaker.

We'd love to hear your thoughts and any questions you may have. So far, we've received 97 comments from readers. You can add your own comment here.

  • This may be a silly question as I don’t really know much about the technology: will the Huawei B535 connect with another WiFi network instead/as well as 4G via the sim? I live in a marina which offers free WiFi (but I will need to boost the signal to access it inside my boat). When cruising I need to use mobile broadband. Will the B535 do both? Or do I need another piece of kit as well? Any advice much appreciated.

    • Hi Rod,
      Thanks for your comment. Sorry – I didn’t quite understand your question: are you trying to use the Huawei B535 as a wi-fi repeater/extender? If so, I don’t believe it’s possible for it to do this. However, I would have a look at your laptop or mobile phone as it’s possible this already includes the functionality. Alternatively, you could buy a separate wi-fi repeater device.

  • Please DO NOT go with Three! Their network has been in a state of collapse since at least April 2019. I joined them in May, having dumped ADSL and gone 4G for home internet. It started out OK, with decent speeds. However, over the course of last year my speed deteriorated to the point where it was unusable even for browsing (I got 0.01mb on one speed test!).

    Luckily, I managed to break my contract at the half-way point over live chat when Three finally agreed that my experience of their network wasn’t as good as it should be and let me go without further penalty.

    I’ve now switched to VOXI and the difference is night and day with speed. At least 30mbps throughout the day, even though the masts are not far from each other. O2 and EE were even faster when I tested their SIMS in my Huawei router, VOXI are the only ones that offer a 30 day contract for unlimited data.

    It’s not just me either – see Three_Is_Broken on Twitter. In short – DO NOT sign up to Three! It’s cheap for a reason.

    • You’re not kidding… Last summer I moved from Vodafone to Smarty (which uses the Three network). Yes it was cheaper and my allowance went from 50GB to unlimited, but for the majority of the day the connection would time out for 10+ seconds at a time. I left them last September – sounds like things haven’t improved since then.

  • A little bit of feedback for anyone considering this offer from Three. Online ordering process was simple, although it was a bit strange that Three requested direct debit AND credit card details. I haven’t seen any charge to the credit card, so I assume this was either some form of credit check or a pre-authorisation charge. I signed up using the referral link above for the £20/month deal, however, my first bill said £29/month. After a phone call, email and chat with Three I think this has finally been resolved, so pay attention to your first bill and double check your monthly charge.

    Service wise I’m typically seeing about 30Mbps down, 5 Mbps up. Fastest was 41/13. However, this is *highly* dependent on the mast you connect to. These speeds were achieved with 2/3 bars on 1800MHz (band 3). I have to position the B535 router in an upstairs bedroom window to keep this connection. Moving it anywhere else in the house and it will fall back to 5 bars on 800MHz (band 20). On band 20 the best speeds are about 15/10, but usually more like 13/7. It’s interesting that the B535 will connect to band 3, even when there is a significantly stronger band 20 signal, so it’s clearly testing for speed, not just signal strength. For me at least, band 3 gives the best download speeds, whereas band 20 consistently performs better in uploads.

    Unfortunately external antennas aren’t helping too much. I bought the Poynting XPOL-1, and no matter where it is positioned or facing the B535 will only ever connect to band 20. This leads me to one of the downsides of the B535 – there is no way to specify which band to connect to. I will either need to locate the antenna much higher in the house than I’m willing to go on a ladder, or investigate different 4g modems (B525 seems to allow band locking?). If Three/Huawei could release a firmware update to give more control on the modem that’d be even better.

    With all that said, the speed is a huge improvement on the 14/1 BT “fibre” service I’ve tolerated, and since I was mostly interested in improved upload speeds, even if the B535 only connects to band 20 it’s not a complete disaster. Definitely worth a try, but don’t expect an external antenna to fix a poor connection, you might just end up connecting to a different mast.
