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

In the UK, Three is offering a 4G home broadband service with unlimited data on the Huawei B535 router (also known as the Huawei HomeFi Plus). The service starts from £20/month 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 key 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 next-day delivery of your router for free, with a simple plug-and-play setup when the router arrives (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 new 4G-based home broadband service. Replacing the old HomeFi B311 router, the new Huawei B535 router is 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 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 want the added flexibility:

Data AllowanceContract LengthUpfront PriceMonthly Price
Unlimited Data24 month contract£0£20/month

Unlimited Data12 month contract£29£27/month
Unlimited Data1 month contract£79£31/month

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 HomeFi Plus 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 known as 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 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 on the service (depending on the coverage that’s 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 any 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 easily move the router to other places (e.g. on weekends away from home or 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 some sacrifices to be made elsewhere, however, in terms of network connectivity features. For instance, the AI Cube router only has a single 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 and facing towards your nearest mobile mast. This doesn’t always align with where you’d like to use your 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. You can use this in conjunction with a standalone Amazon Echo speaker which is available for about £90 (the Amazon Echo can connect to your Huawei B535 router using wi-fi).

The old 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.

Alternatives

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.

  • I have a huawai b722 mifi on three with good signal but get a lot of buffering when live streaming will a b535 help with this issue.

    • Hi Robert,
      Thanks for your comment. It’s really difficult to say what difference you should expect using a Huawei B535 instead of a MiFi. The coverage will almost certainly be better due to the configuration of the device (it has a larger antenna, is a mains-powered device, etc) and I would hope this translates through to a better overall experience. You also have the ability to attach an external antenna to it if required. It’s possible, however, you might experience the same issue as on the MiFi if the buffering is caused by congestion on your local mast rather than coverage so you’ll really need to try it in order to find out.

  • Hi Ken
    Thank you for your very informative article. I am considering signing up with Three for the B535 on their 24-mth contract.
    Since Three’s packages also include Go Roam, I would like to take it on holiday to Costa Rica when I head there next month, great perk!
    However I read Three’s support page “Using our services abroad” on http://support.three.co.uk/SRVS/CGI-BIN/WEBISAPI.DLL?Command=New,Kb=Mobile,Ts=Mobile,T=Article,varset_cat=roaming,varset_subcat=4147,Case=obj(42690) and they say “Not all dongles and Mobile Broadband devices may work in all countries we’re afraid (such as the USA), because the networks in those countries operate on a different frequency from the UK”.
    Do you know if the B535 will in fact work in Costa Rica? (not very techy, so not sure what frequency does mobile networks in costa rica operate on)
    Kind regards

    • Hi Cristin,
      Thanks for your comment, and a very good question! A quick search online suggests they use 2100MHz for 3G in Costa Rica along with LTE bands 3 and 7 for 4G. These are the same bands we use in the UK, so the Huawei B535 should work without any issues 🙂
      Hope this helps,
      Ken

      • Hi Ken
        Thanks so much for the quick response, I really appreciate people like yourselves setting up blogs like these who are really useful for people like me 🙂
        I actually have one further thing I was wondering re using Three’s mobile broadband in a Go Roam destination (ie Costa Rica in this case). I know they apply a maximum data usage of 12GB even tho the contract is unlimited data (in the UK). However they offer the Data Passport and I can’t seem to find anywhere in their website nor the web if this can be purchased for a mobile broadband contract, or if it’s only for phone contracts. Would you have any idea?

        In fact is there any difference between the SIM that is inserted into the B535 vs a mobile phone?

        Many thanks again 🙂

        • Hi Cristin,
          No worries – I’m really pleased to see that it’s helpful!
          There’s more information here about the Data Passport offer. Like you say, it’s £5/day for unlimited data without any restrictions and is available to Pay Monthly customers. I believe it should be possible to get this on the SIM card included with the B535 (as it’s also Pay Monthly), though it might be worth double-checking directly with Three if this is an important aspect of whether you choose this device.
          There are a couple of differences between smartphone SIM cards and mobile broadband SIM cards (namely, inclusive minutes and texts only being available on smartphone SIMs).
          Ken

          • Hi Ken
            Actually I have a further question if you don’t mind 🙂
            If the mobile broadband router takes a SIM that’s like a phone SIM, then can I also buy an unlocked product (eg Huawei B525) and then put my existing phone SIM into it, and it should be able to work (ie get data and broadcast it using WiFi)? (Subject to my SIM’s data allowance of course)
            Thanks!

          • Hi Cristin,
            Not at all! You’re absolutely right – you can just use a normal smartphone SIM card in your router, subject to the normal data allowance on your SIM. The Huawei B525 is a great router for this. In fact, many people used to combine the Huawei B525 with a Three unlimited data SIM card, until they released the Huawei B535 which generally works out a little bit cheaper than a do-it-yourself solution (as the £20/month subscription includes a router when you get the Huawei B535).

    Hi, just got a b535 from eBay and an unlimited data sim from EE. Speed is good, it connects to our phones, iPads, etc, it won’t connect to our Sonos system, robotic vacuum, or our Samsung smart tv wired or wirelessly. And ideas?
    Thanks

    • Hi Joanne,
      Thanks for your comment. There shouldn’t be any technical reason why these devices can’t connect to the B535 router (it just produces a regular wi-fi network in the same way as any other router). Are you receiving a certain error message on these devices and does it still persist when you delete and set up the network again?
      Ken

      • Joanne Button replied:

        Managed to fix it ourselves. Was down to the network selection. It was on EE, we changed it to automatic and it worked!
        Thanks anyway.
