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

In the UK, Three is offering a 4G home broadband service with unlimited data on the Huawei B535 WebBox from £20/month. The service allows you to connect up to 64 devices to the internet, with download speeds of up to 300Mbit/s available on 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 can also get free next-day delivery of your router, and there’s a simple plug-and-play setup when the router arrives (with no need for an engineer visit).

In this article, we’ll review the WebBox service from Three and the Huawei B535 router that’s supplied. We’ll compare it to rival 4G home broadband services, including those that are available from Three and rival mobile networks like Vodafone and EE. Finally, we’ll look at the coverage that’s available on the WebBox service.

WebBox Price Plans

The Huawei B535 WebBox is Three’s new 4G-based home broadband service. Available as an alternative to the HomeFi B311 router and the Huawei AI Cube B900 router, the WebBox service starts from £20/month for 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 £23/month, but you can get a discounted price of £20/month when you buy through this link. Shorter 12-month and 1-month contracts are also available if you’re happy to pay a little bit more upfront and would like the added flexibility:

Unlimited Data24 month contract£0£20/month
with special offer
Unlimited Data12 month contract£29£28/month
Unlimited Data1 month contract£79£32/month

Unfortunately, it isn’t currently possible to use the WebBox on a Pay As You Go basis.

If you decide to replace your fixed-line broadband connection, it might be possible for you to cancel your landline if you don’t need it for phone calls. This would save you in the region of £20/month for line rental, potentially making the B535 WebBox close to a cost-neutral solution.

Exclusive Offers

As a special time-limited offer, Three is offering a £3/month discount on the Huawei B535 with unlimited data. This means you can currently get it for just £20 rather than £23 per month on a 24-month contract.

To get the £3/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 WebBox Router

Three’s WebBox service comes with a Huawei B535 router included. The 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 one 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 will be closer to 14Mbit/s on the service (depending on the 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 any one time. In addition, there are also four Gigabit Ethernet sockets allowing you to connect wired devices to your home network.

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.

Review:Three HomeFi ReviewThree WebBox ReviewThree AI Cube Review

In our opinion, the Huawei B535 WebBox should now be your go-to choice when you’re looking for a 4G 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 connecting an external antenna.

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

With the AI Cube, which is slightly more expensive at £25/month, you’ll additionally get a 360° Amazon Alexa smart speaker built-in. There are some sacrifices to be made elsewhere, however, in terms of network connectivity.

For instance, the AI Cube router only has a single Gigabit Ethernet socket for connecting wired devices. There’s also no way to attach an external antenna. Typically, in order to maximise the signal strength of your 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 placed fairly centrally in your living room). For this reason, it may work out to be a more practical solution getting a Huawei B535 WebBox and using it in conjunction with a standalone Amazon Echo speaker (available for around £60).

Alternatives

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

The closest alternatives to the Huawei B535 WebBox are Three’s HomeFi router and AI Cube router.

If you’re looking for a lower cost alternative to the Huawei B535, Three’s HomeFi router is available for just £21/month. You’ll get a more basic router with up to Category 4 LTE speeds and single-band 2.4GHz Wi-Fi:

  • Hi Ken

    Great article – thanks very much for the review, it’s really helping with my decision to go for 4G home broadband in my new place. I’m coming up with almost price parity on going with a 12 month contract with a B535 with three and buying a B525 from Amazon and just getting a sim-only contract. Is the 535 much better for day-to-day use to warrant getting it over an unlocked 525? Thanks again!

    • Hi Lewis,
      Thanks for your comment. I don’t think there are really that many differences of note between the Huawei B525 and the Huawei B535. The latter supports Category 7 LTE as opposed to Category 6 LTE, so in theory you could get faster uploads on the B535. The B535 is also sold as a home broadband package (whereas with the B525 you’ll be building your own solution so you won’t necessarily have the same level of support from Three).
      On the other hand, buying an unlocked B525 and getting a unlimited data SIM card will give you an allowance of minutes which you can use through a RJ11 phone. For some people, that makes it a more suitable solution if you’re looking to replace your landline connection.
      Ken

      • Thanks, Ken – much appreciated! I’ve gone for the B525 as it was £100 and I hadn’t considered using it as a landline. Thanks again 🙂

  • Hi, stumbled across your site while researching my Huawei B525..

    I am with Three on their unlimited 4g plan, I bought my own modem,as above, they sent me a sim.. I was getting 52mb down and 47mb up until today, it seemed like it was capped so after spending over an hour on the phone to them, most of it waiting, it turns out they sent me the WRONG sim, apparently Three have different sims for DATA ONLY.

    They have agreed to cancel my 24 month contract without charge as it was their fault, I have now just signed up to Threes 24 month contract with their Huawei B535 modem for £18 a month.

    Looks like Ill have a spare kodem for sale soon 🙂

    Loved reading through here and about to read your Antenna Guide.

  • Murray Elliot said:

    I got the 535 today (after returning the 311 THREE sent me by default as couldn’t find the WebBox on their website). Attached a Poynting antenna sitting on the windowsill. With the 535, and the antenna, I’m measuring 20-27Mb/s download pretty consistently (3Mb/s upload)

    For context, we live in the country in a stone cottage with thick walls and small windows. At best I was getting 7Mb/s on my phone and 3Mb/s on our Sky copper wired “broadband”!

    Happy bunny

    • Hi Murray,
      Which Poynting antenna did you purchase? I’ve just ordered the 535 from Three and I also live in a remote area. I currently get just over 1mbps download in the evening. If I lean out of an east facing bedroom window and look north with binoculars I can see a mast of top of the church. I’m
      Expecting much better speeds with the 535 😉

      • Murray Elliot replied:

        Hi Jon.
        I bought a simple, cheap Poynting Omni indoor/outdoor SiSo 3G/4G antenna from Amazon https://www.amazon.co.uk/gp/product/B07DVNJ941/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1
        My thinking was that if I was able to get 2-3 bars with my phone outdoors, I probably wouldn’t need too much gain.

        Most of the time the router shows 5 bars, dropping to 4 bars occasionally. It sits on my windowsill. If your conditions are less favourable, then perhaps the 4G-XPOL-A0001 Cross Polarised 4G Omni LT Antenna would be more appropriate, or if directional gain is required, then the 4G-XPOL-A0002 would give you more gain.

        • Hi Murray,
          Thank you for the information.
          I am very happy and actually quite staggered by the speeds I’m getting. I’ve tried the router in various different places around the house and settled on a middle window sill upstairs. The front of the router is pointing in the direction of the mast.
          This morning I got 52.7 download and 21.2 upload! That’s with no external aerial!
          I just have one bad spot in the house and unfortunately that’s in my office so I’ll have to get a booster… or just move the router when I’m working in there 😉
          So far I am very, very impressed 🙂

  • Hi Ken, just checking how they can claim 300mbps but average 14 mbps? I understand 300 is theoretical laboratory conditions but that’s a huge difference. 3 claim excellent coverage in my area. Thanks.

    • Hi Mark,
      Thanks for your comment. The Huawei B535 hardware supports Category 7 LTE technology which caps out at a maximum of 300Mbit/s. In reality, however, actual speeds vary wildly depending on lots of network-related factors like location, congestion, interference, number of other users, etc.
      The average download speed figure is defined by the Advertising Standards Authority as something that at least 50% of customers are able to get during the evening peak hour (8pm-10pm). Obviously, this is tricky for a 4G broadband provider as someone could decide to use the service wherever they like, including in an area with poor coverage or with a badly placed router. Therefore, make of it what you will (some people will get much better speeds in an area with good coverage (especially with an antenna), others will get worse speeds in an area with poor coverage or with a badly placed router).
      EE is slightly more aggressive in their marketing for 4GEE Home – they claim to offer average download speeds of 31Mbit/s on a router that similarly caps out at 300Mbit/s.
      Ken

  • Hi I’m receiving my B535 today but I was wondering how would I set up a password to block others from connecting onto my wi-fi
    Many thanks

    • Hi Housni,
      Thanks for your comment. I believe the Huawei B535 should be pre-configured with a password to protect your Wi-Fi network. If, for some reason, you’d like to change the password, this should be possible following the information in the manual.
      Ken

  • Anyone know the username for logging into the B535 192.169.1.8 homepage ?
    Running software that needs this

    Or also where a manual is available ?

  • Thank you for this; it is very informative. Does the b535 have the option for internal antenna?

    Thank you in advance.

    • Hi Rhodri,
      Thanks for your comment. Yes, the Huawei B535 has a built-in antenna so it’s possible to use without buying an external antenna. Alternatively, if you’re asking whether it’s possible to buy an indoor antenna (as opposed to an antenna that you put outdoors), then yes, this should also be possible. The Huawei B535 accepts 2x SMA antennas – see my guide to 4G antennas for more information.
      Hope this helps,
      Ken

  • David Astley said:

    Ken, I have two grandsons who have a PS4 & Xbox One for gaming. I am in a good Three 4G area, would the WebBox be OK for online gaming?

    • Hi David,
      Thanks for your comment. It should be fine to connect a PS4 & Xbox One to the Huawei B535 WebBox for online gaming 🙂 One thing to be aware of, however, is that 4G broadband has higher latency or ‘ping’ compared to traditional fixed-line broadband. We’re talking a delay of around 0.05 seconds (50ms) rather than 0.01-0.02 seconds (10-20ms). This is fine for most online games, except from those that might require super-fast responsive times (e.g. shooters).
      Hope this helps,
      Ken

  • Excellent website Ken..Been a long time subscriber, & I’m a Three 3 Customer..Very interesdted in swapping awful old deal with TalkTalk for this..But can I connect my landline phone ? Or can I connect Mobiles ?

    • Hi Verdi,
      Thanks for your kind feedback on the website, so lovely to hear from you! You can connect your smartphone to the internet via the Huawei B535 WebBox (as can you connect other devices like a tablet, laptop, TV, etc). You can also make voice-over-IP calls on any of these devices (e.g. using Skype, WhatsApp, etc). What you can’t do is to plug a phone in directly to the B535 router to make and receive phone calls over the SIM card. If you’d like to do this, you can buy something like an unlocked Huawei B525 (approx £120 from Amazon). This has a RJ11 socket so you can connect a phone to the router, in order to make and receive phone calls using the SIM card in your router. You can use it with an unlimited data SIM card.
