The Huawei AI Cube B900 (Three’s 4G Hub with Alexa) offers unlimited 4G home broadband with a built-in Amazon Alexa smart speaker.

In the UK, Three is offering the Huawei AI Cube B900 router with unlimited data for £23/month (also known as the 4G Hub with Alexa). Customers purchasing the device will also receive a free Amazon Echo Dot with their purchase.

Working as a two-in-one device, the AICubeB900 has an integrated Amazon Alexa smart speaker as well as giving you unlimited 4G home broadband on up to 64 devices at one time. This is all delivered without the need for a phone line or cable, making it a good alternative to fixed home broadband.

In this article, we’ll review the Huawei AI Cube B900 router from Three, including the price plans available and the capabilities of the device. We’ll also compare it to the Huawei HomeFi Plus B535 router from Three which is available at a lower cost of just £20/month.

Huawei AI Cube Price Plans

For many people, 4G technology now provides a viable alternative to fixed home broadband that’s delivered through a phone line or cable. As it uses mobile network technology, you can get a high-speed broadband connection without being limited by the speeds you can get through a phone line or cable. You can also get your broadband connection set up quickly without an engineer visit, and there’s the flexibility to bring your broadband connection with you to other places.

Three currently offers a choice of two 4G-powered home broadband routers: the Huawei B535 HomeFi+ (available from £20/month) and the Huawei AICubeB900 (available from £23/month).

As the more expensive of the two devices, the Huawei AI Cube B900 gives you a built-in Amazon Alexa smart speaker. This means you can use it to control your smart home devices, for listening to music or for making internet-based phone calls. This is in addition to the router capabilities, with support for Category 6 LTE download speeds (up to 300Mbit/s) and dual-band Wi-Fi (802.11ac).

At present, the Huawei AICubeB900 is available on a choice of three different plans. The best value deal is the 24-month plan giving you unlimited data for £23/month. There’s no upfront cost when taking the AI Cube on a 24-month contract. Alternatively, for greater flexibility, Three offers a 12-month plan costing £28/month plus £49 upfront, or a 1-month plan costing £32/month plus £149 upfront.

You’ll also receive a free Amazon Echo Dot with your Huawei AI Cube B900 hub. This will wirelessly connect to your AI Cube B900 router and will give you Alexa smart speaker capabilities in another room of your home.

If you replace your fixed-line home broadband connection with an AI Cube router, it may be possible to cancel your landline connection. This can save you in the region of £20/month, offsetting much of the cost of getting an AI Cube router. However, you’ll need to find an alternative way to make phone calls if you do this (e.g. using your mobile phone instead of a landline, or making internet-based phone calls using your AI Cube).

As an alternative to buying your AI Cube from Three, you can also buy the Huawei AI Cube from Amazon for around £99. You can then buy a SIM card separately for your AI Cube if you decide to do this (e.g. Three offers an unlimited data SIM card from £16 per month).

Huawei AI Cube B900

The Huawei AI Cube B900 is Three’s 4G home broadband router with a built-in Amazon Alexa smart speaker (4G Hub with Alexa). The router supports Category 6 LTE speeds (up to 300Mbit/s download and up to 50Mbit/s upload). Most users, however, will get more realistic download speeds of around 10-20Mbit/s depending on their location. The AI Cube’s home broadband service can be used on up to 64 devices at one time with dual-band 802.11ac wi-fi connectivity. There’s also an Ethernet socket for connecting a wired device to your network.

In addition to working as a 4G router, the AI Cube also doubles up as a smart speaker solution. It has four built-in microphones with far-field voice recognition and a 360° speaker. This means you can use it in much the same way as you would an Amazon Echo. For instance, you can control your smart home devices, make internet-based phone calls or listen to music through online steaming services. The AI Cube’s interface allows you to control everything by voice, simply by asking Alexa to do something for you.

Compared to the Huawei B535 HomeFi Plus router, you get fairly similar router specifications. Both routers support a maximum download speed of 300Mbit/s and have dual-band Wi-Fi connectivity on up to 64 devices at one time (including 802.11ac wi-fi). You do, however, lose some connectivity options. For instance, there’s no external antenna support. The AI Cube also has just a single Ethernet socket for connecting wired devices to your network, whereas the Huawei B535 has 4 Gigabit Ethernet sockets. The AI Cube also offers slower uploads (up to 50Mbit/s rather than 100Mbit/s).

The AI Cube can be used to control your home and to listen to music, in addition to being a router.

Being a 2-in-1 device with an integrated Amazon Alexa speaker, there are some trade-offs to be made in the AI Cube’s design. Most importantly, the optimal location to place a smart speaker in your home is normally fairly centrally in your living room. This may differ from the optimal location for a 4G router which is often closer to a window sill (to maximise the signal strength of your 4G connection).

For customers living in an urban area with fairly good mobile coverage, the trade-offs getting an AI Cube might be fairly small (as you possibly didn’t want to use an external antenna anyway and coverage might be better in the middle of your living room). However, for customers living in a suburban or rural area, a more mainstream router like the Huawei B535 will be a much safer bet.

You can see the full specifications for the Huawei AICubeB900 on Three’s website.

As an alternative to the AI Cube, you can combine the Huawei B535 router with something like a standalone Amazon Echo speaker. This is available for about £90. The advantage of having a standalone Amazon Echo speaker is that it can be placed anywhere in your home: it isn’t necessary to balance this against where you’ll get the best 4G network coverage.

Alternatives

The closest alternative to getting a Huawei AI Cube B900 router is getting the Huawei B535 HomeFi Plus instead.

The following table shows a list of price plans available with the Huawei B535 HomeFi Plus:

ServiceData AllowanceContract LengthUpfront PriceMonthly Price

Three 4G Hub
Unlimited Data24 month contract£0£17/month

Three 4G Hub
Unlimited Data12 month contract£19£20/month

Three 4G Hub
Unlimited Data1 month contract£49£30/month

For most people, we’d now recommend choosing the Huawei B535 over the Huawei AI Cube B900. You’ll save £3/month on your contract as the B535 is available for just £20/month. This gives a total saving of £72 over the length of your contract which is about enough to pick up a standalone Amazon Echo speaker.

For more information, please read our full review of the Huawei B535. Previously, Three also offered the Huawei B311 HomeFi router but this was withdrawn from sale in September 2019.

Other Mobile Networks

If you’re also looking at 4G-powered home broadband solutions from other mobile networks, you can consider Vodafone’s GigaCube and EE’s 4GEE Home Router.

Vodafone’s 4G-based GigaCube service starts from £30/month and includes a Huawei B528 4G router. This has a cylindrical design, just like the Huawei AI Cube B900, but it doesn’t have the built-in smart speaker capabilities. On the entry-level £30/month plan, you’ll only get 100GB of data included. This increases to 200GB for £40/month and unlimited data for £50/month.

  • I want to add ethernet switch and feed other devices to the AI cube, is this possible? In other words use the mobile broadband signal to feed hardwired devices

    • Hi Allan,
      Thanks for your comment. Yes, it should be possible to connect an Ethernet switch to the AI Cube using an Ethernet cable. This will mean it functions as just a 4G router and smart speaker, with your switch distributing the connection onto other devices.

    Hi there,

    I just ordered the Huawei AICubeB900 from three. I intend to use it with an amazon fire stick that is Alexa enabled.

    My question is: will the two Alexa’s get confused?

    Better yet: can I disable Alexa on the cube as I have no interest in streaming music, asking about the weather, or getting my horoscope. I just ordered the thing for basic WiFi to feed the fire stick.

    • Hi Jennifer,
      Thanks for your comment. To answer your questions:
      1. I believe the Alexa device in closest proximity to you should be the one that responds to your voice command. However, I haven’t actually tried this so I don’t know how well the feature actually works!
      2. You can mute the AI Cube’s microphone which will essentially disable the Alexa smart speaker functionality.
      Hope this helps,
      Ken

  • Hi Ken,
    Can you use the AI cube without a SIM card and as a stand alone Alexa enabled speaker? Our 3 contract has ended and we now have BT broadband

    • Hi there,
      Thanks for your comment. Yes, I believe it should be possible to attach your AI Cube to your BT Smart Hub using an Ethernet cable. This would allow you to use it as a standalone Amazon Alexa device.
      Ken
