If you’re unable to get Three’s 4G home broadband service in your area, you can get the 4G Plus MiFi instead. This is a 4G mobile broadband hotspot with the additional benefit that you can use it as a battery-powered 4G hotspot.

4G Broadband Plans

For many people, 4G technology now delivers similar or even faster download speeds than traditional fixed-line home broadband.

On Three’s 4G home broadband, you can access ultrafast download speeds of up to 600Mbps. This does, however, vary substantially depending on where you live. Three says you should be able to expect an average download speed of 50-100Mbps on their new 4G Hub.

For customers wanting to replace their fixed-line home broadband connection, it’s currently possible to get unlimited 4G home broadband for just £14/month. There’s no upfront cost when you take this on a 24-month contract. Alternatively, a 12-month plan is also available, or a 24-month plan with an inclusive 32″ LG Smart TV.

When you take 4G broadband from Three, you’ll get a new 4G Hub included in the price. This is also known as the ZTE MF286D.

If you decide to replace your landline connection with Three’s 4G home broadband, it might be possible for you to stop paying a rental charge on your landline. This should save you in the region of £20 per month, potentially making it close to a cost-neutral solution.

Between September 2019 and June 2021, 4G home broadband customers were provided with a Huawei B535 HomeFi Plus router. Prior to that, customers received the Huawei B311 HomeFi instead.

5G Broadband Plans

For customers living in a 5G coverage area, it will also be possible to get Three’s 5G home broadband service. This can offer up to gigabit download speeds (1,000Mbps) but Three says an average speed of 100Mbps is much more realistic.

At present, you can get 5G broadband for just £21/month on a 24-month plan.

Three Broadband Speeds

On Three’s home broadband service, you can access download speeds of up to 600Mbps on 4G and download speeds of up to 1,000Mbps on 5G. However, both of these are maximum theoretical speeds and the actual real-world download speeds will normally be slower than this.

The following factors can affect the download speeds you’ll get on Three Broadband:

  • The 4G or 5G signal strength where you are. You’ll normally get faster download speeds if you’re located in an area with good 4G or 5G coverage.
  • The location of your hub. To get the best performance, it’s normally best to place your 4G Hub or 5G Hub close to an upstairs window. This should face in the direction of your nearest mast.
  • An external antenna can improve your speeds. Both the 4G Hub and the 5G Hub have a built-in antenna. If you’re living in an area with poor or marginal signal, adding an external antenna can significantly improve the speed and reliability of your connection.
  • The capacity on your local mast. Your download speeds will also be affected by the amount of capacity available on your local mast. For instance, if lots of other people are also using the service at the same time, this may reduce the speeds you get.

Because of the large variation in download speeds based on multiple different factors, Three normally takes a fairly conservative approach when it comes to marketing their download speeds.

They normally say you’ll get an average download speed of 50-100Mbps on 4G home broadband and an average download speed of 100Mbps on 5G home broadband. This is based on peak-hour download speeds (between 8pm and 10pm). It’s also measured across the country, including areas where coverage might be poorer. In practice, you might be able to get much faster download speeds than the average (or much slower download speeds if you’re in an area with poor coverage or congested masts).

If you use Three’s broadband availability checker, they’ll run an automated check on coverage and capacity for you. This means you’ll only be offered a 4G or 5G home broadband plan if they think the signal is strong enough and if there’s enough capacity available where you are.

Three Broadband Hubs

4G Hub

When you sign up to Three’s 4G home broadband service, you’ll receive a 4G Hub router.

The 4G Hub router works in much the same way as any other broadband router, producing a secure Wi-Fi network for your other devices to connect to. You can connect up to 64 devices to your 4G Hub with full support for Wi-Fi 5 technology (802.11a/b/g/n/ac). There are also 4 Gigabit Ethernet sockets available for connecting wired devices to your home network and two SMA sockets for attaching an external antenna if required.

The 4G Hub supports up to Category 12/13 LTE speeds (up to 600Mbps download and up to 100Mbps upload). Compared to Three’s older 4G broadband routers, it should give much faster download speeds as it has support for newer technologies like 4×4 MIMO and 256QAM.

For more information, you can see the 4G Hub specifications on Three’s website. The 4G Hub is sometimes also referred to as the ZTE MF286D.

4G Plus Hub

If you choose to pay a little bit more for 4G home broadband, you can upgrade to Three’s 4G Plus Hub router.

The 4G Plus Hub router supports a more advanced form of 4G technology known as Category 18 LTE. This means it’s able to deliver even faster download speeds in areas where the network has been upgraded.

The 4G Plus Hub is sometimes also known as the Sercomm LTE2122GR. You can find out more about it on Three’s website.

5G Hub

If you sign up for Three’s 5G home broadband service, you’ll receive their 5G Hub router.

Three’s 5G Hub is a powerful 5G router, supporting download speeds of up to 2.33Gbps. Of course, today’s 5G networks won’t allow you to benefit from the full speeds. Instead, you’ll normally get around 100-200Mbps on average, with a peak download speed of around 1Gbps (1,000Mbps).

The 5G Hub supports Wi-Fi 6 technology (802.11a/b/g/n/ac/ax) with up to 64 connected devices on Wi-Fi at the same time. You’ll also get 2 Gigabit Ethernet sockets for connecting wired devices to your home network, along with two TS9 sockets for an optional antenna.

When you cancel your 5G home broadband service, you’ll need to return your 5G Hub router to Three. This is because it is leased for the duration of the service, unlike the 4G Hub which becomes your property.

Three’s 5G Hub is sometimes also referred to as the Huawei 5G CPE Pro (H112-370).

Coverage & Availability

Unlike most other broadband internet providers, Three’s home broadband service doesn’t rely on a phone line or cable. For this reason, the locations where you can get a service from Three Broadband will be very different to other fibre broadband providers.

At present, Three’s 4G home broadband service is available in around 7.1 million UK households. This is roughly 25% of all UK homes. Meanwhile, 5G home broadband is available in selected postcodes across 194 UK towns and cities.

You can check the availability where you live by entering your postcode on this page:

In some cases, you might not be able to get a home broadband plan, even if you’re inside Three’s 4G coverage area as shown on their coverage map. If this is the case, you’ll be shown the following error message:

We’re busy expanding our network to connect more homes.

You then have two options if you still want to get 4G broadband on Three:


Three Broadband VS Fibre Broadband

The Three Broadband service uses 4G or 5G technology to deliver broadband internet into your home. This differs from fibre broadband providers who use a phone line or cable instead.

The key advantages of 4G broadband compared to traditional fixed-line broadband are:

  • There’s no need to pay for a home phone line. Unless you’d like to keep your landline for another reason, it’s possible to do away with it entirely when you’re using 4G home broadband. This can save you in the region of £20/month on line rental.
  • 4G broadband is faster to set up. There’s no need to wait for a phone line to be installed or activated. This makes it perfect for some new-build houses, or if you’ve just moved to another address and don’t want to wait for broadband to be set up. Next-day delivery of your router is available for free when you join Three’s home broadband service.
  • You can bring 4G broadband with you, wherever you go. With 4G broadband, you have the flexibility to bring your router with you to a different location. For instance, if you decide to go on a weekend away, simply bring your router with you and get an instant 4G broadband connection.
  • 4G & 5G broadband could eventually over-take fixed broadband in download speed. At present, 4G broadband is comparable in speed to a traditional fixed broadband connection. Meanwhile, the average download speed on 5G home broadband is faster than many fibre broadband services.
  • 4G broadband can be best in rural locations. In many rural locations, companies like Openreach and Virgin Media have refused to install fibre broadband due to the prohibitive costs. In such areas, it is often far more economical to install a 4G mast and to deliver high-speed broadband over a 4G connection instead.

There are also some key disadvantages of 4G broadband:

  • 4G broadband is more easily affected by network congestion and poor weather. For instance, you may see a slowdown in your connection due to poor weather conditions or due to lots of other people using the service in your area. This tends to be less of a problem on traditional fixed-line broadband services.
  • Download speeds vary depending on location and proximity to nearby masts. For this reason, the maximum download speeds of 600Mbps or 1,000Mbps can rarely be obtained in practice. You can maximise your download speed by placing the hub near to a window and installing an external antenna.
  • Latency (ping) is higher on 4G broadband. The latency (also known as “lag” or “ping”) on 4G broadband is typically about 50ms (0.05 seconds). This is higher than fixed-line broadband where the latency is typically 10-20ms (0.01-0.02 seconds). This shouldn’t noticeably affect things like browsing the internet or watching videos online, but it could affect fast-paced online gaming.
  • 4G broadband is typically more expensive. Historically, 4G broadband connections have been much more expensive than fixed-line broadband connections. On Three Broadband, the price of 4G and 5G broadband is now comparable to many fibre broadband services. However, similar 4G or 5G broadband packages available on other providers are still much more expensive than fixed-line broadband.

Other 4G & 5G Broadband Services

It’s also possible to get 4G home broadband or 5G broadband from a number of other providers:

  • EE offers 4G home broadband on 4GEE Home and 5G home broadband on 5GEE Home. Plans start from £35 per month for 100GB data up to £55 per month for unlimited 4G data.
  • BT offers 4G home broadband with unlimited data from £45 per month. You can choose from two different plans with a maximum download speed of either 15Mbps or 30Mbps.
  • Vodafone offers 4G and 5G home broadband on the GigaCube. Plans start from £30 per month for 100GB of data up to £60 per month for unlimited 5G data.

Three Mobile Broadband

As an alternative to Three’s 4G home broadband, you can get the 4G Plus MiFi instead. This is a 4G-powered mobile broadband router giving you the same underlying 4G service as on the 4G Hub.

The advantage of choosing a 4G Plus MiFi is it gives you a lot more flexibility for usage on-the-go. You can use it for up to 6 hours on battery power alone whereas the 4G Hub always needs to be plugged in at the wall. You can also use the 4G Plus MiFi in more places as Three offers 99% population coverage on 4G for this service.

The disadvantage of using a 4G Plus MiFi is it won’t be quite as powerful as the 4G Hub. You can still get Category 7 LTE download speeds of up to 300Mbps on the MiFi. However, you’ll only be able to share it with 10 devices at a time, whereas the 4G Hub allows you to share it with up to 64 devices. The Wi-Fi signal will also have a more limited range (around 10 meters, compared to 30 meters for the 4G Hub). There also isn’t the ability to use an external antenna or to attached wired devices using an Ethernet cable.

If you want the 4G Plus MiFi, you can get it on the following plans:

ServiceData AllowanceContract LengthUpfront PriceMonthly Price

Shorter 12-month and 1-month plans are also available, with a small upfront cost for the device.

  • Have you noticed many sellers on eBay, Gumtree etc are selling lots of 3 UK Huawei CPE PRO2 5G routers? Im wondering that three is not keeping an eye on their assets. Three should investigate.

    I was going to buy one but I dont want to take the risk of a blocked/ barred IMEI etc in future.

  • Hi, Ken, great site, thanks. Just a suggestion, you can update some info. Late 2021 3 UK are sending out the HUAWEI CPE PRO 2 5G hub (H112-373) for new 5G home broadband contracts. Its really good (strong antenna inside).

  • Hi Ken.

    I recently signed up for the £14 per month 4G hub but can’t use it as there is no simcard. Does the sim come with the hub or is it sent separately through the post?

    Fantastic website. Keep up the good work.

    • Hi Craig,
      Thanks for your comment. It’s supposed to come together with your 4G Hub. As you didn’t receive it, I’d recommend getting in touch with 3’s customer support team so they can send you a replacement SIM card.
      Hope this helps,
