Three offers unlimited 4G & 5G home broadband from £21/month without the need for a phone line. See how the plans compare.

In the UK, 4G technology has now developed to the point where it can be used as an alternative to traditional fixed-line home broadband.

Three’s home broadband service bring this technology to the mass market. It’s now available through this link for £21 per month, with the first six months at half price where you’ll pay just £10.50 per month. It’s also possible to get 5G broadband from £30 per month, with the first 6 months at half price so just £15 per month.

Three Home Broadband Plans

In the UK, Three currently offers two different types of home broadband:

  • Three’s 4G broadband is available from £21/month. It’s the most widely available option and has average download speeds of 14Mbps. In some places, you can access download speeds of up to 300Mbps.
  • Three’s 5G broadband is available from £30/month. Currently available in selected postcodes across 194 UK towns and cities, it offers an average download speed of 100Mbps. Speeds of up to 1,000Mbps (1Gbps) are available on the service.

The following table shows a side-by-side comparison of the two services:

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 300Mbps. This does, however, vary substantially depending on where you live. Across the country, the average download speed on 4G is around 14Mbps.

For customers wanting to replace their fixed-line home broadband connection, it’s currently possible to get unlimited 4G home broadband for just £10.50/month for the first six months. You’ll then pay £21/month for the remainder of your plan. There’s no upfront cost when you take this on a 24-month contract.

Alternatively, a 12-month plan is available for £27/month plus £19 upfront, or a 1-month rolling plan for £30/month plus £19 upfront.

When you take 4G broadband from Three, you’ll get a new 4G Hub included in the price. This is also known as the Huawei HomeFi Plus or the Huawei B535. If you like, there’s also the option of adding an Apple TV for an extra £8/month, an Amazon Echo Show 5 for £4/month or a Google Nest Audio for £5/month.

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.

Prior to September 2019, 4G broadband customers were provided with the older Huawei HomeFi router (Huawei B311).

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 £15/month for the first six months. After the first six months, it will cost you £30/month.

Three Broadband Speeds

On Three’s home broadband service, you can access download speeds of up to 300Mbps 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 14Mbps 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 new 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 network and two SMA sockets for attaching an external antenna if required.

The 4G Hub supports up to Category 7 LTE speeds (up to 300Mbps download and up to 100Mbps upload). In the past, it was also known as the Huawei HomeFi Plus or by its model number, Huawei B535.

For more information, you can see the 4G Hub specifications 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 on our way
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:

Alternatives

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 300Mbps 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:

    • Hi Roy,
      Thanks for your comment. Yes, you can keep the Huawei B535 (the 4G Hub) when your contract expires 🙂 The same isn’t the case if you get the Huawei 5G CPE Pro (5G Hub) as this is leased from Three instead.
      Hope this helps,
      Ken

  • Three is rubbish. Don’t bother. I have had sub 1Mb speed for 21 of my 24 month contract, with 2 months to go before I can stop using them. Absolutely rubbish supplier.

  • HI Ken
    Thanks for the useful information,
    Any idea if the Band you are connected to could affect your download speed !
    Am using Huawei B818 and if it’s connect to Band 20 (Three Network),, i get an average of 15 mbps, but if it’s connected to Band 3 the speed double !

    • Hi Hassan,
      Thanks for your comment. Yes, the band you’re connected to will absolutely make a big difference! I believe Three only have 2×5 MHz of spectrum within band 20 range (800MHz) so the absolute maximum speed you can get is around 35Mbps. Meanwhile, they have 2x15MHz of spectrum at band 3 (1800MHz) so you can get speeds that are up to three times faster.
      Hope this helps,
      Ken
