What is Mobile Broadband?
Mobile broadband is the best way to keep your Wi-Fi enabled devices connected when you’re on the move or if you don’t want to deal with wired broadband. Mobile broadband gives you the ability to bring your internet anywhere and take advantage of the fast data speeds now offered by mobile network providers.
Mobile broadband deals require a data SIM and a wireless router in order to provide internet access. Three offers a wide variety of data SIMs, as well as mobile devices like handsets and tablets.
You can connect multiple Wi-Fi devices to your wireless router, letting you game, stream or download files wherever you go. You can also share your connection with friends and family. Three offers two wireless routers at the moment: 4G+ MiFi and Huawei HomeFi (Huawei B311).
Mobile broadband works in pretty much the same way as creating a personal hotspot with your handset, but it offers stronger signals, better coverage and significantly more reliable internet connection.
How does Mobile Broadband work?
Mobile broadband uses a data SIM card that goes into a wireless router or a tablet. Most modern tablets usually have a data SIM slot, but they’re not as capable as wireless routers when it comes to distributing the mobile internet to other devices. If you want to connect multiple devices to one data SIM, wireless routers are the best way to do so.
You can stay connected as long as you have access to a strong mobile signal and network coverage. Mobile broadband eliminates the need to find a Wi-Fi network, if you’re on the move a lot. When you have coverage and are connected to Three’s network, a mobile Wi-Fi router can create a portable Wi-Fi hotspot that can be used to connect multiple wireless devices. If you choose the Huawei HomeFi router, you can also use a wired connection.
Thanks to mobile broadband you can establish a secure local area network within your property, and without the need for a fixed line.
Plans & Pricing
Pay Monthly Mobile Broadband Data SIMs
In the UK, 4G technology is constantly improving and changing for the better. This means as long as you get good coverage, 4G can deliver download speeds that are comparable to home broadband, or sometimes even faster. Three’s mobile broadband deals only deliver 4G speeds at the moment, but we expect the network to offer 5G download speeds as the network’s 5G coverage gets wider in the UK.
Three currently offers 1-month, 12-month and 24-month contracts for mobile broadband. You can get an unlimited data plan dubbed ‘All-you-can-eat’ starting from £22 a month, but you’d have to sign up for a two year contract.
You can use your allowances to call and text home and use your data in 71 destinations worldwide, just like you can with Three’s SIM only deals.
Three offers more than 20 mobile broadband plans, and you can bundle your choice of plan with a Huawei 4G Plus WiFi or Huawei HomeFi (B311) wireless router. Alternatively you can purchase a tablet with your plan too.

Mobile Broadband Wireless Routers

Huawei HomeFi (Huawei B311)
Huawei’s B311 Wireless Router gives you access to the internet through a mobile connection and ethernet/network cables. You can connect to this router using a network cable or Wi-Fi and get high-speed internet services from Three. Just keep in mind that your download speed can vary depending on multiple factors, the key one being how good the coverage in your area is.
The Three HomeFi router comes with a 4G data SIM card, so all you have to do is pop the card into the back of the router, and switch it on. The router will set up everything automatically and you’ll have access to the internet in no time.
If you’re looking to purchase this router from Three, you don’t have to sign up for a long-term contract. You can stay with Three for as little as 1 month. Huawei HomeFi also supports up to 32 Wi-Fi devices at the same time.
If you want to change the Wi-Fi settings, you’ll need to connect your HomeFi router to your PC first.

Network Coverage & Data Speeds
4G Coverage & Data Speeds
Three is a major network operator in the UK alongside EE, O2 and Vodafone. This means they have their own infrastructure and are not using another network to provide coverage. The network provider doesn’t offer any 2G coverage, but it’s not important in this case anyway, as 2G is not capable of delivering data to support mobile broadband.
Three offers over 99% 4G population coverage, however, in terms of landmass coverage the network is lagging behind its competitors. They are constantly improving their 4G network, but at the moment you might experience problems, especially in rural areas. You can have a look at our extensive Three Review to discover more about the network.
On the other hand, in terms of 4G data speeds Three is doing quite well. According to Open Signal’s October 2020 speed test results, Three’s average 4G download speeds are around 22.2Mbps, and upload speeds are at 8Mbps. This means their data speeds are on par with Vodafone, although the latter offers better coverage in rural areas and offers slightly faster 4G data speeds than Three. Vodafone still ranks second when it comes to data speeds, but the gap between the two is insignificant for the end user. We prepared an in-depth Vodafone vs Three comparison, if you want to discover more and see which network offers better perks, coverage and features.
EE is the fastest 4G network in the UK and they also have the best network coverage. The network’s average 4G download speeds are at 36.4Mbps and upload speeds are at 9.1Mbps. Check out our EE Review if you want to discover more about their SIM deals. You can also check out our EE vs Three comparison.
5G Coverage & Data Speeds
Currently, Three’s mobile broadband deals don’t come with 5G coverage. It’s understandable given how 5G isn’t available country-wide yet. However, if you have Three’s 5G in your area you can get a Three 5G Home Broadband deal.
Three’s 5G coverage in the UK is live in 68 cities and towns at the moment. The network has the best 5G infrastructure and more spectrum than all the other major networks. Looking at OOKLA’s (speedtest.net) network test results we see Three ranking at the top of the table when it comes to download speeds. Three’s average 5G download speed is at 201Mbps, this means they’re the fastest 5G network in the UK at the moment.
You might also want to see which networks offer the best 5G SIM only deals, and we’ve got you covered with our in depth article.
Tethering refers to turning your phone into a personal hotspot. This way you can share your mobile network data (internet connection) with other Wi-Fi devices. Obviously, when you have a wireless router you don’t have to worry about tethering as you can share your internet connection with as many devices as your router supports.
However, if you wish to extend the range of your mobile broadband, you can still use your handset’s tethering feature and create your own range extender. We strongly suggest going with an unlimited plan or at least a large data plan, if you’re planning to use multiple devices on a regular basis. You can read our “How much data do I need?” guide to figure out the ideal plan for you.
You can use your Three mobile broadband in 71 roaming destinations around the world. This includes most of the highly travelled EU countries, as well as USA, Australia and many other popular worldwide destinations. You can click here to see the full list.
Both pay monthly and pay as you go mobile broadband customers get the same pricing and Go Roam benefits, unless there’s a special offer. When you are travelling outside of ‘Go Roam’ destinations, please make sure to check the rates for your destination in advance.
Half Cooked’s Overall Breakdown
Three Mobile Broadband is a decent choice and will get you comparable download speeds with a regular landline connection. Your download speeds will vary depending on how good your 4G coverage is and how many people in the area are also using the same network as you do. In ideal scenarios you can get up to Category 7 LTE speeds with the MiFi router (all the way up to 300Mbps download speeds & 100Mbps upload speeds), but in most cases you’ll get around 20 to 30Mbps.
When the coverage is far from ideal, your connection might drop and your download speeds can go as low as 1Mbps. However, this isn’t a problem unique to Three, as all mobile broadband deals can experience the same issues.
Half Cooked’s overall rating for Three Mobile Broadband: (3.5 / 5)
