The Three 4G Plus Hub, available in the UK from Three, is a 4G router that enables you to access the internet. Like your cellular device, this router uses a 4G signal instead of a landline connection.

Configuring home internet with the 4G Plus Hub is simple – all that’s required is to slide the SIM card in, attach the antennas, plug it in, and switch it on. There is no need to hire an engineer to come to your residence or to pay for the rental of a landline telephone.

You can have internet access from almost any location in the UK as long as there is 4G coverage with the 4G Plus Hub.

After you finish the setup process, the 4G Plus Hub (a renamed Sercomm LTE2122GR router) will create a wireless network, like the regular home internet routers you may have used, and can be connected to any of your devices.

The Hub provides 2 Ethernet ports to connect computers and gaming consoles using a wired connection.

With the 4G Plus Hub mobile broadband router, you can access unlimited data, a feature you usually find in-home broadband packages. You don’t need to worry about extra charges or usage restrictions.

Three’s 4G Plus Hub is similar to its standard 4G Hub.

4G Plus Hub Vs 4G Hub

Three 4G Plus Hub review

There are some noteworthy distinctions between the 4G Hub and the 4G Plus Hub: 

  • The 4G Plus Hub is often quicker in actual use since its external antennas furnish a more powerful 4G signal.
  • The 4G Plus Hub is more substantial and has a bulkier appearance, particularly when the antennas are attached.
  • The 4G Plus Hub is capable of faster download and upload speeds than the Cat 12/13 model, with a maximum theoretical rate of 19/20.
  • The 4G Plus Hub includes only 2 LAN ports, not four.
  • According to my experience, the 4G Plus Hub has a slightly stronger Wi-Fi signal than usual. I observed that the connection was much more stable when using the network over longer distances.

Interestingly, the price of the 4G Plus Hub is the same as the standard 4G Hub right now.

How The 4G Plus Hub Is Sold

Before purchasing the 4G Plus Home Broadband Hub, enter your postal code into the Three websites. The 4G signal is strong enough to enable the router to function correctly at your residence.

Three 4G Plus Hub comes with a 2 year pay-monthly contract with unlimited data and no initial payments. As of now, no pay-as-you-go plans are available.

When you purchase the device, you have to use it for the next two years. You get a 30 day money-back guarantee, allowing you to find out if you get the fastest speeds in your area.

If the device does not meet your requirements in terms of speed or has any connection issues, Three will provide you with a pre-paid envelope to send it back.

After you have placed an order, the 4G Plus Hub will be delivered within 1-2 business days.

Three 4G Plus Hub Review: Unboxing And Setup

Three 4G Plus Hub review

4G Plus Hub arrives in a Three branded box. When you open the package, the wireless router is first visible.

This router is of adequate size, both too big and too small, and has limited weight.

On the back, you’ll see: 

  • Home phone port
  • Power button
  • The label comes with Wi-Fi and admin page login credentials
  • 2 LAN ports
  • 2 external antenna ports (behind the circular rubber protectors)
  • Factory reset button

On the front side of the device, you can see the indicators of the system’s status. They generally appear green but can also take on an amber or red hue in specific conditions. For instance, the 4G light will become red if there is no 4G connection or the SIM card isn’t inserted.

At the highest point is a button labelled WPS that connects to a wireless network and a Wi-Fi button that activates or deactivates the Wi-Fi network.

A pair of 4G antennas are beneath the router that comes in their packets that can be attached to the router to acquire a better 4G signal. You will need to connect a power cord to the router in the future.

Now comes the setup process of the Three 4G Plus hub review: 

  • Obtain the SIM card package. You need the Micro SIM. Be careful not to push out the smaller Nano SIM.
  • Next, unlock the panel on the side of the router and insert the SIM card with the Three logos facing the back of the Hub. You don’t need to push it in too far – you’ll hear a sound when the SIM card is inserted correctly. Once done, close the cover back up.
  • Install the two external 4G antennas.
  • Remove the antennas from their containers, then extract the rubber guards from the antenna jacks. This can be rather challenging when you do it for the first time.
  • You can twist the antennas into place by using the wide parts on the sides. Make sure to stop when the gap in the centre faces upwards, and the antennas are pointed toward the heavens.
  • Once the antennas are set up, plug the power cable into the router and a wall outlet, then activate the mobile broadband device by pressing the button at the rear.
  • Currently, the 4G Plus Hub will need some time to initialise. You will know you are connected once the 4G signal light turns green.
  • You can access the internet by using the login credentials printed on the reverse side of the router or by pressing the WPS button at the top.

The most suitable spot for the router is usually a windowsill on an upper floor (if available) to achieve the strongest 4G connection.

Undertake some experiments with the 4G home broadband router at various locations to evaluate which one yields the most reliable connection and highest download speeds.

Three 4G Plus Hub Review: Speed Test

Three 4G Plus Hub review

I experienced typical download speeds of around 150-175 Mbps and upload speeds of 7-10 Mbps with the Three 4G Plus Hub connected via Wi-Fi.

When I employed an Ethernet link, I acquired similar outcomes using Wi-Fi, but my ping time was usually lower, and my rates were more stable. Occasionally, the rate of my internet connection via Wi-Fi would decrease to 75 Mbps, and the latency would reach up to 35ms.

I am in an ideal spot to utilise the 4G Plus Hub. The nearest 4G base station is within a short distance, situated high up, and there is hardly any 4G blockage in my locality.

I devoted a lot of time trying different places for the 4G+ Hub to ensure it was in the right spot to get the strongest 4G signal.

Your Three 4G Plus Hub may give you different speeds than I saw. But, you should get a download speed of 50-100 Mbps if you have an excellent 4G signal.

4G Plus Hub Speed At Your Address

The rate at which you receive 4G Plus Hub from Three is subject to various conditions, such as your location, router location, and other contributing elements.

Generally, users can anticipate download speeds of around 50 Mbps when using the 4G Plus Hub, while uploads will be 5-7 Mbps. If the 4G reception is strong, it is possible to get download speeds of over 200 Mbps.

To determine the speed of the 4G Plus Hub, use the Three network coverage map. Insert your postal code into the map and decide whether or not you have good indoor and outdoor coverage at your residence.

If you get solid 4G coverage, anticipate download speeds of less than 30-40 Mbps and possibly far faster.

It is possible to check the performance of the 4G Plus Hub by taking advantage of Three’s 30-day returns policy, which is quite generous.

Three 4G Plus Hub vs 4G Hub vs 5G Hub speeds

My assessment determined that Three’s home broadband options yielded the following maximum download speeds:

  • 4G Hub offers 199 Mbps
  • 4G Plus Hub offers 290 Mbps
  • 5G Hub offers 721 Mbps

Some modifications to my region’s 4G LTE system may have caused the speed boost since I examined the regular 4G Hub a few months ago.

Three 4G Plus Hub Review: Gaming Test


I tried out the 4G Plus Hub via Ethernet with a few online games: 

Generally, my latency was approximately 35-40 milliseconds to the closest game servers. My ping usually is 20-25 milliseconds with my ordinary home internet service.

Despite the increased ping measurement, I didn’t notice any considerable delays or peaks in ping. Every game was fully playable, even when playing competitively.

The 4G Plus Hub is an excellent option for gaming, mainly if you link up your computer or console with an Ethernet cable. Although, the latency is usually a bit higher than what you would get with fibre broadband.

Three 4G Plus Hub Review: Value For Money

Three 4G Plus Hub is an excellent investment due to the following factors: 

  • There is currently no upfront fee available.
  • If you obtain a normal domestic internet package offering comparable download rates, the monthly cost would be significantly higher.
  • You get a 30 days money-back guarantee with 4G Plus Hub, meaning you can test it without risk.

The Three 5G Hub has the same price tag as the 4G Plus Hub, although its speeds are much higher. This makes the 4G Plus Hub seem overpriced, despite it not being so.

If you reside in a strong Three 5G signal area, getting the 5G Hub is a good idea.

Three 4G Plus Hub Review: My Verdict

Three 4G Plus Hub review

I find the 4G Plus Hub very appealing for the following reasons: 

  • The Wi-Fi connection is excellent, far superior to the 4G Hub, and capable of transmitting data rapidly, even within a large residence.
  • The significant advantage of this 4G home broadband plan is that you do not have any data restrictions.
  • Obtaining the 4G Plus Hub is far more affordable than most fibre broadband offerings in the UK that provide download speeds from 50-100 Mbps or higher.
  • Even though it’s not as effortless as the 4G Hub, installing the antennas still makes it quite effortless to configure.
  • It is possible to utilise this 4G router all over the United Kingdom with Three 4G reception, not just in a residential setting.

The 4G Plus Hub is not flawless: 

  • Setting up the antennas isn’t a significant challenge, but it requires some time – taking off the rubber covers can be difficult.
  • Locating the ideal place in your residence to receive the highest speeds can be challenging.
  • When you are playing online games, the response time may be slower than normal, and the connection speed may not be as steady as what you would experience with a residential internet package.

The 4G Plus Hub generally makes an excellent home internet setup for most households. It provides ample bandwidth if there is a solid 4G connection. The most impressive aspect of the 4G Plus Hub is its excellent cost, providing superior value for the money.

I rate the 4G Plus Hub 4.7 out of 5 – It presents an affordable, expeditious, and effortless solution to establish an Internet connection in residence.

Three 4G Plus Hub Review: Alternatives

Besides the Three 4G Plus Hub, several other gadgets offer you the possibility to access the internet through mobile broadband, such as 4G or 5G. Here are the alternatives of the Three 4G Plus Hub review: 


Three 5G Hub

Three 4G Plus Hub review

When you input your zip code into the Three websites, they will direct you to the 5G Hub rather than the 4G+ Hub if 5G coverage is available in your area.

It is advisable to purchase the 5G Hub for two primary causes: 

  • It is possible to obtain this on a recurring monthly basis.
  • You can experience 5 times faster download speeds.

The 5G Hub is usually priced the same as the 4G Plus Hub, making it an excellent deal considering the speed it provides.

Three 4G Hub

Three 4G Plus Hub review

If you are not interested in configuring external antennas or want a lighter and more compact mobile broadband device, the standard 4G Hub is an excellent selection.

Despite minor variations, the 4G Hub is almost identical to the 4G Plus Hub, with the same price tag and basic functioning.

An advantage of this device is that it has a higher number of Ethernet ports (four instead of two) and is extremely easy to install. Unfortunately, its Wi-Fi strength could be stronger.

Three 4G+ MiFi device

Three 4G Plus Hub review

The Three Huawei 4G+ MiFi unit is not as effective as their 4G+ Hub router when it comes to broadcasting a Wi-Fi signal – it can just support up to 10 gadgets to access the web simultaneously.

The major benefit of this MiFi device is its convenience. It has a battery, so you don’t have to keep it connected to a power source, allowing you to access the internet virtually anywhere as long as there is a strong 4G signal.

Three MiFi has a great selection of data plans, including pay-as-you-go and unlimited data plans. Even though it is a smaller device, it still provides perfect download and upload speeds.
