Three Home Broadband Review (Updated 2026)
Cheap 5G Internet or Unreliable Signal?
Three is still one of the cheapest ways to get home broadband in the UK if you have decent 5G coverage. You plug in a hub, skip the engineer, and get online in minutes. The catch has not changed though. Because this is wireless broadband, your experience still depends heavily on signal, congestion, and where you put the hub. For renters and short stays it can be brilliant. For people who want fibre-like consistency, it can still be a bit of a gamble.
Pros and Cons
What It Nails
-
Excellent Value Three is still one of the cheapest ways to get genuinely fast broadband at home, especially if your postcode qualifies for the current 24 month promo.
-
Plug and Play No engineer visit, no drilling and no waiting around for activation. The basic setup is as simple as broadband gets.
-
Properly Flexible There are still 1 month rolling options if you do not want to commit, which makes Three great for renters, students and short stays.
-
Outdoor Hub Option If your indoor signal is poor, Three now has an Outdoor Hub with an eero router, which gives awkward properties a much better shot at stable 5G.
The Drawbacks
-
Signal Still Rules Everything Speed can swing a lot depending on time of day, local congestion and where the hub sits in your home.
-
Gaming Is Not Fibre-like Casual gaming can be fine, but ping and jitter still tend to be less predictable than on a decent full fibre line.
-
Hub Features Are Basic The supplied kit is decent enough, but power users may still find the settings and controls a bit limited compared with a proper enthusiast router.
-
Advanced Networking Can Be Fussy If you need hosting, remote access or very specific NAT behaviour, mobile broadband can still be awkward compared with fixed line broadband.
The Concept
No Cables, Just Signal
Traditional broadband relies on copper or fibre physically running into your property. Three Home Broadband does not. It uses the same mobile network as your phone to bring internet into your home through a 4G or 5G hub.
You get a router with a SIM inside, plug it into the mains, and it pulls signal from the nearest mast before turning it into Wi-Fi around your home. That means no landline, no engineer, and no installation faff. It also means your experience depends heavily on coverage, congestion, and where the hub is placed.
Hardware: The Hubs
The Standard Hub and the Newer Outdoor Option
Three’s regular 5G Home Broadband hub is still the simple option. Plug it in, wait for the signal to settle, and you are away. The current 5G kit supports Wi-Fi 6, which is good enough for most homes and a clear step up from the old basic-box era of mobile broadband.
The bigger update is the Outdoor Hub. If your property struggles to pull in a decent indoor signal, Three now offers an external unit that sits outside and connects to an indoor eero 6 router. That is genuinely useful, because it gives homes with awkward walls or weak line of sight a stronger chance of getting usable 5G broadband without giving up and going back to fixed line.
Whichever setup you get, placement still matters. On mobile broadband, a small change in position can make a surprisingly big difference to speed and stability.
My Real World Experience
Finding the Sweet Spot
Three’s coverage checker said I had good indoor 5G where I lived, but the real selling point for me was the flexibility. I could get a 1 month rolling plan for just under £30, which was ideal because I genuinely did not know if I would stay in the flat for long.
This was a couple of years ago when I was living in a top-floor apartment. The building came with EE, but the Wi-Fi situation on the top floor was awful, so I needed a quick alternative that I could sort myself.
For general internet use, Three was absolutely fine. Day-to-day browsing, streaming and downloads were smooth enough, and it solved the basic problem fast. That is still what I think Three does best. It is not fancy, but it gets you online quickly and cheaply when the signal behaves.
The only issue was consistency. It could be a bit up and down depending on the time of day and where the hub was placed, which you notice straight away if you are used to the steadiness of a proper fixed broadband line.
Gaming Frustrations
Gaming was the one area where it did not really shine. On my gaming PC, playing Call of Duty was never the best experience. Sometimes it was okay, but the connection just was not consistently steady enough for a fast-paced online shooter.
Even when everything else felt fine, I would get the odd stutter or weird spike that you really notice mid-match. If you are a casual player, you could probably live with it. If you are competitive or you are used to full fibre, you will probably get annoyed.
The Packages
Three has kept the range pretty simple, which is honestly part of the appeal. You are mostly choosing based on contract length, coverage and whether your home needs the standard hub or the Outdoor Hub.
Current Options Worth Knowing About
12 month 5G Home Broadband: At the time of writing, this is listed at £24 a month. That rises to £27.50 from 1 April 2026, then £31 from 1 April 2027. It is a decent middle ground if you do not want to lock in for two years.
24 month 5G Home Broadband: This is the standout value option right now. Three is advertising it at £11 a month as a half-price promo, with the higher pricing not kicking in until later in the contract. If your address qualifies, that is hard to ignore.
1 month rolling broadband: Still available if you need flexibility over the lowest price. It is one of Three’s biggest advantages for renters, students and anyone in temporary accommodation.
Outdoor Hub: If indoor 5G is shaky at your place, Three now sells an Outdoor Hub on a 24 month plan at £21 a month. It comes with an indoor eero 6 router and is a much better fit for awkward properties than hoping a standard hub will magically behave.
Performance & Speed
By The Numbers
Three currently advertises average 5G Home Broadband download speeds of 150Mbps. That is solid on paper and perfectly fine for streaming, hybrid working and big household usage, but it is still an estimate rather than a guarantee. Local congestion, walls, mast distance and hub placement all matter.
For most people, the speed is not really the problem. The bigger issue is consistency. Three can feel brilliant one hour and merely fine the next. If you mostly stream, browse, work from home and want unlimited data for a good price, it makes sense. If you care about absolutely stable latency, fibre is still the safer bet.
Top Alternatives
If you are not sold on Three, here is where the main alternatives make more sense.
The Full List of Extras
Three is still leaning hard into value, but there are a few extras that make the overall package more attractive than the headline price alone suggests.
-
Three+ Rewards: Home Broadband customers can still access Three+, which includes rotating offers, cinema deals, coffee freebies or discounts when available, and presale ticket access.
-
Switch Credit: The current 24 month Home Broadband offer includes a switching incentive of up to £200 credited back against your last bill from a previous UK provider, which is a nice bonus if you are moving across anyway.
-
30 Day Money-Back Guarantee: This is still one of the best things about Three. Wireless broadband is postcode-sensitive, so having a month to test it properly takes a lot of the risk out of the decision.
-
Fast Delivery and Easier Switching: Order before 8pm and Three says it can offer next working day delivery. It also supports One Touch Switch if you are moving broadband provider and want the admin handled more cleanly.
The Trade-Offs
Before you sign up, there are a few mobile broadband quirks you should go in with your eyes open about.
Port forwarding and NAT can be awkward: If you are the sort of person who needs remote access, hosted services or very specific router behaviour, test carefully during the 30 day return window. Mobile broadband is not always as straightforward as fixed line for advanced networking.
Congestion is real: You are sharing nearby network capacity with other users in the area, so speeds can dip in the evening or during busy local periods.
Signal is a house-by-house thing: Good postcode coverage does not guarantee a great result in every room. Older walls, modern insulation and the exact direction of your windows can all affect performance more than people expect.
Ownership & Structure
VodafoneThree
Three UK is now part of VodafoneThree after the Vodafone UK and Three UK merger completed on 31 May 2025. VodafoneThree is 51% owned by Vodafone and 49% by CK Hutchison. Three still exists as a consumer brand, but it now sits inside that wider joint venture.
FAQs
Do I need a landline for Three Broadband?
No. Three Home Broadband works entirely over the 4G and 5G mobile network. You just plug the hub into a power socket and it connects wirelessly, so there is no landline rental to deal with.
Is Three 5G good for gaming?
It can be decent for casual gaming, especially if your signal is strong, but it is still less predictable than full fibre. Download speeds are often more than good enough. The real issue is latency and jitter, which can still wobble around.
Can I take the hub with me if I move?
Yes. That is one of the main benefits. As long as your new address has usable Three 4G or 5G coverage, you can unplug the hub and use it there without booking an engineer.

Broadband & Technology Expert
"Three Home Broadband still makes the most sense for renters, students, short lets and anyone lucky enough to live in a strong 5G area. It is cheap, quick to set up and genuinely flexible. The newer Outdoor Hub also makes it more viable in trickier homes. But the basic truth has not changed. If you need rock-solid consistency for competitive gaming, hosted services or critical work calls, a good full fibre line is still the safer option."
