Without doubt this is the worst broadband service I have ever used. I have a 2 year contract for HomeFi with a Huawei B535 Router and after 2 months of suffering dropped connection, slow speeds and unable to connect to internet I gave up and bought a Virgin package again. If you are thinking of taking a HomeFi contract Do Not Do It. You will not be happy with the service. The customer service is appalling, unknowledgeable, unhelpful and could not care less about the customer. I live in a 4G high signal strenth area with 5 bars on the router signal connection. When it works correctly it does so at 15-20 Mbps, the trouble is it only works correctly for minutes at a time then drops the connection, fails to reconnect and then when it does reconnect it runs at 15-20 Kbps, the speed of a tortoise. Restarting the router makes no difference. Netflix spends all its time buffering after the initial connection and is unwatchable so their Go Binge promise for Netflix is a lie. Bottom line is that I have thrown away over £500 on a 2 year contract that is absolutely useless for the purpose. Please learn from my mistake. Do Not Use Three.

Sheffield Three Mobile  
Finally cut ties with Sky after many painful expensive years. Loved the idea of broadband w/o a landline. Never used it otherwise. Really impressed for the first 3mths on 3's pay monthly home broadband deal, just to try it out. Easy setup and great fast reliable streaming at the beginning. Rarely dropped a stream for three months. So we decided to take on a 12mth contract. Another precaution because we didn't want to get 'trapped' in any more long life-sucking contracts. Of course customer service pushed real hard for us to go for a 24mth contract instead. But I stood firm and said "No thanks!". So we stuck with the 12mth one. Well since the contract started, streaming speeds have slowed and become very inconsistent. We counted the stream drop during TV programs at least 10x during one day. That was on every device used at that time with our Huawei 4G Router 3 Pro, supposedly able to handle up to 65 devices at once. We sometimes use up to 4 at the same time. That's it. We even moved the router around and saw some improvement but only for a short while. I have a mobile with 3 and it's signal and stream are much more reliable. Why is that?? I don't hold much hope out for any vast improvement in the coming months and 3's customer service has proved to be frustrating and unhelpful. I wish somehow we could get out of it. Highly unlikely I know. But on the bright side at least it's not for 24mths. We definitely will chose someone else when this nightmare ends. I highly do NOT recommend 3 for home broadband to anybody. There are far more reliable ones out there.

River Three Mobile  
I got mobile broadband to save money in comparison to fixed line. Speeds were OK at first, but for the past year I've been getting mostly less than 2Mb and often less than 1Mb, with pages taking ages to load, and that's in the middle of a large city. I often have to use my phone to get online. Tried once or twice to contact Three, but the script is always the same, have you tried this, that...Yes I have, I'm an intelligent person and know how to troubleshoot connection speeds. I've now given up and got fibre broadband, which is not much more than Three are charging me. I'm still in contract but I don't care, I just want out. Think carefully before you go for mobile broadband for your main home connection, other much faster connections are now not much more expensive.

Norwich Three Mobile  
Rubbish service, some days it's 15mbps, some days 20mbps but to many days its 1mbps. Its not good enough and now they are trying to sell me 5g when the 4g hasn't worked consistently. I wonder if they are slowing down the 4g network to encourage people over to the 5g network?

Utterly useless. Only positive is free Netflix streaming-if you are lucky enough to have a good signal. Would never recommend three.
London Three Mobile  
Got the mobile broadband for a 12months contract. It's been poor for the last 6 months and when I finally decided to cancel they managed to talk me into it again promising a new device type after a dozen hours wasted on customer service. They sent me the same device with service beeing as poor as before. The mocking they handled my situation is incredible, all they've done is to waste my time again and again. Just now I told the guy in the live chat I just want to cancel and not waste any of my time, he asked to speak on the phone, told him I can't and I gave permission for somebody else to finish the process. They called the other person just to waste another 5 minutes with details verification and conclude that nothing can be done without the main person on the contract on the phone. I have never heard of anything similar before, Customer Service seems like a bunch of incompetents running a scam from their basement. Insane mocking and disrespect to me as a customer. Of course, I'll have to pay the full contract anyway,no matter how bad the service was for the usage period. They don't even have a capable technical team, when they called to troubleshoot my device they asked 0 tehnical questions just basic, irelevant settings matters. Insane that this company is running a bussiness in UK. Never felt more disrespected on my own dime. Don't get the service.

Joined due to the price and it definitely paid the price. Worst customer service along side the speed of the wifi Huwawie is rubbish. Never again. The customer support technical team always telling me there is no issue however takes forever to load a simple google page. Cannot watch anything on youtube as it always buffers. All pages buffer.

kingston Three Mobile  
This is the worst service I have ever had from ANY company. They didn't take payments (I turned it off as I already had Virgin broadband which was expiring at the end of 2019) I received a mail saying that I was being suspended on the 8th Jan and called them to arrange payment on the 15th (my first payday after Christmas). They said that they would and when I called them to make a payment (£70) they told me the account t was cancelled and I owed then the years payment. I offered to pay on in full to resolve ans couldn't have been more flexible but they are AWFUL. Avoid at all costs. I am currently looking at legal action and the ombudsman is backing me.

AVOID AT ALL COSTS

I bought 3's Huawei 4G mobile wifi unit on 9 January 2020. Back at my location in Acton the download speed never got above 2Mbps in the first 48 hours and there were losses of connection about every 5 minutes. When I went back to their Westfield store at 18:00 on 11 January they filed a Customer Technical Request and said that their technicians would call me within 48 hours. By 19:00 on 13 January I had not received a call from 3's technical services. None of my regular download speed checks had got above 2 Mbps in the intervening 2 days, and there were still losses of the connection every 10 minutes. I explained the problem to shop staff. They could only let me wait 10 minutes until the manager had time. I explained the problem to the manager. He called 3's customer relations department. We both sat there for 15 minutes waiting for 3's customer relations department to answer. I was then asked to explain the problem again, told that my contract could not be cancelled, and told to wait while I was passed to the technical support department. When connected, I was asked to explain the whole problem again. The technical support person then said he was passing my call to the customer cancellations department, as he could not decide on a cancellation himself. I declined to explain the problem yet again, and demanded a written confirmation of my cancellation. The technical support person said the customer cancellations department would call me back in about 48 hours.
I have cancelled the direct debit. 3 is withholding my money with insufficient grounds.

Absolutely terrible customer service. They charged me for 2 further months after I called them to say I moved, yet left me no messages. I was a loyal customer for years and now they charged me for months I didn’t use. The broadband was slow and definitely unreliable. I will never be using their services again

Lancaster Three Mobile  
Download speeds are incredibly unpredictable; very occasionally you might get 20mbps, but you usuallyget 0.5-2mpbs. Customer Service will have you move the router around, change Wifi frequency etc., but it does nothing to help the really poor consistency of their services.

What I really don't understand is my mobile provider Smarty use the Three network, and my phone gets far greater download speeds than the router sat in the window. I hotspot more than I use the Router now, which begs the question why bother paying for the service in the first place.

Easy to choose them Relish/Three in the first place due to their quick delivery/set up times, but in the end really not worth the hassle.

I thought this would solve my BB problems as i live in the countryside.
The signal drops & rises,surely i should be able to get a reliable 20meg d/load speed.Some times it drops to around 3-4 meg d/load.I need to shop around once my contract is up.

Bolton Three Mobile  
Lovely little cube for 4g internet. However, crap is all I can say. Best I've ever had was 10mb, usually it's not above 3mb. I live in a flat, however it sits on the window sill and if go further in to my flat, I can get 38mb on my mobile which is on Tesco mobile (using O2 network). When I bought it, 5g was rolling out the followimg week, that was in July and 6 months later, I'm still getting 1mb of 4g.
Cannot wait until my contract finishes. P.s. this was written on my mobile data as the wifi waste slow

Have had broadband supply from 3 for 2 months, during that time we have lost signal numerous times, for up to 5 days. Customer service is appalling, do not seem to care, say someone will contact within 2 days, and will try and get signal back within 7. Have never had any problems with previous suppliers. Only have 1 stars because you cannot give none.

East London Three Mobile  
Absolutely ****** service, I was told by their website that 4G and 5G are available in my flat and that internet speeds were a minimum of 20Mbs.

Once I received the device it wasn't even receiving 4G, the maximum speed I received was barely 700 Kbs ( emphasis on the K ). After calling customer service, I was answered by an inexperienced technician in a different country that was reading a pre-set script and had absolutely no idea about what he was talking about.
His main recommendation: " Put the device next to the window it will work have a better signal "

Being desperate for Wifi, I opened the window and put the device almost outside which is when I finally reached a speed of 1Mbps ... I decided to cancel the service afterward and was told by the company to send the Hub back by post, they also had the nerve to tell me that If they do not receive the device or if it was damaged I would be charged with a 350£ penalty ( For a ****** Huawei Hub that does not cost more then 20£ )

I DO NOT RECOMMEND AT ALL

i live in very rural west sussex. My talk talk broadband -fibre, was peaking at about 27mb. Then my price went up out of contract so i switched. I had looked at mobile as i knew the mast was only about 1 mile away and was 4g+ enabled. I am an existing 3 customer so knew i had coverage. I bought the alexa enabled Huwawei AI cube and pay £20 a month. i am getting a connection of around 90mb now. There is a cap of 1TB per month so keep your eye on your usage, you can do all of this on your phone with the app. if you have doubts, simply tether your existing phone to your pc/laptop/firetv stick etc and see if it works before you order the hub. Its excellent, the hub, and has alexa and a nice bass speaker in there so you can pair your devices to it for sound as well.Much better and faster than wired broadband out here in very rural west sussex.

Horrible horrible broadband. As a user I have never been so helpless. Three broadband charged me double the bill in one month. When I asked for help on customer care, they made me wait for 40mins and I am kidding. When I went to the store they asked me to call the customer care. Horrible and pathetic service. Never ever opt for this please if you want to stay in peace.

Our Three signal is good (looking at other reviews not everyone checks first). We are in a semi rural area so congestion should not be much of a problem. So far internet speeds have averaged 40-50 MBS, fine for 4k streaming. There is a bit of a lag as you start up, most of our speed tests point out this would not be good for gaming. Our previous fibre was not half of this due to distance from the centre. Reliability has not been 100% with a few days of poor service but compared to BT its about the same. Data transfers, especially uploads, have been extremely quick.
Customer service has been challenging at times, you get get the "we want to help you" type of approach but few will understand exactly what you are saying.
We have the Huawei AI cube (more of a cylinder really) which supplies the whole house fairly well. I use an Ethernet cable for the TV which seems much better for stability than wifi. I had a go at range extending but there seems to be an incompatibility with my tp-link plug in system. I have simply moved the antennas on my remote computer.
All in all very happy so far.

Caterham Three Mobile  
We have it for a couple of months. It was okay in the first month and now is extremely slow most of the time (downloading 81Mb software update in 10 minutes) and not reliable (sometimes okay but most of the time have to wait ages to load a page) . When we signed up we were told in the shop that if it will be too slow we can end the contract earlier but customer service told me not possible. Last 2 weeks were the worst and I spent numerous hours to get to the customer service by phone and the connection kept breaking. I would not recommend this as a main home broadband, maybe as a back up or when there is no other options.

Very sad though, used this company for mobile phone for several years but broadband - definitely no!

South Croydon Three Mobile  
This company bought Relish broadband and when I moved house recently I tried to call to cancel the account. I had to call multiple times and wait on hold for over 40 minutes each time, only to be told they couldn't locate my account, despite me giving all the information. They told me to call another number which disconnected no matter what selection I made. I called back. I chatted with advisors online. I called back again. I went to a physical store, where they couldn't do so much as look up my account information. Finally after more than a week of trying to sort it out, I am told I can cancel but I will be charged for an extra month of services, because I didn't cancel one month in advance. What a rip off. Not only that, but the service was unreliable and pages took a long time to load. I liked Relish but Three is a corporate and bureaucratic maze and I can't recommend them to anyone on customer service (or lack thereof) alone.

Had 2 years good service, last month it stopped,a month latter after being tied into another 24 month contract with the promise the better router would work, still no internet, no exaggeration 30 phone calls latter hours on the phone, more lies than would be believed from the technicians and network team ie, were working on it,the account is set up wrong, the sim card is faulty,give us a week while we work on the mast, we will phone you back, etc just a few examples, they are trained to lie so to close the case down, I have never met such a bunch of liars,and hope never to come across this company again, your ok if things work, but if you have to contact them beware,it seems they take pleasure in your stress and make life very difficult, got through to customer relations today to be told we cant provide you with a service because we've upgraded to 4/5g and that's not in your area, and wont be mainting the old equipment where you were getting your signal from.

We bought this because of the immediacy - as opposed to waiting for installation. My advice: ALWAYS WAIT FOR INSTALLATION OR SEEK ANYTHING ELSE. This device is absolutely awful, genuinely the worst internet provider I've ever used. The people on the lines for customer service are really good but it ultimately does not matter because the product itself is categorically useless. I've had it for seven months - in which time I've moved three times - and every single place I've used it, it has varied been working extremely slowly - or not at all. Seriously, do yourself a favour and steer clear of this one.

Crap, don't get it. Highly recommend you look else where.

- Unstable as ****
- Connection dropping
- Not suitable for anything other than youtube which if you're lucky it might only buffer once. (IT'S 2019!)
- Sounds too good to be true, save your money...

Gloucester is not a good area for broadband and BT does not provide a fibre service in my area so I can't use Sky which I would like to. I could have Virgin Media but they are expensive and unreliable..
Three broadband is steady, I have unlimited and it is reasonably priced at £27 pm. Signal strength varies a lot so I use the personal hotspot on my iPhone which is also with Three. Strength is around 18mbps.
Any information you may have about BT providing a local fibre service would be great.

Overall my experience with Three has so far been positive. The only problem is the broadband speed during the day in my area which can drop down to 1.5 Mbs/s while at night it is usually between 20 - 30 Mbs/s.
The customer service has much improved over the years in my opinion. Well done Three.

Middlesbrough Three Mobile  
I've had a very positive experience so far. Far better value for money than my old network and coverage seems a lot better as I no longer experience grey areas of poor signal.

The customer service has been good, I've only messaged them once but they gave a quick and helpful response. It was easy enough to activate the sim and move over my number. Roaming also works smoothly - I've used it in Spain recently and my 4G was working as normal the whole time and with no extra cost.

I had been with Three for some years and found it reliable and cost effective despite some signal drop out issues. I had a £10 per month unlimited texts and calls and 4GB data plan which suited me fine. That was until I got a letter from Three to say that, since my 12month contract had finished they were changing me to a monthly rolling contract for the same service but at £14 per month!!!

I went to my local Three store (Bloomfields Shopping Centre, Bangor, Northern Ireland) and spoke with the store manager, a most unhelpful individual. He told me, quite plainly, that my options were to take it or leave the network. I chose to leave the network but now wish I hadn't.

I found a deal with SMARTY, a wholly owned division of Three, giving me what I had at the price I had been paying and with a monthly contract. I initiated the changeover but quickly ran into issues, not least with their useless customer services agents. I instructed them to terminate the transfer process as they had frustrated me. They assured me it was terminated and I resolved to find another deal.

But they hadn't terminated, the transfer carried on and I was cut off from Three then cut off from SMARTY and left with no service! I had to go back to Three on a whole new deal and get a PAC code from SMARTY to get my old number back.

I gave the PAC code to Three, was told the usual 1 to two business days for transfer and waited. Nothing happened. I contacted Three customer services (SAVE ME from Indian call centres!!) to be told there had been "an issue" with the PAC code so they started again. Three days later, still no transfer so I called them again. Another "issue" with the PAC code so it was started again!

Now, after the third attempt, it's still not done!! And their customer services do nothing but ask the same questions again and again and make the same empty promises again and again. And so, 7 days later, I still have not had my original number transferred back. USELESS!
