    I have written probably just one bad review in my life and only because it was really bad, this is the second one.
    The first thing is their customer service. I have been using broadband from Relish for 4 years before Three took over. I have never had any problems with Relish. I used to have nearly the full signal.
    I live near Holborn and not so long ago my signal dropped to the minimum and my internet basically doesn’t work.
    When I made a decision to move here, due to some circumstances Relish was my only option and still is. I was basically dependant on it. Now, it caused me loads of troubles.
    When I called the customer service, my call was transferred 4 times and they asked me the same questions. It was a mess. When finally somebody decided to talk to me, they were asking me some random numbers and information. It seemed like they had no idead what are they talking about. At the end I was told that my broadband is not registered and that I can’t be helped. RIDICULOUS!! Despite the fact I was paying my bills and using my broadband before. I gave up really frustrated and tried to call them again later.
    This time I wasn’t transferred. Their support guy, who seemed like he knew was he was doing, managed to find my account without issues and started looking into the problem.

    Not here comes the second part. I was told that one of the cell towers was removed and there is nothing he can do. Without ANY warning. No emails, messages NOTHING. What a disgrace to their customers!!! I have never experienced anything like that in my life. That’s how they value their customers. I asked to speak with somebody higher and I was told that it is not possible. It wasn’t his fault, so I didn’t want to vent my anger on him. Until now I am still struggling to find a replacement. I have already had some problems with Three before. Now, I am changing my mobile network too. I have heard some bad stuff about them from my friends and I was warned. I think I have learned my lesson. The most people I know have a different one or are changing their network.
    I hope that this will help the rest of you who are still deciding to or not to go with this company and I strongly recommend to AVOID it. For some people it may work, but once you start having some problems, you can’t rely on them at all!!! It seems like you are secondary or none to them.

    I thought I would give Three broadband a try as our landline broadband contract is nearly due for renewal and we have had several week-long outages due to broken overhead phone lines.

    The kit arrived quickly and was easy to install.

    However the data speeds were very erratic.
    At one point I was seeing 40MB/s+ download and 35MB/s upload speeds with an acceptable 36ms ping. Had the performance kept at this level it would have been brilliant as this outperforms our current FTTC broadband. But the above speeds were very much the exception. Without any change in the router location or obstructions, speeds would drop to less than 3MB/s with pings close to 100ms. Also, the system would not allow my son's XBox to download games or updates, throwing out an error message on every attempt. When I contacted Three technical, the only solution they could come up with was to force the router into 3G mode. At that point data was flowing at a snail's pace and it wasn't even possible to view BBC iPlayer.
    I even tried a quality LTE Mimo external antenna as we are some way from the nearest mast. This did improve signal quality, but the speeds were still all over the place.
    I didn't want to be stuck in a 2 year contract so decided to pull the plug on the trial within the 14 day cancellation window.
    A shame really and perhaps if we were closer to a cell mast, it would have been more reliable. But it wasn't a workable solution for us.
    By the way, I think you only get the 14 day cancellation option if you buy on line. Not from a store. So if you are thinking about Three Broadband, my advice would be to take out the contract on line, then you can test and reject it, if it isn't working to an acceptable level.
    Customer service was OK throughout the whole experience, but at the end of the day the broadband just wasn't reliable or fast enough.

    Three deliberately throttles internet speed and then uses the excuse there is maintenance happening in the area, if that were true all 3 customers would have slow or no network, yet my mobile speed tests at 11.4mbps yet my ai cube broadband speed tests at 1.4mbps with zero devices connected, shameful and I can’t wait for the contracts to end il never use them again their customer service team are arrogant as well when you show them this evidence

    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.

    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.

    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.
