    Unbelievably terrible experience, do not use 3 for their home broadband.
    Early into our contract the wifi was awful - fluctuating all over the place and unusable half the time. We called support and were told that we had to call while the wifi was actively down and this had to be a problem three days in a row for them to do anything about it. As it's wireless wifi, they specifically don't guarantee any minimum speeds, so you actually have to be fully offline to my understanding.

    Now that our contract is up, we called to cancel it, only to find out that our wifi hub is outdated and has been known to be faulty for a long time now (Huawei B311). Never mind the half hour of flat out refusal to cancel the contract while trying to negotiate for us to stay on. It's beyond me that they weren't recalled and we weren't notified at all.

    I used their webchat service to attempt to register a complaint about the fact that they were continuing to knowingly provide a faulty service and that we'd generally had terrible service for the duration of the contract, for service for future customers.

    I was told it was our fault, then threatened that they would waive the contractual 30 day notice period, leaving us without wifi completely until the new provider sets up in a couple of weeks.

    Seriously, just don't even bother. I'm completely floored by the whole experience.

    My 4g Broadband from 3 is all but useless. A complete waste of money. It used to work but for the last 6 months it is 1mb down download/ less than 1mb upload and it periodically just drops out . At the moment I just use my phone as a mobile hotspot. Waste of money.

    its a pity i have to give 1 star because they dont deserve it.I have to log in every 5 minutes so its impossible to do anything.I contact customer service who blame everything they can think of weather.location.congestion ect but what it boils down to is they charge for something they dont provide..Absolutely useless,dishonest company..do not waste your money.

    it works well at the first one month, but one day, they suddenly blocked me getting into some public websites,which i used all the time. i have to call them to unblock me and now the speed is terrible and unstable, i can't even use it for my work zoom meeting. and the funny thing is I can't even log into my router, Three is obviously monitoring people, very doggy!!

    I have full signal on my router but my speeds is about 1 mbs , most of the time it’s lower than that , I’ve seen speeds of 10kbs which is rediculas ... I’m stuck with this contract for another year! It also just cuts you off the internet for no reason it just stops !!! I was told it would be perfect for Xbox live , this was a massive lie , you cannot compete with someone with real internet because you are lagging so badly!!!!!!!!!!!!!!! It even struggles to run Netflix! NOT HAPPY!!!

    I went to the 3 store to ask about their mobile internet. While I was there I was told about the 4g homefi, 300mbs and only £22 a month wow! I signed up and cancelled my sky contract. The best speed was just over 15 meg at 5 AM. Before 10 am I could get 4 to 5.5 meg after that 1 meg was fast weekends we often couldn't even get on Facebook. My first complaint I was told it was because of the unlimited service and they are working hard to solve the problems. My second contact when I asked to cancel my contract was agreed without any argument. If you are considering 3 4g homefi I would suggest you ask them to put the download speed for your postcode in writing.

    Very rarely does the speed reach 20 megabits. It never does in the evening and often stops working completely. The wifi unit itself also crashes often needing to be reset in order to get any connection. I have been with three many years but this service has let them down terribly

    As is often said in these sites. If there was lower than one I would give it. Appalling service, appalling speeds, total lack of interest if youcontact the shop. All in all, I am suprised they are still in business. Just absolute *****. And I NEVER normally bother with giving reviews. So that's how bad it is.

    I have expected much more from a company such as Three.

    The Three guy at the Chester shop said I should get "tier 1" reception and I should not believe the negative reviews. He was wrong on both accounts.
    The TV that needs only 3mps gives me distorted picture. Even the simple internet browsing takes a long time.

    My advice is only to use them if there are no other options.
    I will be disconnecting the service the minute my cable service is connected.
