    Worked fine in the beginning (first month - February 2020) after which they started upgrading the network, this meaning 2 days a week the network would be down completely and when was working I had 2-3 mb speed. November 2020 network is up and running properly upgraded to 5G with speeds than can reach sometimes 5 mb. 2 more months and I will close all 3 contracts with 3.

    Oh dear, I have the same tale of woe that everyone else is posting. When I first switched to three mobile broadband last year it was good enough - getting ~7mbps. But now the service has dropped to the point that web pages won’t load and the servers can’t be contacted. Right now I have 0.4 mbps. A lot of the day it is totally non-functioning. But I have full signal strength. So clearly it is a throttling issue that 3 are doing. They have oversold their capacity until no one gets any. I have tried complaining but it is a futile waste of many hours and nothing is resolved. Why is it so difficult to complain to them? - and why don’t they take the complaints seriously? I have many neighbours who are in the same situation – all wishing they were not with 3 – so it is not just my equipment. Earlier this year I complained and they reset something on the network, and suddenly service was resumed. (removed the throttling?). But it had all dwindled to nothing. Full signal strength and no delivery sums them up. And they don't want to know.

    The worst Internet service ever!!!!!! Everything everyone else says on here is absolutely true. The only positive thing I can say is some times, weekdays, upto 18:00 I can watch Netflix for a few hours, bbc, itv 4od buffer all the time and My5 don't even bother. After 18:00 and weekends it stops all the time, have to keep resetting it. I have been without any service for hours at a time. Like now for instance. Customer service lie, in fact fight back!! I would bet staff at Three don't have or use it. I have 3 phone, now just sim contract after years of huge bills, I use it as a hot spot, in the same home as my broadband and get a better service (tho that also buffers like crazy) DON'T BOTHER WITH 3 BROADBAND, PLEASE BELIEVE THESE REVIEWS

    Without a shadow of a doubt AVOID 3. Aside from their absolutely abysmal connection speeds, they claimed they hadn't received the package with the contents of the broadband router when I tried to cancel. When I phoned their foreign, outsourced and rubbish 'contact us' number that they supplied on their fictitious bill, they told me they would investigate my claim and get back to me, instead of this they just moved it on to a debt collection agency (i presume as a scare tactic). Awful Awful company from start to finish.

    Although three are undoubtedly cheap, their customer service is just a total joke so I have left them.

    I was formerly with Relish who provided 4G home broadband in London. Customer service and broadband was slick, efficient and helpful. Three bought relish and customer service turned to an absolute joke.

    This year, they contact me to terminate my contract early (without my consent) as my contract with three was being moved to the wider three group (yes, it didn't make much sense to me either) so they were terminating my contract early and offering me the same service for more money. How kind of them.

    I agreed to stay, but the experience has been so bad I've cancelled after the first 3 days. Even trying to stay was painful - I was asked to contact them which I did so and was told I would receive a call back 2 weeks later. That call back never came.

    Eventually the new service started but speeds dropped from 140mbps (5G) to 10mbps over night. I spent a couple of hours trying to reach customer service to find out why but couldn't get through to a human. Eventually I decided to cancel as the service was so bad. I say I've cancelled, but in fact I very much doubt my contract has been successfully cancelled. After 4 hours on the phone and webchats trying to cancel the contract, I still don't think they've done it properly - I rang back to check and they had already messed up the cancellation. I have had no email confirming the cancellation and have written two letters as a result. I fully expect to be billed for my first month, or more likely to receive a threatening letter as I already cancelled my direct debit to them.

    If you want your broadband provider to be as hard work as this in order to save a few pounds, three are the company for you. If not I would avoid them like the absolute plague. I have probably wasted 10 hours on the phoen and chats over the last few weeks trying to ask basic questions or make basic changes which should take minutes, and I still don't think they've got it right.

    There's nothing wrong with the advisors. The systems are just set up completely wrong so you get put through to the wrong person who then transfers you and more often that not you are cut off in the process. Then when you do get through to the second person they also tell you they are the wrong department. This happened several times until I just couldn't bear it any longer.

    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.
