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.
London Three Mobile  
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.

london Three Mobile  
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.

Leeds Three Mobile  
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.

london Three Mobile  
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!!!

Southport England Three Mobile  
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.

Hove Three Mobile  
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
