    Never have I experienced such appalling customer service, misinformation and zero value for loyal customers. As a whole Three is one of the worst broadband networks out there. They overcharge extensively even though they reassure you the data usage is capped and do not notify when this changes. Resulting in paying hundreds of pounds extra from what you expected to pay. Putting customers at a loss at their gain. If you're thinking of joining 3 and do in the future incure a problem please expect: long telephone calls, repeating yourself to multiple call handlers, with the end result being a waste of your time and money. Completely unprofessional.

    Hi, I seriously question any negative "reviews" of three mobile.I've found them brilliant for customer service. You always get through to a real person. Someone who is normal, personabke and really at ease with any query you have. I've just got their broadband unit. It's great.It works. That's all I ask. Granted I live in Central London but hey: that's the advantage of cities over a village! Compared to VirginMedia which is constantly suffering from digging up the riad or your front drive 3mobille is a dream.

    I have been a Three Mobile customer for quite a few years now. I have managed to develop 5 websites on a Three Mobile dongle so I can't really complain about the usage, but I will say that the Customer Support is certainly challenging.
    We have had an issue with the dongle recently so we needed to get in touch with Three. We went to their support page many times and left messages as suggested, but we never heard from them. It may seem a bit strange, but the customer support on Twitter is excellent. Unfortunately it is limited, because they then transfer you to the Three support page where nobody gets in touch. However, if you call customer support they will try hard to sell you another contract. Be careful. A few years ago, I agreed to a 12 month contract and they put me on a 24 month contract. As I was a loyal customer at the time, I accepted it because I fixed the problem I had then myself. Unfortunately, customer service recently has been shocking.
    We try not to call customer service if we can help it because we are unable to understand the people on the other end of the phone.
    Many years ago, I did ask to speak to a Manager or Managing Director, who was very kind and was very helpful, but to be honest it should never get to that stage in the first place!
    As I use the internet alot, for business, I am now looking for another service provider with excellent support. I doubt I will find anyone who can match the deal I have which was made with the Managing Director, but I guess customer service has now become my top priority.

    I went into the Three store in Lewisham. Arrogant staff who were not very helpful and did not provide good information.

    First day I have finally got the router and finally managed to get it activated useless instructions provided by the staff at three store and with in the product its self. I had to find a way to contact customer service and talk to a human and not get thrown around the houses to speak to the right person. Waste of time.

    Router is now finally working, signal is rubbish even though it says my area should have a super strong signal.

    I go on to the website to check coverage and I get this message: "We're really sorry. There's an issue with the network in your area at the moment.
    We know that there's a problem with the service in your area and we're working on getting it fixed. Check back within 7 days for an update."

    WHAT!? Not a good look, I've never been with Three before and was trying to look for an alternative to a crappy internet service currently provided by Sky over land line.

    Thankfully I ordered online and have a 14 day returns period. Something to take note of if you order in store is that you don't get the 14 day return option so make sure you order online if you are going to try their home broadband so if it's rubbish like mine you can return. Will still trial it for the next 14 days and update if anything different from the above otherwise I will be returning everything.

    Overall so far, waste of time and effort, not happy...

    I don't get any service from three since I don't have any signal on my phone. Can't make any calls, can't text, can't use data either. Just have red no signal thing all the time. Have now idea what I am paying for! Tried to go to a local three store- useless. Report network issues almost daily- never heard anything back from them! Not sure how they legally exist for taking money and not providing any services. What a scheme! Three Sucks!!!

    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.

    They promised it would cover my area. It did no. Despite requests it still did not cover. Breach of contract. Returned mobile phone and cancelled contract. These nasty people called in the debt collectors and threatened legal action. Called their bluff and eventually they gave up. Nasty vindictive people that do not do what they say. Poor coverage even poorer customer service. Avoid like the plague.

    I have an “All you can eat Unlimited data” contract with Three. Everything was going fantastic for a few months. My downloads and my streaming speed was great and so was my Internet speed.
    About 3 months ago I noticed that my signal wasn’t so good anymore and that the speed of my downloads was really bad.
    Don’t waste your time calling them because they’ll try to make you think that your SIM card is faulty or that your handset is faulty or any other thing they can distract you with to avoid to tell you that they are throttling/restricting your downloads.
    When I connect to the WiFi everything works wonderful, so my SIM and my Handset cannot be faulty.
    I called them and asked them if they were restricting my downloads and they assured me 10 times that they weren’t do anything like that, that they don’t restrict anything. So I asked them to send me an email confirming the statement they just made 10 times and they were so certain of. The answer to this of course was that they don’t send emails and that I can find that information in their website. So I asked them to direct me exactly to where in their website they mention this piece if information. After being reluctant to that and then made me wait for 15 more minutes on the line, they told me that they do have restrictions but just in peak hours. They have just lied to me, repeatedly. I was so furious that they treat the costumers like we are stupid. I used to have a service I don’t have any more. A service I’m paying for and you are supposed to provide.
    So now, I asked them to direct me exactly to where you can find that information in their website and what I could read in this link is that they restrict Internet from 3pm to 12am. You can read more in the link below.
    The question is, what is the point of that? That is exactly the hours anybody will be awake to do anything. They make it sound as if you can just set your alarm for 2am so you can wake up and watch some TV.
    They apply these fair use policies during exactly the hours people actually need access to data. What’s the point of paying for it then? Or having it all? It’s not like you’d be awake when speeds are normal.
    It’s now 12am and my download and streaming speed is poor. I experienced the same thing with Giffgaff, to the point you couldn’t even use your browser or listening to the Internet Radio. Three is just going to get worse and worse. If I were you, I wouldn’t join them. You’ll get into an endless loop of frustration and find yourself talking on the phone to people who’ll make your life so difficult that you’ll feel physically sick.
    I’m now looking for another mobile company – I can’t deal with this poor service again.

    Unethical Standards of CEO & Executives of Three

    I'm on the sim rolling monthly One Plan of Three network. I signed up in winter 2013. I was assured it was for an indefinite period, with no end date and for as long as I wanted. I signed the monthly plan of £18 unlimited data, unlimited tethering, 2000 mins, hundreds of texts.

    On 5th Nov 2014, I received a text from Three network, "Hello. We need to speak to you about changes to your plan. Please contact us free on 08003583429 to speak to our dedicated team." I spent almost 45 mins trying to get through to Three to ask what was going on? They evidently were besieged by other callers wanting to ask the same. All I got was bubblegum pop music, so I went to a Three store in London's West End. The store manager revealed that on Fri 31st Oct, 2014 news came down from on high - the CEO Dave Dyson and executives - that those of us who'd signed up for the unlimited data and unlimited tethering under the One Plan should be instructed that our Plan was no longer available to us - even though we'd signed for an indefinite and unlimited period. The rug was to be pulled from underneath us - whether we liked it or not. We were now to be charged more and be given less. If we didn't like it, we would be told to go elsewhere and our account would be terminated. We were not to be given a choice. The store manager also said that the CEO and executives knew this would result in numerous disgruntled customers and complaints, but he said "they don't care". He said he'd received many complaints from customers who'd received the same text as me, and was advising us all to complain to Three (he warned it'd make little difference as the instruction, to treat One Plan customers so abysmally, had come from the top of Three) and to also register complaints with Ofcom. He was very apologetic and said it was unethical and a blatant dishonouring of an agreement we'd all signed in good faith. He also said that it reflected very badly on him and his staff who'd acted in good faith when convincing me and others to leave our other networks/deals, and to move to Three's One Plan. The nearby customers all heard him speak openly and with no respect for Three's unethical treatment of customers.

    I got a 300 minutes + 3000 texts + 12GB data to which cost me GBP20.

    My problem are :
    1. There are too much slower of data connection
    2. There are too ofter 'disconnect' issue during surfing online
    3. There are too much often 'NO SERVICE'.

    It's not good to complaint, besides its not type of people who like to do so but all I can say here is.. I made a mistake when I thought that UK has its all the most highly quality both of services and performance. It's so embarrassing when I realise that is just wast't true at all

    This is would be the first, and the last I'd use this ISP.
    The most worst ISP that I would not recommended it to other service user.

    I am so disappointed in three and it's only been 1 day. I tried to upgrade my husband's account to change the plan and pay for a new phone as well.
    They said it was impossible and I had to start a new contract for 41.00 for 2 years to get the phone I wanted for my husband. Samsung Galaxy S7 Edge for his bday. They did a credit check and approved a 2 year contract with 14 days cooling off period.

    The signal service has been so poor that I called to complain and was told to upgrade to a 4G phone and plan for free, and I could cancel the other contract.

    They said they had to run another credit check. I complained that they only did one 12 hours ago but they insisted they had to do it again.

    Yesterday was glowing I was told and today I did not meet criteria. No leisure vessel in my driveway since last night so very upset.

    Yesterday I was told there was a popup saying my cretit was exception and they offered me a free tablet with a data contract for 9.00 a month.

    Today, after 3 hours on the phone and 4 people I feel angry, screwed and bitter.

    They have damaged my credit for no reason and lied to me about my options.

    Literally we have 2 bars by the south facing window and 0 in any other room.

    The worst network in the UK and their customer service is waste of time as they made me stay on call for 30 minutes; transfered from one department to another as I'm trying to get PAC Code to transfer my number over to another network but they told me to call back tomorrow so they would give me PAC code, apparently generating this code is rocket science according to three.
