Since November the speeds went down dramatically. I can see Three mast in front of my window and speed im getting ranges from 0.3m/s to 11m/s its a joke...and sometimes it totally stop.
Ping goes up to 462.....common...21st century and 4G does way better than that. My advice avoid avoid avoid....if i could give i would give negative 10 stars!!!

A one star rating is actually too good. The service is appalling in every respect: speed, reliability, connection and customer service. After me reporting them to the ombudsman they even had the gal to deny that they deliver a well below par service. I’ll take them to court for breach of contract.

London Three Mobile  
Utter ****. In zone 2 central London, my closest mast is 100m away, and I cannot even get reliable 3G, let alone 5G, at peak times. Their customer service, the usual call centre drones, just repeat the same script over and over. Without doubt the worst service I have ever received from.any utility ever. DO NOT CHOOSE 3.

WORST INTERNET PROVIDER EVER!.Joined Dec 2019, got Huwaie B535 4G Home Broadband, was amazing for first 2 weeks downs of around 25 to 30 Mbps, then it all went wrong, now Im at 1Mbps and sometimes 4 or 5 mbs, most of the time does NOT work.
Ive complained over the phone so many times, cant pay my bills,impossible to stream any tv, cant even watch youtube,if it does load it buffers all the time,and the bits it does play is totally grainy and blurred.
My 02 mobile phone used as a wifi hot spot (tethering) gives 37mbps and all works fine when my tv links to that, once back on 3 nothing works.
I was their biggest hero in Dec 2019, now the biggest hater of 3, should of done more research, i called them tonight to say im cancelling and wont be paying them another penny,ive taken screenshots of speed (with times and dates on) videos of the speedtest etc, all as evidence, i even had to drive to my bank to physically put money in to pay upcoming direct debits, because i could not get online to transfer from one bank to another, total joke.
My mobile phone is faster then 3 home broadband, but my data is only 2gbs so used that up in no time, so if your reading this thinking of joining people, then don't, what i tell you is the 100% truth of my experience, as of March 3rd 2020, there are still massive outages in the UK, in most towns, Manchester, London, Hull, Bristol to name a few, its been like this for weeks,and for some months, impossible to come home from work and sit down and watch netflix,impossible,3 is absolutely the worst isp ive ever know,was amazing in Dec 2019, now its dire, ive given them chance to resolve this issue,ive reset the router 4 times, gone through all the settings with 3, nothings made it better, they have a massive outage and their network is a total joke, please believe me this is a true honest review, i thought maybe its because they are upgrading their network from 4g to 5g, no its not, they are even having to switch servers on and off just to try and give customers some service, i know this because my speedtest keeps showing different variants of 3s names,its is beyond a joke, if you are with 3 and are experiencing this, then cancel your direct debit, stop paying, send notification to their uk head office,and any evidence you have of the speeds service etc (screenshots/videos etc)they cant charge you for a service they are NOT providing basic english law, if they send you an invoice for the remainder of the contract then sue them for all your losses,and stress and grief caused from them NOT providing a reliable acceptable internet service, that what i am doing,its a joke at the end of the day when my mobile phone is much, much faster then their dedicated 4g system

HULL Three Mobile  
I can only say the same as others have, 'how I wish I had read more reveiws. The broadband service is diabolical at best, can not connect, slow unusable, then I found if you add a DNS server manually it does change things, it seems the router does not do what it is designed to do, I.E route, so, go online and search for free DNS, pick a couple of DNS ip addresses and go in to the IP address settings in your PC / Laptop/ Phone etc click manual DNS and add some DNS IP addresses, this speeds up the broadband connection on a pc. It worked for me.
The three mobile broadband service is awful though, nothing can fix that.

Oh, how I wish I had done more research and found this review page before I committed myself t a 24mth contract for Home 4G Broadband with Three. As with the high percentage of other reviews my experience of Three is abysmal. The broad band speed they advertised of 25 Mbps came in between 3-5 Mbps when I checked by my lap top. It’s like going back ten years with internet speed. The customer service as already mentioned by other reviews is terrible, you get sent to a call centre in the far east and get asked the same ridiculous question, which is very frustrating and you just end up going in circles. I eventually got them to admit that there was a problem and they admitted that there was too much demand in the area and that their system can’t cope. They have to their credit given me two months free of charge to compensate, and they admitted that the 5G upgrades they are doing to their system are causing the problems. It was clear to me that they know that there are problems on their system but just selling it to people anyhow. The other thing is that they don’t send you any record of your complaint and nothing is put on paper. I’ve been told that everything should be ok by the 26th march. I now have no internet in my flat, except one that it is so slow its infuriating and I can’t get another internet contract going because I’m locked into this one, it’s an atrocious service. If there are no improvement by then the only action I can take is to cancel by standing order, which in doing so I might face legal action. So, from my experience if anybody is contemplating to with Three, STAY WELL CLEAR OF THEM!!!

Edinburgh Three Mobile  
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.
