Plymouth Three Mobile  
Practically useless.
Intermittent connection that rarely exceeds 0.1mbps between 6am and midnight.
Customer service is so bad, I could only call it hostile.
I consider Threes sale of the package to be entirely fraudulent.

NI Three Mobile  
Very poor srvice works sometime then nothing for hrs. would not waste time or money using 3 mobile broadband. Support is a waste of time they just blame number of people using it. HELLOI thought thats what people pay Broadband for to use not look at. You spend hrs on hold on the phone and get no where with them.

Eye suffolk Three Mobile  
absolutely horrific customer service! I've been having issues with my mobile broadband and Three simply refuses to take responsibility for it and they want to charge me loads of money to cancel the contract. I'm now making a complaint to the Communication Ombudsman Service.

London Three Mobile  
If I could give no stars I would! Shocking speeds and even worse customer service.

I live in Sheffield city centre and don’t have access to fibre broadband, so the fastest speed any provider can guarantee is 6 mbps which is fairly slow. I saw that Three were claiming much faster speeds so decided to give it a go! Oh how I wish I’d read the reviews beforehand..

It worked straight away out of the box which is about the only good thing. The speed fluctuated between fairly quick and unusably slow almost every 5 minutes. Tried the router all over the house to no avail. After a while, it settled on about 0.7 mbps which it never really changed from, despite showing full signal and 4G.

I purchased this in the Three store which doesn’t offer the same returns guarantee as online, however the store manager agreed to honour the 30 days and authorised it in my contract in case I changed my mind, and with lockdown looming (and closed shops) I was told I would be able to cancel on the phone.

This is where it gets even worse.. after being pinged around from pillar to post between various departments, I was told on the phone that they can’t authorise returns on the phone for products bought in store, and only the technical team would be able to do this based on the dreadful speed. After finally getting through to the technical team, they said I would only even be considered for a refund once they had conducted a weeklong troubleshooting investigation, and if the outcome of that was that they didn’t agree with my issues, there would be no refund. Feeling untold levels of dispair and betrayal about having been lied to in order to get me signed up in the shop (which had now closed because of lockdown), I opened a complaint in the online chat. After royally kicking off, the agent managed to honour my cancellation despite making a big song and dance about how it was outside of process and they were only making the exception as a goodwill gesture.

Moral of the story.. DON’T BE SUCKED IN BY THE PROPOSED SPEEDS! Like most of these reviewers’ experiences, mine was dreadful. The customer service is abysmal too.

Bokton Three Mobile  
Three when it works is great... just its not very often these days.

For multiple years I have had long periods where text messages don't arrive... they just disappear, even when the sender is standing right next to me. Ive complained about this multiple times both to tech support and in shops, and am fobbed off with its "phone settings"... four different phones, two different operating systems... come on... three buggered up the white pages entry when my number was ported to three a decade back, and its been broken ever since.

Worse, right now I am working from hme, using three mobile as my only way to contact office and data, and constantly see reports saying that three are upgrading my data connection and to expect faster speeds... but this is not the case. while "working" on the network I see data speeds slower than when I was using a dialup modem in the early 90's, and in the evenings it gets slower each week.

I am fed up with being fobbed off by callcentre chimps, and even getting through to the second line tech support fairs no better. I spent 10 years lecturing in RF and digital communications technology. The last thing I need is yet another idiot insisting I perform a factory reset. I shall be leaving three.

Shrewsbury Three Mobile  
I would give zero stars if I could - they are, in my view, dishonest, unreliable and put so much pressure on me - a vulnerable pensioner I wanted to end my life. They put me in hospital with suspected heart attach as there is no let up from them. They lie in writing saying they need your passport and driving licence to look at your complaint as this is their data protection policy but will not send you a copy of this alleged policy. They tried to charge me £200+ because they sent me two router instead of one (I live in a terraced not Buck palace) idiots. I rang them and emailed the day these 2 routers arrived and asked for an SAE - to return one - I just got a bill for over £200 which I refuse to pay. Ireturned the extra router. As I do not have a passport or driving licence they will not deal with my compaint. I wrote to the CEO by letter twice and sent him an email - he did not reply either - so from the top down - untrustworthy and dishonest. They send me a buill for £48 (my contrat is £22 pm) and will not tell me what it is for but said they would just adjust my direct debit and take the money out of my account - thieves. I stopped the dd. I wait for someone with a brain cell to respond.

W MIDLANDS Three Mobile  
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.

London Three Mobile  
Was once okay, but for the last few months speeds are terrible. Cant play on xbox until after 10pm, or before 9am, during daytime it wont even sign in. During the day, with dial up speeds on laptop just looking at ebay etc. They have oversold capacity, and are now throttling . Just downloaded a 40gb game, it manages about 6gb a night so it only took around 8 days. I will not be renewing contract.

Chapeltown Leeds Three Mobile  
I have had 3 broadband for 14 months now. When it works speed is ok but often get buffering. In the last 3 months there have been 3 significant service failures lasting several days. The last failure ended today after 9 (nine) days of unusable internet. Current speed is half what it was 2 weeks ago.
Three customer support help desk are hopeless except at giving endless apologies but no action. You can tell buy their tone that they don’t give a damn and are just following a script.

I have currently raised a formal complaint. Three are wanting to stall this and are declining to respond formally. I intend to end my contract whatever and revert to land fibre.

I could not recommend this network to anyone unless you have no other options.

I have been signed to a plan to which I did not agreed far higher that the one I wanted they have no sent any proof of my commitment to this higher plan, and now I will be rip off for a year!
Lopez Three Mobile  
We’ve had this‘service’ for just over a year now. We signed up in desperation as our BT cabinet is still not fibre enabled and the ADSL connection was awful.
It’s never been blazing fast, my jaw drops when people claim 200mbps. The last month it has just stopped providing any sort of service at all.
Customer service just talk me through a hard reboot of the router which achieves nothing.
Avoid like tile the plague.

Abingdon Three Mobile  
I know a lot of people are down on 3, but it really has felt like they were putting in some serious infrastructure round here. I'm in an 'outside' reception area, on the fringe of coverage, so I got an external aerial for my 5G hub. It was pretty good at the beginning (4 months ago), averaging 200Mbps, but it broke every couple of weeks. Now things are better: seems steady, and am routinely getting 500Mbps at my computer. That's 4 times faster than most fibre. And it doesn't go slower in the evenings. Am quite impressed: for 29 quid a month it's impressive. I hope it stays like this! Well done three...

hackney Three Mobile  
These guys have been quietly taking money from my account for a service which they cannot actually provide. I had this router from when it was Relish. I thought that it was cancelled but I was wrong. Now when I tried to reconnect last week I was eventually told that there was no 4G available in my area. Then they tried to sign me up to 5G and wanted my card details etc. I checked on their site and found that there is no 4G or 5G mast in my location and would I like to be contacted when it eventually comes around! I have cancelled the direct debit myself and immediately go an email saying that I had not replied to previous emails about the Direct Debit cancellation?? These guys are liars and thieves.They even have the front to complain when you stop them from stealing your money!!!!

Waste of money at best we are running 1.77 mbps download speed. Rang to complain after 1 month of start of contract when the cancellation period was over as that's when it went garbage. Been calling at least once a month so for nearly 18 month and they only have records for last 4 month said I have never complained before. Then to be told the coverage in my area is very poor but in the shop when we took the contract out they stated it runs near on perfect. Absolute ******** will not renew, robbing tears.

Doncatser Three Mobile  
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.

Southampton Three Mobile  
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

Scotland Three Mobile  
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.

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.

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.

Pretty much is realist here what others have truly said in their reviews... Awful, very slow connection (on SIM only) everything slowed down. Previous provider EE. I had no problems. Customer service abysmal. Left me waiting an hour twenty minutes, then, as others have said, they ended the call... Don't do it. Cheap but not worth it...

Liverpool Three Mobile  
Its been a frustrating and ultimately unsatisfactory relationship with 3. I've just now cancelled my broadband after many months of poor connectivity and customer service, worse than other companies I deal with that are also working form home during Lockdown.
How does an existing customer, since 2011, feel when you find out your provider offers an unlimited broadband for about half the price of my current contract? That they finally admit your router is old and will send you a new one after many previous calls where excuses were made, e.g. work in your area, reboot your device, reset it etc. etc. Too many excuses, not enough interest in resolving the issue until I finally rang in to cancel. Too difficult to make a complaint (no complaints email address!)
