This is by far the worse company I have dealt with in 20 years their customer service is pathetic and was billed plus admin fees continuously despite cancelling my account Stay well clear as shockingly bad service and poor ethics of staff (who lie and don't do as they say and management alike.

basingstoke Three Mobile  
I use my 3 phone as my work phone on a day to day basis and run by own business. There has been very poor signal at my place of work for 8 weeks now, numerous client calls have cut out half way through and I have lost significant amounts of business. Despite 3 saying this will not be sorted for some time they are unwilling to allow me to terminate my contract without paying a huge early termination charge. In my view they have breached my contract by no longer providing a working network. I originally signed up with 3 because I was told they had good coverage in my work place, this is no longer the case and they will not let me leave. I have spent hours on the phone to them with no success.

London Three Mobile  
An absolute JOKE of a company!

Where do I start? The only reason I have to use this shower of fools is purely for work purposes.

I ring to top up the broadband and am ALWAYS in a queue. It's impossible to top up on line. They even have a dedicated line for the fact that you simply CAN'T ever top up on line thus incurring overinflated call charges!

You finally get to speak to someone who tries to keep you on line for even longer by trying to pass the time of day!!

After an age you are told that it's all been completed and to simply unplug and replug the dongle and hey presto!

NOOOO ! not the case - guess what? It does NOT get connected so you have to call back AGAIN and go through the whole procedure AGAIN.

I've got wise to this so today I'd gone through this whole frustrating sage and got put through to the 'technical dept' once AGAIN............

.............

Here we go...The 'tech' was telling me how to plug and unplug the dongle - yes been going that for an hour! Next he asks me to take out sim and do a few other stupid things. At this point I asked if I was on the Ant and Dec show. My sarcasm was wasted on him but never mind!

I didn't do any of the things he said but I pretended to. Guess what after another FIVE minutes of stupid instructions the internet came on!!!! I hadn't actually done anything!!!!!!!!!!!

He couldn't believe I'd DARED to not follow his instructions!! lol

They obviously get people to keep calling and waiting until they decide to simply connect you!

WHAT AN ABSOLUTE CON
AVOID THIS COMPANY LIKE THE PLAGUE!!!!!!!!!!!!!!!!!!!!!!

Lancashire Three Mobile  
Bought a new 24mth contract from THREE which came with a samsung mobile phone. Three months later the phone just became unusable, not least due to the garbage bloatware THREE preinstall, most of which I had uninstalled. It still left little imovable scabs, one was every time I touch the fone asking if I want to install THREE apps etc - Then the horror story really begins. THREE customer service just happened to mention fone warranty was ONE year, not the two years I signed up to. They also tried to get samsung to deal with the problem, giving me the runaround. I said my contract is with THREE YOU sort it out. Said they would send a new phone. never did. Made an official complaint and every step was blocked by them misusing the data protection act and claiming they cannot talk to me via email unless I give security details, despite the case already being open. So it was ok for me to send sensitive data but not for them. It then just became farcical and I gave up. They then advised I couldnt even complain to the ombudsman!!! A big fat lie. The network service itself was 2nd rate too. Many black spots and 3 and 4g unusable often. The company is a joke.

Lincs Three Mobile  
I have been with almost every phone provider and Three is by far the worst I had to cancel the contract within the colling off period. Three market an International sim so you can use calls, texts and data abroad. Nowhere on the website does it mention this actually only lasts for 2/3/4 (they still can't give a definite answer) until you are charged premium rates for using your phone abroad. I cancelled and have reported to ASA (Advertising Standards Authority) In addition to get my PAC code took my 10 days of constant calling (average hold time 45 minutes) to be put through to Mubai and to be told no comprende on most issues. A manager was due to call me back on 4 occasions during this time. They are so unhelpful. I really can't believe their service. Vodafone however text me my PAC code after leaving and their wait time is merely 5 minutes. I think i'l rejoin. DO NOT go with Three. They are an absolute Joke. also when you go into store they ask to scan your passport before giving you a sim card. I find this highly unnecessary (I mean it's not US border control And since three recently suffered a hack I think its a consumers right to be more careful as to where their unnecessary details are held.

Manchester Three Mobile  
I've been a Three mobile customer for 4 years and for 3 years I used to have unlimited data, this year I went to the shop and the guy told me to change it for 17 G instead keeping the unlimited contract. That's fine! It's cheaper and my average is 12G per month. However since there it becames a nightmare!!! EXTREMELY SLOW internet, internet goes out all the time... so annoying! Another thing on the day that i changed my contract they told me buy this and that and we will give you a £150 voucher for amazon. I was happy with that. £150 voucher who does't like it?? however when i checked it online they say the voucher will be redeemed after first payment (no problem) and then amazon could take 2 to 3 month to send the voucher...this was in August 2016 5 months passed and nothing!!! I wrote a complain to three and they ignored me!!! Very disappointed!!! I pay every month £55 for an useless service!!!!! Can't wait for next August to finish my contract.

Wembley Three Mobile  
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.

Newport Three Mobile  
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.

National Average Speeds March 2016

Average mobile broadband speeds rising in 2016 while fixed line home broadband speeds coast at late 2015 levels

Posted on 2016-04-08 16:59 in Announcements News 4GEE EE Hyperoptic Vodafone Three Sky Virgin Media BT Post Office

Each month hundreds of thousands of broadband customers test their speeds with our broadband speed test. Since the end of 2015 there's been little change in average speeds from home broadband with average download speeds for March 2016 coming in at 20.41Mb and average upload speeds at 3.73Mb.

However, our test also supports users testing on tablets and smartphones, meaning we can report on mobile broadband speeds from 4G and 3G networks. While home broadband has been stable, mobile broadband average download speed has risen by a full 2Mb since December and upload speed by 1.6Mb, the average mobile broadband speeds for March 2016 were 15.31Mb download and 3.71Mb upload.

When the big mobile broadband and home broadband providers' average speeds compete on the same table, it's only Virgin Media's DOCSIS 3 cable broadband that outperforms mobile broadband, clocking in 46.95Mb, with upload speeds at 5.9Mb. 4GEE is ahead of BT Broadband with download speeds clocking in at 18.71Mb, faster than BT by 1.07Mb. 4GEE and Vodafone mobile broadband sit in overall 2nd and 4th places beating all home big broadband providers' averages bar Virgin Media, with Vodafone's 16.26Mb average mobile download speed only 1.38Mb behind BT.

Of the home broadband providers Post Office Broadband still has the UK's slowest broadband speed overall with only 4.38Mb average downloads and 1.67Mb average uploads, well below the average speeds expected for copper phoneline broadband. Three tested with the slowest mobile broadband at 12.09Mb downloads, but this still beat home broadband offerings from Sky and EE.

When the supplementary broadband providers table (see page 4 of the report) is included we can see that fibre to the building provider Hyperoptic tested as the fastest broadband overall with 91.7Mb average downloads and 77.3Mb uploads.

National Average Speeds December 2015

Average fixed line download speeds remain stable over December 2015, average mobile broadband speeds see minor increase

Posted on 2016-01-08 12:21 in Announcements News 4GEE Hyperoptic Vodafone TalkTalk Three O2 Virgin Media BT Post Office Plusnet

December 2015 saw average download speeds for fixed line providers recorded by users of our broadband speed test remain stable in comparison to the results from November, coming in at 20.56Mb. Average upload speeds saw a 0.15Mb drop to 3.68Mb.

Of the big 5 home broadband providers, Virgin Media remained in first place but their average download speeds appear to have levelled out since rolling out their 200Mb service, remaining stable at 46.57Mb, with upload speeds at 5.66Mb. BT Broadband retain second place with average download and upload speeds steady at 17.58Mb and 4.42Mb respectively. TalkTalk move up to third place, with download speeds stable at 12.8Mb and upload speeds dropping by 0.21Mb to 1.86Mb. Plusnet drop into fourth place, dropping by 0.59Mb to 12.6Mb for average download speeds with a 0.39Mb decrease to 2.85Mb for average upload speeds. Finally, Sky remain in fifth place with a 1.1Mb fall in download speeds to 10.92Mb, while their upload speeds decreased by 0.41Mb to 2.47Mb.

Results from users testing with mobile-enabled devices including phones and tablets suggests that mobile broadband speeds saw an overall rise since November. Taking mobile broadband separately from home broadband, EE Mobile retain first place, with download speeds increasing by 1.1Mb to 17.55Mb and upload speeds holding at 3.87Mb. Vodafone are in second place, seeing download speeds fall slightly by 0.19Mb to 13.76Mb and upload speeds steady at 2.82Mb. O2 are in third place with download speeds at 11.78Mb - a respectable 1.4Mb increase over last month - and upload speeds at 2.53Mb. Three are still in fourth place, with average download speeds of 9.84Mb and upload speeds of 2.56Mb.

When mobile broadband and home broadband average speeds compete on the same table, 4GEE is head-to-head with BT's second place with a difference of only 0.03Mb. 4GEE and Vodafone mobile broadband sit in overall 3rd and 4th places beating all home broadband providers' averages bar Virgin Media and BT. This suggests that 4G broadband may have higher uptake levels relative to 3G compared to uptake of the fastest possible fibre broadband products relative to cheaper options.

This month's supplementary broadband providers table (see page 4 of the report) found Post Office Broadband had the UK's slowest broadband speed overall with only 2.55Mb average downloads and only 0.33Mb average uploads. Hyperoptic was fastest overall with 102.1Mb average downloads and 92.13Mb uploads.

Three Mobile Buyers Guide

Can I get Three mobile broadband?

Unlike other mobile networks, Three doesn't have any 2G GPRS or EDGE data service, so you'll only be able to access Three mobile broadband in areas with 3G or better coverage.

If you're in rural or remote areas and using a mobile phone handset, you may be able to roam onto Orange's network, but this is only in selected areas and only provides calls and texts, not access to Internet data. However Three have one of the country's largest 3G networks with other 97% coverage, so it's rare for towns and cities, and many major transport links, to have no 3G coverage.

Three offer a coverage checker that allows you to test any UK postcode for coverage on Three's 3G, Advanced 3G or (from 2014) 4G network, with colour coding showing which areas have strong coverage indoors, and which will only get good signal outside buildings.

Advanced 3G

Three cover 80% of the UK population with their Advanced 3G service, which uses dual channel 3G to provide double the speed of a 3G mobile broadband connection.

In order to enjoy Advanced 3G you must choose a premium Three dongle or MiFi personal hotspot, or own an existing device with DC-HSDPA support.

Get ready for 4G at no extra cost

All of Three's plans plans include 4G speeds at no extra cost. This is in stark contrast to other mobile broadband providers who require you to pay extra for a 4G or 4G-ready tariff.

However, you must own a 4G/LTE capable device in order to enjoy the 4G speeds your tariff will include after Three's roll out. Depending what tariff and contract length you choose, 4G-ready devices can be more expensive than Three's standard dongles and MiFis, which only support 3G or Advanced 3G.

Largest 3G usage allowances

Three offer a 15GB usage allowance on some deals making their Advanced 3G service a viable alternative to a fixed line home broadband package for moderate users.

There's no separate line rental for mobile broadband so when making like-for-like comparisons with fixed line broadband remember to add the £10 to £16 line rental changes to the fixed line figures before comparing with mobile prices.

If you don't use your landline for calls and you get good quality Advanced 3G connection from Three, switching to Three mobile broadband could free you from the need to pay for a landline.

Things to watch out for

As Three have a requirement that their hardware be 'new and unused' in order to qualify for the 14 day returns period, it's more important than usual to be sure before committing to a long contract.

Be careful to check all the postcodes where you're likely to use your mobile broadband to ensure there's good coverage. Especially make sure that places where you'll be inside a building have strong indoor coverage. If you're planning to use Three as your main broadband connection for the home, make sure that you have strong indoor Advanced 3G coverage - standard 3G speed can be surprisingly slow in built up areas at peak times as it depends on how many other people are using the service at the same time.

Be sure to check that your monthly usage is less than the amount you're planning to sign up for. This is especially important if you're on Three's largest allowance of 15GB as there'll be no higher option to upgrade to should you find you use more. If you go over your monthly usage allowance, you'll be charged 10.2p per megabyte (more than £100 per gigabyte), which can very quickly add up - however Three should inform you before you exceed your allowance.
