Lamborghini and Maserati don't need to advertise their products because their state of art quality screams for itself, mouth to mouth.

Unlike terrible service quality by 3 that needs to drop their prices to pathetic levels AND sponsor Chelsea to desperately attract customers.

Here is the horror story, on Sunday I walked in the store to get my SIM card checked for not working since I hadn't topped it up for over a year as I was abroad doing business and being their customer for 4+ years, I was expecting that I wouldn't need any identification to confirm that im their client.

However, I was sent back home to get an ID. I went back to the store then I was told that they can't accept my EU ID since DOB and pic are not on the same side. I wasnt even told beforehand so I had to go another round to get my passport.

After spending 2 hours in store, observing the employees STRUGGLING to get their customer support service colleague on the phone to sort my issue out, I was told to come back on Monday and try again.

On Monday, still the same STRUGGLING story, so they decided to go Live Chat, which is something I coud do myself at home and save myself time of my life and money.

Eventually after 30 minutes I was told that my SIM would be delivered to my address in 1-2 working days.

However after 3 working days nothing shows up, I go Live Chat and to my huuuuge disappointment, I was told that my SIM hadnt been placed in delivery by mail yet.

Causing me to lose even more money because people were unable to contact me.

Beyonf awful, I would rate 3 with ZERO stars if I could.

Birmingham Three Mobile  
Customer service is terrible, as soon as my dongle broke, they did not want to know, tried to cancel as I was out of contract, sent many letters, chats, all were not replied too, They referred me to a debt agency and it will soon be in the hands of the Ombudsman.

Haverfordwest Three Mobile  
Don't sign up for broadband with this company. like other sunscribers the first 4 weeks was good. After 4 weeks the speed is between 2mbps and 12mbp and constantly drops signal. The router is useless, 4G poor, 3G bit better but poor speeds. As for 5G ready they can't get 4G ready. Customer service is basically non-existant. I'll give them another month. If they can't provide the service they advertised they wont be getting my money. I've seen other posts on here where people still pay for a bad service, if we all refused to pay they would soon buck their act up.

New Basford, Nottingham Three Mobile  
Very slow, signed up for a Three mobile, first month or so I was getting 30mb then it has steadily decreased. I even bought an external antenna for a new router to try and improve reception. At best on an occasional time we can get 17mb now, but usually is around 7 - 9mb with 3mb upload. A computer guy I know said that Three will be just throttling my bandwidth and slowing my speed down. My external antenna faces a mobile tower in direct line of sight, but because Three 'piggy back' off the tower rather than own it, they get limited bandwidth on it as well so all in all it's crock of sh*te.

I will change to another supplier when the contract ends but I think the UK as a whole just does not have a good enough internet infrastructure for a modern economy.

South Ayrshire Three Mobile  
We took up a contract in March as we had just moved into a new apartment and they assured us that the contract could be cancelled whenever and we would only be charged for data used.
2 weeks after taking up the contract (April 2020) we tried to cancel as we now had a better deal (better service and price) and they said we could not cancel due to COVID and to wait until they reopened their cancellation service and we would be refunded due to the wait as we were no longer using this service.
Now in June, we tried 3 times to cancel and we've had various excuses (computer system is down/not able to cancel atm), I finally got through today via telephone and was not able to understand the person on the other line (terrible signal on their end which is ironic) and have been informed that there will be no refund and that they are going to take another £30 next month prior to cancelling!!
Avoid this company at all costs!!!!

Horsham Three Mobile  
The first few weeks of mobile broadband via Huawei router were good - high speeds, low latency. Convienently, after the 14 day cancellation period had expired the connection nose dived and hasn't been the same since. I can't even explain why this is bad, it's just inonsistent. For example, once I am actually onto Youtube or Netflix or whatever and I'm streaming then it's fine, but loading the basic website or google etc takes so long - I'm talking 5-10 minutes just to load google search results. Again, convienently, when I do a speed test it gives good results! But this doesn't actually translate to the usability of the connection.

Wasted hours on the phone and on chat getting consistently passed from pillar to post. They won't cancel my contract and want over £300 for the pleasure, they're a total joke, I can't even return the huawei cube thing as all the shops are closed, had to cancel DD
I could go on for hours but they've already drained my will to complain
Don't get involved in this nightmare, Think I'll try watchdog
0 rating should be an option in this case

BT Student Broadband

Last minute student broadband offers and options

Posted on 2019-09-12 11:39 in Features Offers Hyperoptic Three Vodafone 4GEE BT NOW Broadband Plusnet Virgin Media

It's the time of year where students around the country are heading to university, either to start their studies or return for a new academic year.

Whether you're heading to uni for the first time, returning to your student accommodation or about to start out in a new student house share, now's the time to look for a good student broadband offer to keep you online over the next 9 months.

To prepare for student broadband season, we updated our longstanding Student Broadband Guide to reflect some of the student-specific offers available this year with student-exclusive 9 month contract offers from BT and student-exclusive cheaper 1 month rolling contract offers from Virgin Media.

Both of those option mean that you can avoid paying for broadband costs should you head home or go off on travels in the 3 months between academic years. But of course you don't need a special student exclusive offer to get short contract broadband from other suppliers, for example NOW Broadband, Plusnet and Hyperoptic also have competitive 1 month rolling contract offers that even undercut BT and Virgin's prices.

This year, we're also endorsing a mobile broadband option for the first time. Well, it's 4G or 5G mobile broadband technology sold as home broadband services. With 4G and 5G home broadband routers from Three, Vodafone and EE you may have to commit to a much longer contract, but you can then take your router with you wherever you travel during summer break. Vodafone even offer a 30 day rolling contract version, although you'll have to pay more than the cost of 3 months contract to get it.

Unlike most mobile broadband solutions, these have large enough usage allowances for many households. Three's home router even comes with unlimited usage!

Even if mobile data usually isn't strong inside your student accommodation, you may get a better connection from a router, or may even be able to get an external antenna installed to boost the signal.

We weigh up all these pros and cons and give you a table of all the relevant offers over on our Student Broadband guide.

Three Mobile Broadband Buyers Guide - Is Three right for you?

Can I get Three mobile broadband?

Three's 4G network is available to virtually the whole of the UK, while their 5G coverage is expanding rapidly.

4G coverage extends to some 99.8% of the population, although in some areas you might find that the signal is far better outdoors than indoors. This is always an important consideration when choosing a mobile broadband service, so make sure you check the coverage in your area before you sign up.

Our Speed Test survey shows that Three achieve an average speed of around 24Mb. This is broadly in line with most of their rivals, as well as entry level fibre broadband services. 4G+ is available in some regions, which can deliver significantly faster speeds.

The 5G network has launched in 66 towns and cities with more to come over the next few years. Three claim they'll have the fastest network, as they've bought more 5G spectrum than the other providers. All their SIMs are 5G-ready, so you can access the faster network on a 4G plan for no extra cost, as long as you've got hardware that supports it.

Can I get 5G on Three?

Three's 5G network is available in 66 cities and large towns, with more expected to be added throughout 2020.

The 66 locations where you can get 5G from Three are Aberdeen, Abingdon-on-Thames, Aldershot, Aldridge, Balloch, Barrow-in-Furness, Basildon, Bath, Bedford, Birkenhead, Birmingham, Blackpool, Borehamwood, Bradford, Brighton, Brookmans Park, Cannock, Cardiff / Caerdydd, Chatham, Clayton-le-Woods, Coventry, Crawley, Cullingworth, Derby, Doncaster, Dundee, Glasgow, Gorebridge, Grays, Grimsby, Guildford, Heanor, Hedge End, Hemel Hempstead, Huddersfield, Inchinnan, Ipswich, Leeds, Leicester, Leyland, Liverpool, London, Lower Stondon, Luton, Maidstone, Manchester, Mansfield, Motherwell, Neston, Newquay, Nottingham, Nuneaton, Peterborough, Plymouth, Preston, Reading, Redcar, Royston, Sheffield, Slough, St Albans, Stevenage, Swadlincote, Swindon, Telford, Westhoughton, Wickford and Wigan.

The network is expected to reach more places in 2020. These are not yet confirmed, but may include Bolton, Derby, Edinburgh, Hull, Middlesbrough, Milton Keynes, Rotherham and Wolverhampton.

What 5G mobile broadband deals are available?

Three offer one 5G broadband plan, designed specifically for home use as an alternative to a fibre deal. It's only available in London to begin with, and will roll out to other 5G areas in due course.

The Three 5G Home Unlimited plan comes with the Three 5G Hub. This Huawei-built device supports the latest Wi-Fi 6 connectivity, and allows you to connect up to 64 devices wirelessly at any one time. It also has a couple of Ethernet ports if you need a wired connection. The advertised download speed is an average of 100Mb, although your experience here will vary depending on how good the coverage is where you are - it may actually turn out to be faster!

There are two Three 5G Home Unlimited plans:

  • 24 months for £29 a month with no upfront fee
  • 12 months for £34 a month with no upfront fee

In both cases you get unlimited data. This compares well to other providers like EE and Vodafone, which put usage limits on most of their plans.

What other Three mobile broadband deals can I get?

If you aren't in the 5G area, Three have a range of other 4G home and mobile broadband plans to choose from.

For home broadband, you get the choice of two devices.

The first is the Huawei HomeFI Plus. This is a compact home Wi-Fi hub that lets you connect up to 64 devices at one time, as well as four more via a wired connection. It's available on three plans, all with unlimited data:

  • 24 months for £22 a month with no upfront fee
  • 12 months for £27 a month and £29 up front
  • 1 month rolling contract for £30 a month and £29 up front

The second is the Huawei AI Cube. This AC-rated wireless hub handles up to 64 connected devices, and also doubles up as a smart speaker. It's got built-in Alexa support from Amazon, and you can use it to voice-control any smart devices you've got in your home. It comes on two plans, both with unlimited data:

  • 24 months for £25 a month with no upfront cost
  • 12 months for £32 a month and £49 paid up front

In addition to that, Three have a mobile broadband router that you can choose if you need to use it when you're on the road. This device is the not so catchily named Huawei E5573bs-322 4G Mobile Wi-Fi, which is the size of a credit card and delivers four hours of battery life. You can get this on over 20 plans, ranging from unlimited data on a 24-month deal to up to 24GB on pay as you go. It isn't a home broadband replacement.

And then there are some SIM-only plans that you can use with your own hardware, with usage allowances of up to 100GB a month. There's tablet plans, too, which is a great way to save on a new iPad - or at least spread the cost over a longer period of time. The data options here give you up to 40GB on a 24 month contract, or 24GB on pay as you go, with upfront costs.

Should I choose 5G or 4G mobile broadband from Three?

Three are already a popular choice for home broadband services. Because they don't come with any data caps they are a true alternative to a fibre plan.

5G Home Unlimited is an excellent option. It's fast, it's affordable and it's unlimited. But it comes with one pretty big caveat - it's available hardly anywhere. Despite Three having launched 5G in 66 places, you can only get Home Unlimited in London. And even then the availability is not city wide. If you are in range, with good coverage, then it's worth considering.

If you're in an area with a weak signal you'll still get a service, but it will drop down to 4G speeds. You could take a punt on the service being upgraded during your contract period, or you could just save a little money by choosing a 4G option instead.

The 4G plans are also pretty attractive. They aren't that much more pricey than an equivalent fibre deal, but you do have to be willing to choose a very long contract (two years) to get the best value.
