Lovely little cube for 4g internet. However, crap is all I can say. Best I've ever had was 10mb, usually it's not above 3mb. I live in a flat, however it sits on the window sill and if go further in to my flat, I can get 38mb on my mobile which is on Tesco mobile (using O2 network). When I bought it, 5g was rolling out the followimg week, that was in July and 6 months later, I'm still getting 1mb of 4g.
Cannot wait until my contract finishes. P.s. this was written on my mobile data as the wifi waste slow

Gloucester Three Mobile  
Have had broadband supply from 3 for 2 months, during that time we have lost signal numerous times, for up to 5 days. Customer service is appalling, do not seem to care, say someone will contact within 2 days, and will try and get signal back within 7. Have never had any problems with previous suppliers. Only have 1 stars because you cannot give none.

East London Three Mobile  
Absolutely ****** service, I was told by their website that 4G and 5G are available in my flat and that internet speeds were a minimum of 20Mbs.

Once I received the device it wasn't even receiving 4G, the maximum speed I received was barely 700 Kbs ( emphasis on the K ). After calling customer service, I was answered by an inexperienced technician in a different country that was reading a pre-set script and had absolutely no idea about what he was talking about.
His main recommendation: " Put the device next to the window it will work have a better signal "

Being desperate for Wifi, I opened the window and put the device almost outside which is when I finally reached a speed of 1Mbps ... I decided to cancel the service afterward and was told by the company to send the Hub back by post, they also had the nerve to tell me that If they do not receive the device or if it was damaged I would be charged with a 350£ penalty ( For a ****** Huawei Hub that does not cost more then 20£ )

I DO NOT RECOMMEND AT ALL

London Three Mobile  
i live in very rural west sussex. My talk talk broadband -fibre, was peaking at about 27mb. Then my price went up out of contract so i switched. I had looked at mobile as i knew the mast was only about 1 mile away and was 4g+ enabled. I am an existing 3 customer so knew i had coverage. I bought the alexa enabled Huwawei AI cube and pay £20 a month. i am getting a connection of around 90mb now. There is a cap of 1TB per month so keep your eye on your usage, you can do all of this on your phone with the app. if you have doubts, simply tether your existing phone to your pc/laptop/firetv stick etc and see if it works before you order the hub. Its excellent, the hub, and has alexa and a nice bass speaker in there so you can pair your devices to it for sound as well.Much better and faster than wired broadband out here in very rural west sussex.

Horrible horrible broadband. As a user I have never been so helpless. Three broadband charged me double the bill in one month. When I asked for help on customer care, they made me wait for 40mins and I am kidding. When I went to the store they asked me to call the customer care. Horrible and pathetic service. Never ever opt for this please if you want to stay in peace.

London Three Mobile  
Our Three signal is good (looking at other reviews not everyone checks first). We are in a semi rural area so congestion should not be much of a problem. So far internet speeds have averaged 40-50 MBS, fine for 4k streaming. There is a bit of a lag as you start up, most of our speed tests point out this would not be good for gaming. Our previous fibre was not half of this due to distance from the centre. Reliability has not been 100% with a few days of poor service but compared to BT its about the same. Data transfers, especially uploads, have been extremely quick.
Customer service has been challenging at times, you get get the "we want to help you" type of approach but few will understand exactly what you are saying.
We have the Huawei AI cube (more of a cylinder really) which supplies the whole house fairly well. I use an Ethernet cable for the TV which seems much better for stability than wifi. I had a go at range extending but there seems to be an incompatibility with my tp-link plug in system. I have simply moved the antennas on my remote computer.
All in all very happy so far.

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?

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 find coverage to be spotty. However Three have one of the country's largest 3G networks with over 98.3% 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 and 4G networks, with colour coding showing which areas have strong coverage indoors, and which will only get good signal outside buildings.

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 tariff.

However, you must own a 4G/LTE capable device in order to enjoy the 4G speeds your tariff will include. 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.

Large usage allowances

Three offer unlimited data on some deals making them a viable alternative to a fixed line home broadband package for moderate users.

If you're in a broadband not-spot and can't get fibre, then Three's HomeFi router means you could get respectable speeds over the mobile network. If you don't use your landline for calls and you get good quality 4G or 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 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, consider signing up for one of Three's unlimited data plans. If you go over your monthly usage allowance, you'll be charged 1p per megabyte, which can very quickly add up - however Three should inform you before you exceed your allowance.
