    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

    The most embarrassing mobile network ever! Do not listen the the good reviews as their is only 1% of good reviews and are most likely fake. Anyway to the point it’s the worst mobile network ever, Not once have I ever got 5g even though I’m a few blocks away for the 5g tower, I struggle to get 4g and consistently on 1 bar.

    Travelling from usa for 3 weeks, decided to use a UK mobile while here.
    Carp hone Warehouse suggested my3 mobile, so I paid £25 for a SIM for a month, and bought an LG Nexus to use, which was a big mistake in itself.
    My3 network dropped Jan 2 overnight, customer support has been unreachable, the website slow and no help at all
    Will be taking the phone and the SIM back to the shop where I purchased it, probably won't get my money back, but will spend many hours panning my3 mobile on as many websites as I can.
    Waste of time and money

    Avoid at all costs. They messed us around for 6 months claiming they were fixing the poor connection, only to later finally say that they can’t offer 5G in SW London whilst their website and (Indian based) employees stated otherwise.
    Shocking experience. Avoid avoid avoid.

    I have been a loyal customer with 3 for over 10 years prior to February the broadband was ok however it has slowly but surely got absymal constantly . Lags when my son is on his ps4 and he can't understand I work from home and it constantly throws me of my network and calls and we can't watch Netflix or now TV as Constantly lagging I have 1 year on my contract I have complained several times and they have tried everything I will be cancelling and taking them to small claims if they put a bad credit mark on my file I have 4 contracts and have just cancelled one phone contract and will be moving the others to different providers very soon they are terrible and reading all these comments on hear bring home just how bad they are now they are going to lose lots of customers

    Awful company. 2 years ago I went to the three store in Bedford to do an upgrade. Unbeknownst to me I was also given a whole new contract despite only wanting an upgrade. For over a year I was charged for 2 contracts. As soon as I realised I was being double charged I stopped paying the direct debit that had no correlation to my phone bill. I started receiving letters for a number I've never had asking for money. After receiving a letter stating that the number had now been disconnected and the remaining balance would soon be sent to a debt collector, I paid the balance and considered the matter resolved. I have now received requests for more money. On contacting Three I have been told that they have no record of the disconnection/cancellation letter despite having records of the other letters and I am therefore liable for the £70 they want from me.

    Avoid them. Utter cowboys.

    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.

    Several months with their 4G MiFi, the device is located by the window on a high floor in Central London. Average download speed 2 to 3 Mb/s, when it works!
    Often continuous disconnection and reconnection. Very unreliable internet. I suppose their 5G must be similar as it is newest network and they are not able to sort out their 4G. I've got mobile data plan with BT and it has excellent coverage in my home, so it's a Three service issue. I do not recommend it at all.

    I'm with three network for the last 7 years, and got 3 contracts with them. I had a technical issue with my HTC One x recently and when contacted Three, without explaining things they transferred the call to HTC, saying the manufacturers handle the repairs. It was not the case in the past.
    Anyhow phone was collected on 7th of October and they said it would be returned in 5 days.
    Even after one week I didn't receive my handset. Spoke to Three/HTC without any luck. Sent 2 emails and a letter to Three but still they could not solve the problem. They didn't bother to provide me with a loan phone even.
    Three wanted me to request for a compensation from HTC. But i didn't sign up with any manufacturer to ask for a compensation or deal with them. It's Three who should coordinate with them to make sure that they provide with the service that they promise.
    The phone was finally delivered on 31st of October, that's after 24 days.
    Well, what sort of a service is that.
    On top of that I received a letter from their Director of Customer Services to say that I should take this issue up with Ombudsman Services since they couldn't resolve my issue.
    I was with Vodafone, and thereafter with T-mobile before joining Three. The only reason for the switch over was Three was much cheaper, but now I realize that's a big mistake.
    Although they're cheap, their Customer Service is really horrendous, and their network coverage is also very poor even in London.
    I would never recommend any one to join Three, and also I have 7 more contacts among my family members with Three, and would make sure they switch to another network when their contacts are up for renewals.

    I've only had 3 4G home broadband hub for approximately 4 months, it's supposed be fast and for multiple users. It's awful it constantly goes round and round no signal or stops altogether, I used to have virgin which was great but just can't afford it anymore, I'm in a 2 year contract so pretty gutted, in my area anyway it is awful :-(

    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!!!

    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.

    I had good service until I gave the notice to cancel my 4g mobile wifi dongle. Then problems started with my wifi.

    This is ludicrous, others, take warning.

    We bought this because of the immediacy - as opposed to waiting for installation. My advice: ALWAYS WAIT FOR INSTALLATION OR SEEK ANYTHING ELSE. This device is absolutely awful, genuinely the worst internet provider I've ever used. The people on the lines for customer service are really good but it ultimately does not matter because the product itself is categorically useless. I've had it for seven months - in which time I've moved three times - and every single place I've used it, it has varied been working extremely slowly - or not at all. Seriously, do yourself a favour and steer clear of this one.

    I had contract with 3 uk for last 10 months was slow i rang up soo many times to solve this issue however, it was always ended up "making so many excuse and not taking it seriously so i got feed up from keep calling at them!
    At the end up 10th month i got £40 extra charge than normal i rang up the excuse was that i have used extra data even though from beginning i was allowed to use (all you can eat data) so i remind the person i was on the phone to he sayed sorry we won't charge you extra anymore and will not going to charge you for next month payment so i waited one more month on the start of next month again this happened i have been charged even 50 extra this time so i have cancelled the contract! Unfortunately i ended up with losing over 100 pounds and 50 for the cancellation policy. This is how they treating their customers! I have made a complaint for refund but nothing has been done since last month. Please please reconsider if you getting pay as you go or contract with 3 as i swear to god you will regret it. As all they want is ur money bland not giving you anything back!

    I took out a contract with 3 and couldnt make or receive calls in most of my daily locations. To cut a long story short. They lied to me. They cheated me and they robbed me. When i had finally heard enough falsehoods and broken promises, i stopped paying them and the sent debt collectors after me. Thankfully the debt agency investigated my dispute with 3 and cancelled my outstanding debt. I am grateful to them for this decision but ABSOLUTELY LOATHE 3 AND EVERYTHING THEY STAND FOR. GIVE ME MY MONEY BACK!

    Switched from Talktalk landline based broadband to 4g. Speeds were poor but on the whole reliable. Sold a pup by Three with carrot of no landline fees. Speeds are worse and TV streaming is a chore. Customer service is appalling. Now stuck with this shockingly poor company for 24 months. AVOID!

    Tried to cancel last month using online chat. As told it was being done. Today get a call demanding payment for the month as the cancel request didn't go through.

    I find it quite convenient that I'm at fault and need to pay for threes mistake. Typical rip off Britain style of operation. Take Advantage of your customers.

    Cancellation is a pain. Not getting service until I pay my "outstanding" bills for service that I'm not getting.

    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.

    This is the most unreliable Internet I have ever had and we live in Reigate in Redhill, which is not far from major connections. Do not buy this. If you’re counting on stable Internet, need to work from home or do conference calls. Please also be aware that for some reason they put on parental controls that you only can have removed if you go to the shop. Do not buy this product. It’s crap.

    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.

    With Three Mobile, I am getting around 75 Mb/s download speed and 9 Mb/s upload speeds, in semi-rural West Yorkshire.

    Reliability has generally been very good, and I now have an external (omni) antenna mounted on my roof (connect to my Huawei B593 router) so I expect reliability to be even better now.

    Customer service is usually very good or excellent, with the odd exception. But I find they generally look after me very well.

    Definitely recommended.

    Absolutely useless, constantly shows as 4g but no connection whatsoever. And attempts to contact anyone is another pointless exercise. Their website cites no problems and brilliant service where I live. But nothing could be further from the truth.
    Another company that lies to its customers, takes their money, but really cannot be bothered to actually provide the service they are paid to provide.
    I am so tempted to cancel my payment as I should imagine they would definitely contact me then.
    Frustrating, unreliable, dishonest in their service claims, avoid at all cost

    I thought this would solve my BB problems as i live in the countryside.
    The signal drops & rises,surely i should be able to get a reliable 20meg d/load speed.Some times it drops to around 3-4 meg d/load.I need to shop around once my contract is up.

    Woefully inadequate customer service, clearly under trained, didn’t understand whether vat was included or not when asked, (three different members of staff), two months in succession spending an hour at a time to try to resolve, but “computer says no”. Six year customer now looking at other opinions

    So Three UK think it's alright to offer you a refund one day and then say no sorry our guy was wrong the next day! Their customer care service is shocking, avoid like the plague... They also say they'll cancel your contract months ahead of time but they don't... You'll still need to go through a painstaking conversation with them a month before it should have cancelled :-/ not impressed

    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.

    Bad connection, bad customer service, 4g speed was as slow as a dial-up connection. difficult to cancel even after contact ends.
