    There is a special place in hell for whoever thought Mifi Internet packages were a great idea for homes. Maybe if ypu live in a van, sure you can make an argument for that but a home. Please do not advertise those as a great Internet deal. Its not. You'll be pulling your hairs put in no time. The volatility in Internet speeds is ridiculous. I had the unfortunate luck to have found a room in a house in London with a Three Mifi package. Worst decision I have ever made. Don't take for granted a good Internet package that is overkill for your needs. Seriously. You'll want to watch a movie, you can't. You want to play video games online, keep dreaming. I have honestly not seen an Internet as bad as this one. I would actually rather have dial up Internet. St least I know what I'm getting.

    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've had three broadband for over 4 years now as BT or sky isn't an option. As for fibre. That's a pipe dream where I live. At first it was OK, but over the last few months (start of 2022) three's broadband is getting worse ! I have a good signal for 4g. But forget it.

    Truly awful, both in terms of the service itself and the customer service.
    Before signing up to Three Mobile Broadband I called them to check coverage in the location I would be using it. I was told coverage was good. It is not. Coverage is very, very poor. I even had the router outside and tried every direction on several occasions.
    I have reported this to Three who are refusing to accept this and demanding early termination fee. They are an unscrupulous company.
    I have now purchased EE mobile broadband and receive very good coverage and good customer service. You get what you pay for!

    Been with 3 since time began, I didn't have any issues until I moved to North Wales. The broadband was shocking could bearly use one device with it. I also only have 2 bars on my mobile phone and that's even after it was changed to 3G as 4G was non existant.I don't like to complain but it's the honest truth.

    We have found the Three mobile network is a waste of money. Lucky we didn't sign up to a contract because it would have been a disaster.

    Three's signal is unreliable and their broadband in our area is regularly throttled.

    Living in a seaside, rural area doesn't help, especially when visitors overload the network.

    Three's customer services are also poor; they don't answer social media messages and nothing has been resolved for us over the phone.

    Three's mobile PAYG has become expensive over the past few years, and it just isn't value for money any more.

    Absolutely useless. Have been with the 3 pay as you go for ages with hardly any problems so I decided to try their 4G broadband. Great to begin with but now the signal is useless even with the 3 mast at the end of my street!! If you need mobile broadband don't use 3. You will just end up wasting your money.

    My HomeFi broadband gets about 2mb if I’m lucky.
    Save your money and opt for fibre if you can.

    It's just a bit sad.

    I’ve been with three for over a decade, I have 3 phone contracts with them for each of my family members.

    Their prices are great for both sim only and monthly phone deals. My husband is on sim only and his price reduces every year. My daughter gets the latest iPhone every 2 years, at the lowest price.

    The customer service is great, very helpful, not a long wait, and quite friendly.

    But even with all that, they have a huge problem. THEIR NETWORK.

    I never get signal anywhere. I don’t live in anywhere remote, I live in a the suburbs of London. But god in some places in my town, I get terrible no signal at all. Zero bars. People call me and can’t get to me.

    When I’m out with friends their networks seems to work just fine, and they’re all using different networks, vodaphone, EE, GiffGaff. It’s always just Three.

    The internet is also quite unreliable. My phone is suppose to be 4G internet connection but I don’t think I’ve ever experienced 4G, I barely get 3G.

    I got a few messages in the last few years saying that they’re improving the network in my area but I’ve not seen any change. At all.

    They’ve also removed the Three benefit of using my data abroad. That I’m sure they don’t have full control over but it was a huge reason I stayed with three all these years despite the network issues.

    Anyway,

    If you’re looking for a good honest, cheapest on the market, affordable network with good customer service and you’re not fussed about internet speed. Three is for you.

    If you at all rely on data outside then stay away for your own good.

    We were promised download speeds of 200+mbps. Our actual speeds have been peaking at 2mbps on a good day. A few months ago customer service told us that there was maintenance under way that would "definitely" be fixed by the 24th of December. That date has come and gone and if anything our speeds are worse now. We followed it up on Twitter and were told the works would now be finished next June at the earliest! Absolute joke. When we signed up for the contract we were told connections in our area were great and there was no mention whatsoever of any maintenance works that would make it borderline unusable for the first 12+ months. Now we're stuck with this lousy rip-off excuse for an internet connection for another year as we can't afford the cancellation fee. Please, PLEASE do not make our mistake.

    Had it for 8 months, generally reliable with around 30 to 45 average mbs download, and I am on the edge of the city in semi rural area. Has lost Internet twice in 8 months for about 12 hours each time, but 98% of the time it's fine. Plug and play, better than slow old phone broadband that only gave 2mbs here.

    Having been a three customer for several years I've seen the good, the bad and the ugly.

    The good: when it works it works. That said, it works where there is no major demand in a given area such as some towns / suburban areas. Have been using one of these contacts in the TN38 Hastings area (4G) and it works well for the type of use, with speeds of around 6-17 mbps down. Similarly in the TQ2 Torquay area the service works well with similar speeds to the above.

    The bad: London... Most of the areas I've tried it, it has failed or offered poor and unusable performance. SE14: 0.2mbps down 10% of the time, no throughput 90% of the time. NW1 : 0.6mbps down. WC1N: 0.9mbps down.

    These speeds simply don't constitute an acceptable level of service in my opinion.

    The ugly: customer Service... They simply do not know what they are talking about. The speak the language of upgrades and maintenance as the issue and reasons for the slow or unusable service, coming up with a variety of poorly scripted excuses, looking past the fact that it's been going on for years. Then in the next breath they are trying to get you to upgrade to 5G for another two years to solve the problem... Really? I'm sorry but I am not convinced.
    I've switched to Vodafone and EE at a far higher cost in the problem areas and the service has been rock solid so far, particularly on Vodafone 4G.

    I've been with 3 for 8 mainly trouble free years, until this year..."Upgrading" work was done on my local mast and now my service is ****... Download as slow as 0.8mbps, upload at 0.03 mbps...easier to put a hysterical emoji and a turd than post those figures. Absolute piss take. To be fair though, the Live Chat handlers are always courteous and try to be helpful, but aren't...
    Do yourself a favour and give them a very, very, very wide berth

    It does the job for watching YouTube, Netflix etc. Can struggle with online games like GTA, I've had speeds between 5.5 & 35 mbps it doesn't have a reliable average speed. All in all it's OK.

    I have read all the reviews below and felt disappointed by many of them. I ordered the dongle mobile WiFi for use in my camper van. I think I have had it for nearly a month now. As a test I shut down my Virgin set and used purely the dongle for TV my wife and my internet use, and I have used it for heavy work. A couple of t8mes during the England vs Scotland match we had a bit of spinning circle in the middle of the TV. I have calculated we use approx 2gb or is it 2mb download per day. This is normal everyday usage for us. So we have had no problems. Speed was brilliant. No internet delays. I would say at times it was better performance than our Virgin contract at £64 per month. I opted for the £12 per month for 10 wotsits per month. Now we have tested the network etc we are fast running out of the gb or mb so I have had to go back to our virgin setup. I want to upgrade and go up two levels of down load package with the dongle now so we can be 100% on the dongle. I will save money without a doubt for what use we want from the internet. There must be technical or end user reasons why people are having problems, we had NONE. I have not had to use the support service that’s why I could not put any stars against them. I would highly recommend this product/service. If people had problems and I did not then the company has listened to the gripes from feedback and sorted them out before we brought into I it.

    Absolutely terrible. I have a Mobile and Home Broadband contract, in Central London Zone 1. Out of the blue, they decided to stop the service for a month. without any notice.Zero WiFi. It took 2 days on the phone with the absolutely hopeless customer service, based in Asia, to find out its for ‘maintenance work’.
    They offered a compensation of an ‘extra month for free’. Extra month of what ? No service. Absolutely shocking. We are in a pandemic, people work from home and need Wi-Fi, thank you for cutting us off without notice. I cancelled both contracts and they said I don’t need to pay a penalty... penalty’s for paying for a service it is not existing. The connection, in central London , was rubbish anyway when it worked sporadically for 2 months ( I got a 5 G contract but I was barely getting a 4G with the need to restart the router at least once a day). The worst provider ever, almost criminal. Liars to get more customers that’s all.

    I'd give them no stars if it was possible,abysmal download speed less than 1Mbps at the moment they're simply unable and unwilling to meet their contractual obligations and I suspect any good reviews on here have been sent by their employees,Avoid like the plague is my opinion.

    The worst experience ever! I switch to 5G broadband wanting to reduce cost of broadband and stop paying for line rental. Even though I live in central London the 5G signal kept dropping, latency and drops in connectivity were common. Hours wasted with tech support on the phone they finally agreed to allow me to terminate contract and send equipment back. Five months later I’ve realised they are still taking payments and now are telling me there is no evidence of agreement to allow me to terminate contract early. I’ve raised complaint and am still waiting on outcome. Whatever you do get everything in writing and take names of whom you spoke to. Do NOT trust!!!

    I have been using three for years we had three phones and a mobile broadband dongle then a Huawei router , problems started when 4G rolled out everything became unreliable, not so bad on phones butemail through router became unreliable as streaming video has become more widely used the router situation is awful. however setting it to 3G does give consistent 4mbit down and 6 up so Netflix etc works ok , the real issue is customer service or lack of it I have now got rid of the phones and moved to different networks the router SIM has 9 months to go but I'll move to another providor , they clearly rate shape their network otherwise how can you have a full signal and no data throuput !

    I have joined 3G home broadband almost two years now and their service has never worked properly. I have asked them to terminate that contract for almost two years and they kept telling me they need to do troubleshooting each time I called. Their broadband has been extremely slow and in most cases did not work at all. I have told them since you cannot provide me with the service promised to terminate the contract and they never did.

    Now they left me without no choice but stop paying them. Now they are sending us letters to pay the bill or they will send us to court. I'm refusing to pay for a service that has never worked or provided. They have kept us by force for almost to years and without broadband, in-fact I have to use my phone internet to do my work and has costed me even more money.

    joined 3 several years ago and was initially reasonably happy with the mobile broadband service which l utilised at work. Moved jobs recently and decided to quit 3 as the coverage poor in the Peak District. That's when the hassle began. l contacted 3 via the net to cancel what had become a simple rolling monthly contract and waited for a final bill that failed to arrive. lnstead l received a letter from a debt collection agency stating that my account was in arrears and that my credit rating would be ruined if payment was not made. A few days later a bill from 3 appeared which l paid, but l still find myself pursued by the debt collectors while attempting to resolve the issue directly with 3 who seem utterly clueless. my advice is to steer well clear of 3.

    Moved in a studio flat on the 19 of February 2021, after searching on the net for a quick easy to handle broadband provider I decided to go for Three 3 mifi mobile broadband. Down load speed between 6.9 Mbps up to 18 Mbpps (late night) 2 devices connected, I am pretty satisfied with the service. And it is the best cost effective solution on the market for an unlimited download mobile broadband 2 years contract.

    Absolute piece of s... Impossible to use, the connection disappears for no reason. In the last hour, I had to reconnect maybe 30times.

    Terrible. Was sold a 5G connection to my address but when I was experiencing below expected speeds checked the Three website to be told that 5G was not available in my area. When coming to cancel the contract I had to enter my details 3 separate times only to be cut off mid conversation with the person who was meant to be helping me cancel my contract. 0/10, Would never use Three again.

    7 days after purchase Download speed 11.4 MBPS upload 4.9, handling a laptop and 2 mobiles connecting at the same time with no issues at all. Pretty happy very easy set up you are online in no time after unboxing. No hassle, It is a small portable device highly recommended.

    If there were 0 stars, that would be my rating for Three. Their broadband speed is at modem level for most of the day, the customer service provides no help at all but pesters you with standard blah blah blah. They wouldn't even let you out of your contract w/o cancellation fees, even when they're clearly not able to fulfill their part of the contract. If you want so spare yourself a whole lotta trouble, do stay away from this company. They are an embarrassment in every aspect of their doing.

    Please stay away from Three. Shocking speed. Not able to watch a Facebook Watch video without disruptions. Sucked into a 2-year contract.
