Customers of Three UK Suffering Network Connectivity Woes UPDATE5

Friday, Dec 1st, 2023 (10:54 am) - Score 36,880
Three-UK-SIM-Card-on-Red-Gradient-Backdrop

Some customers of mobile operator Three UK are this morning reporting network connectivity and signal problems from a number of different locations across the country, which is preventing users from making or receiving calls and stops mobile data (broadband) via 3G, 4G and 5G connections from working.

The issue appears to have started at around 6am this morning (Down Detector) and complaints are currently still rising, although at the time of writing it doesn’t yet appear to be impacting the majority of their customer base.

A spokesperson for Three UK said (here): “We’re aware that a small number of customers may be experiencing issues with our network this morning. Our engineers are working hard to fix this as soon as possible. We’re so sorry if you’ve been impacted by this.”

UPDATE 1:53pm

We are not at all convinced that this is only impacting a “small number” of customers, particularly since the issue seems to be growing and is now also impacting yours truly and nearby family members (it wasn’t this morning). The issue also seems to be hitting MVNO operators that use the same network.

UPDATE 3:22pm

Three has just issued us with another update, but the only real difference is that they’ve now removed the “small number” wording 🙂 . A spokesperson for Three UK said: “A number of customers may be experiencing issues with our network. We are aware of what the issue is and our engineers are working to fix it as soon as possible. We apologise for any inconvenience caused.”

We have responded to request something more informative than the usual canned statement. Meanwhile, some customers are seeing their 4G and 5G data connectivity return, although it seems to be quite intermittent.

UPDATE 4:25pm

Complaint volumes about this issue appear to have skyrocketed this afternoon. Seems it may continue to get worse, before it hopefully gets better. Sadly, there’s been no solid information from Three UK to explain what is actually happening, save for the vaguest of canned statements. Customers deserve better from network operators, but until there’s some change via Ofcom then vague statements are all we’re ever likely to get.

Meanwhile the service status page on Three UK’s website continues to claim there are no network issues.

UPDATE 6:03pm

We’re seeing some reports of connections returning. Meanwhile, Cloudflare has released a chart that shows how the outage has been recorded on their internet traffic trends for the operator’s network, which highlights a clear drop around 15:00 UTC and it hasn’t returned, yet.

Cloudflare-Radar-Three-UK-Dec-1st-2023

At the same time Gamma’s service status page may give us our first real indication of the cause. According to that page: “3UK have identified a faulty device in their network causing intermittent disruption to service. They are working to replace this device with delivery to site anticipated by 19:00 and are reviewing what additional mitigation they can put in place to minimise disruption.”

UPDATE 2nd Dec 2023 @ 6:14am

Three appears to have restored data connectivity last night via various unspecified network mitigation measures, while some of those experiencing calling issues have informed us that they seemed to have been resolved in the small hours of this morning. But we won’t know if there’s still a major problem this morning until everybody starts waking up to use their mobile phones.

Some posters have also reported that O2, Vodafone and EE were impacted by the same issue, but their complaint volumes are still relatively low (measured in the hundreds, rather than the tens of thousands) – not even remotely in the same ballpark as Three experienced. Most of the rise that does exist could also be explained by customers of those networks being unable to contact those on Three’s service.

    I moved from 3 a while back and it was the best thing I did as I’m normally in rural areas. 3 are great in urban areas but I tend to find they are poor in areas outside of cities…

      Agree with you 🙂

      Once you leave into the country side it’s a different cup of tea 🙁

      One can check (and improve) the community collected data for 3 and others here
      https://www.cellmapper.net/map?MCC=234&MNC=20&type=LTE&latitude=53.8739833030975&longitude=-2.5519363713670664&zoom=7.251211111832331&showTowers=true&showIcons=true&showTowerLabels=true&clusterEnabled=true&tilesEnabled=true&showOrphans=false&showNoFrequencyOnly=false&showFrequencyOnly=true&showBandwidthOnly=false&DateFilterType=None&showHex=false&showVerifiedOnly=false&showUnverifiedOnly=false&showLTECAOnly=false&showENDCOnly=false&showBand=28&showSectorColours=true&mapType=roadmap&darkMode=false&imperialUnits=false

      Change between all the 4G Bands that 3 is using 🙂
      as not all are enabled in all locations 🙁

      The higher the frequency band, the
      more difficult it is for the signal propagation ….through objects (trees etc.)

      Funnily enough, I live in semi-rural and moved to Three (SMARTY) after terrible experience with VM02. 02 would frequetly show 3 or 4 bars but deliver excrutiatingly slow service with frequent drop-outs.

      Three has been really good, up until today when they have let themselves down by experiencing a major outage and not even updating their website or ‘Socials’ with this service announcement.

    3. Avatar photo Ad47uk says:

      Seems to work better than others at my partner place and she lives in the stick, sure I have to either go into the kitchen or the bathroom to get a signal, but that is better than other networks. Thankfully, smarty does wi-fi calling, but even that was not working today, so must have been internally where the problem was.

    4. Avatar photo Sam P says:

      I found Three to be outstanding in rural areas here in south-west England.
      I can be in the literal middle of nowhere and have gigabit 5G speeds, it’s really surprising.
      Meanwhile my Vodafone or EE sim will have absolutely nothing.

  2. Avatar photo Tom Dick and Harry says:

    Looks like the 4G has gone down.
    3G I can make at least calls and sent SMS (but no internet)
    Not sure what the 5G is like, as no signal here.
    Do they have 5G “SA” network running somewhere already?

  3. Avatar photo Jammie says:

    My smarty sim went to emergency calls for 30 mins this morning between 10am – 11am.

  4. Avatar photo Karen says:

    Riddle me this: I have a Smarty SIM in my phone, I can’t use data on it ATM for the outage.
    My home 4G router also uses a Smarty SIM, it works perfectly! Both devices are currently using the same phone mast…. Go figure

    1. Avatar photo Raymond says:

      Very similar experience
      My smarty SIM in my phone is not connecting at all and my 4g router with smarty SIM was working fine.

    2. Avatar photo I love Starlink says:

      Three told me this was possible. My wife’s smarty phone was working but my Business SIM is not. Same place same cell. It’s dam odd I grant you!

  5. Avatar photo M says:

    Oh yeah, just realised why I wasn’t getting a text message, as i’ve got no damn signal whatsoever on three..

    Luckily i’m dual sim..

    1. Avatar photo Keith says:

      Mine is completely down too. Unfortunately I’m not dual sim – so interested to know more.

    2. Avatar photo M says:

      I spoke too soon

      EE now absolutely fubar where I am. Down detector says similar.

    3. Avatar photo I love Starlink says:

      EE stayed up for me. In fact I didn’t even know they were affected until I came here.

      @keith. Some phones can take 2 physical SIMS. Either 2 physical sims or 1 physical SIM and an eSIM which is where there is a blank SIM module in the phone and you can download operator details into it and then delete the when you are done with the service or want to change. It’s secure in the sense it’s encrypted in the phone and you need to scan a physical code to get it to connect/download

      For example I have an Iphone where I have EE on Physical SIM and Three Business on eSIM.

    haven’t they been banging on about their shiny new cloud core? have the clouds turned a bit grey?

    Perhaps a harbinger of what’s to come if VodaThree comes into being, with customers then only having two other choices.

    1. Avatar photo Andrew G says:

      What’s especially worrying is that the company have stated a piece of equipment failed. If one piece of kit going down can bring the network to its knees, then that’s a single point of failure and would show that Three are not fit to run critical national infrastructure. If we had a competent regulator, they’d investigate vigorously and make sure it doesn’t happen again. But as it is we’ve got the poor joke that is Ofcom, and they’ll do nothing.

    2. Avatar photo Me says:

      @AndrewG oh get real! Even all broadband providers can have major network outages due to one piece of equipment failing. Sure they can double up on every single piece of equipment and every backbone connection but then they can charge you double for that privilege too. And pay fines to government for breaching CO2 emissions due to all the extra equipment working. One frigging day isn’t going to ruin your life. They replaced the faulty equipment which most likely cost a lot.

    3. Avatar photo XGS says:

      @Me No ISP worth their salt will have any single point of failure outside of the very edge where the customer connects so a failure there will impact a limited number of people.

      No reason to have a huge proportion of a network reliant on a single chassis let alone a single line card.

      Having redundancy isn’t some unusual thing it’s the standard thing. Even very small ISPs have a couple of NNIs with each of their network providers and a ring for their connectivity to the wider Internet.

      Very unusual to have core network with no resilience and it usually happens in error.

      After a massive outage Rogers in Canada not only had to modify their network to improve resiliency they ended up building a parallel network with a different vendor.

      Believe BT have a multi-vendor network for this reason too, to provide protection against a software issue wiping out a network let alone relying on one line card.

      Mobile network cores should be delivering 5 9s reliability. No excuses.

    This outage has caused a great deal of suffering. Three shouldn’t be allowed to do stuff like this, especially on the coldest day of the year of all days. People could be freezing to death!

    I’ve just had to endure a treacherous two hour walk after I was unable to summon loved-ones, or an Uber to pick me up from the Gym.

    It’s just as well Apple Pay use a different network as I was at least able to purchase a Pumpkin Latte to keep my body temperature up.

    I’m supposed to be click-collecting some christmas presents later but goodness knows how that will work if the internet is down.

    1. Avatar photo Gina says:

      Get real, all systems have problems at times that are outwith the operators immediate control. Three (Smarty) has by and large been very reliable .. my 4G data connection on which I an replying is working. So unfortunately you will just have to patiently wait for a resolution to the problem

      I suppose I might as well, because I have no bread to toast, since I can’t even order my favourite spelt and kamut sourdough small-batch loaf while the network is down.
      Three just don’t seem to value their valued customers. Meanwhile, us ordinary folk suffer.

    7. Avatar photo Bob honeysuckle says:

      Apple pay doesn’t use a different network. It uses NFC to send your card details to the shops card machine and the shops broadband connection. Its not like three decided to do this.

    8. Avatar photo Ad47uk says:

      It is a pain, but these things happen, it is to be honest the only problem have had since I have been on Smarty. If you rely on Apple or Google Pay only, then you are a fool. I keep my debit on me just in case, even when use Gpay. Also, normally keep cash with me as well.

    9. Avatar photo I love Starlink says:

      “If you rely on Apple or Google Pay only, then you are a fool.”

      Erm.. If for some reason the Visa/Mastercard network goes down it will STILL accept an Apple payment. Why? Because Apple Guarantee EVERY payment. Also Apple Pay/Google Pay can’t be nicked.. God luck buying your worthers originals when there is a problem with the shops Broadband or the payment networks.

      The “fool” is the person who thinks a debit card is better!

      You sound like some elitism moaning about first world problems no one literally cares about lol. You poor thing.

    11. Avatar photo Ad47uk says:

      @I love Starlink, I never said rely on debit card only, Also ways carry cash, most of the time that will be accepted when everything else fails, I say most as a few weeks ago I could not pay for stuff in poundstretchers as Openreach decided to update their connection when the shop was opened and tills these days seem to need a connection for even the basic of things. it will come back and hit us one day.

      I have gpay or what ever they call it these days set up on my phone, don’t use it that much, also have a debit card, contactless disabled and cash and if I must, I can pay with my watch, but that uses Curve and still need my phone to work.

    12. Avatar photo Ad47uk says:

      @james, years ago, people could go out and use a call phone if they had to, also the majority of people had landlines, the way it is going, they will become less reliable if people have them at all.,

    I have a 5g router with a 3 sim in it. To be honest i get over 450 meg down on it whereas EE is barely 40 meg. So if it goes down for a while once or twice a year to me its still worth it compared to other networks which also go down now and then.

      I Was in that position 18 Months ago but gradually the network has become more & More congested & three simply refuse to do anything about it now our mobile broadband slows to less than 2Mb at peak times

      My d/l speeds have been fantastic, at about 400-500 mbs, upload at about 40-50 mbs. All was well until this problem, but its the first time I’ve had any problems and have been trialling ready for when I stop Plusnet, which is now extortionate.

    I’ve had a problem in Scarborough since yesterday evening. My 4G mobile broadband was running at dial up speeds on a Smarty SIM. It’s usually around 35mbps. Several restarts & a router relocation to another room finally got me back up to speed.

    Absolutely zilch signal here now at my office in GU6 8 on Three. Signal is not great at the best of times, but normally get something or fall back to wifi calling. Wifi calling not working either now – tried forcing it with flight mode on and wifi on, that didn’t make wifi calling work either.

    1. Avatar photo GH says:

      Could be an issue with packet-switched calling (i.e. 4G callling aka VoLTE and wifi calling). As I had a 4G signal after my initial post, but then my phone switched to 3G to make a call, and as I mentioned in my original post, wi-fi calling is still not working. Obviously packet based services would affect mobile data too.

    this issue is nothing like anything I’ve ever seen before.
    I can’t register to the network until I go to make a call… I dial 7777 and I suddenly go from No Service to full bars “iD” and the call connects. Soon as I hang up, nothing.

      thanks for that tip.

      dialling 7777 whilst the recorded message played I was able to divert my calls to my work phone on sky.

    Quite shocking. You can see why they’re the cheapest network.

    1. Avatar photo Richard Branston says:

      o2 had the same scale of outage a few years back – I seem to recall it was a change made by Ericsson (or similar) / the outsourced partner that was managing their network. Not necessarily to do with low-cost, not least as 3 are investing at a faster rate on 5g rollout than Vodafone or o2.

    2. Avatar photo Jim says:

      This isn’t a rare occurence with Three. The nationwide test for the emergency alert system also failed on their network.

      They’re just not a serious network, especially for higher spending business users.

      the Ericsson thing was a security certificate that had reached its expiry date, presumably somewhere inside O2’s core network, and it also took out Softbank in Japan at the same time

      Anyone with a Three number ported to another network may well be having issues due to the bonkers way UK porting works.

    3. Avatar photo John Smith says:

      Usually because people who are not of the impacted network (e.g. O2), who try to call somebody on the impacted network (Three), think the problem is because of O2. So they log it incorrectly (in this example O2).

    Bit intermittent here. But does appear to be affecting 4G mostly.

    Couldnt get my bus ticket to work this morning on my mobile, so had to pay again, thats the first thing that indicated a problem.
    5G Works fine, pushed my router at work to 3G so i could browse the internet without being snooped on by work.

    First time ive known 3 to have a problem, been with them years and not seen this before with them.

    Then I received an email in November saying we tried to ring you we tried to text you but got no reply so we closed you case down. During the time I got no signal for over a week so I didn’t get a phone call or text from them or any info regarding why it compensated. Now it’s gone off again 1 month to the day it came back on I’m now going to contact the ombudsman now and see if I can get my contract cancelled as they billed me when I didn’t get service for nearly 1/3 of a month but charged me regardless if they cannot provide a service then we must have right to cancel such service. During that time the status checker was working so I got a screen shot for most days it was off other than the weekend as had no one to contact so kect until the following Monday to log my complaint with them but to claim they called and texted me during the outage and closed my case was rather anoyying

    If the Gamma status notes are to be believed then it looks like it could be a single faulty device

    www . gamma.co.uk/support/service-status/

    Issued 01/12/2023 16:55

    3UK have an engineer awaiting delivery of the new device and will fit this as soon as delivered.

    A further update will be provided by 7PM

    Issued 01/12/2023 15:28

    3UK have identified a faulty device in their network causing intermittent disruption to service. They are working to replace this device with delivery to site anticipated by 19:00 and are reviewing what additional mitigation they can put in place to minimise disruption.

    A further update will be provided by 5.30PM. We thank you for your patience during this time

    Issued 01/12/2023 15:00

    Our mobile partner 3UK have observed an increase in 3G and 4G call failures due to an ongoing transport fault, which may also have some impact for data connectivity.

    Activities are currently underway to recover services which may result in customers encountering a brief disconnection from the network.

    A further update will be provided by 15:30pm

      that is a faulty piece of hardware that their vendor is replacing under break fix agreement.

      they should ideally have at least 2 of each critical item and have 2 different locations with identical kit in place so as to remove single points of failure.

      truly not a good look if a single faulty device has bought their infrastructure for the whole nation to its knees.

      weird that I can connect to 7777 just fine.

      maybe something related to their authorisation & accounting (the thing that says yes this customer can make that call and have credit balance to do so) platform

    2. Avatar photo Me says:

      Yeap, all it will have been is a major piece of equipment, router or something going pop. It happens, when you are talking about high throughput high end kit like that it costs thousands and is meant to be reliable, but it’s in 24/7 every single day components fail eventually. They’ll replace it with a spare and it’ll be up and running again.

  52. Avatar photo Rob says:

    I’ve been with them for less than 72 hours and noticed this from this afternoon, no signal, not connecting to the mast. Initially thought it was the phone, it might the usual level of service and then finally saw downdetector. Oh well 72 hours into my 24 month data only contract what fun!

  53. Avatar photo stuart says:

    mine dropped signal about hour ago. TBH the past two months the signal coming through and transmitting has not been good at all.
    am in the Wiltshire/Cotswold area and lately indoor calls are terrible. Even the wifi calling has dropped out (which have never had a problem with before) Three do need to keep better updates with this turning 3G network off.

    it is a minor inconvenience for me, it’s a good job wifi though has other means to contact people with these days, which seem far more reliable

    Total loss in central London. Went down around 3:30-4:00pm, absolutely nothing since then.

    Seems ridiculous that one piece of equipment can be so crucial to the entire service, and can be running without a backup ready to go.

    Not a good look for Three!

    1. Avatar photo Oldtimeuser says:

      EE was affected too, same as Three and O2.

      Just because you were not affected, it doesn’t mean another EE user wasn’t!

      Your comment doesn’t prove anything.

      I’ve got mobiles that use EE network too, I didn’t have any issues either, but as said above, we didn’t but other EE users did.

    2. Avatar photo Ivor says:

      are you sure you’re not seeing some localised EE issue (cell sites can fail from time to time) and assuming it must be related to the issues with 3 which are clearly more widespread?

      the only possible link is for users whose number originated from 3 and who had later moved to EE. Incoming calls (and I assume texts?) pass through 3 and a fault could conceivably affect this.

    Whilst engineering activity to change the effected card continues to be underway, 3UK have worked to mitigate impact through network management. We will continue to monitor the situation and a further update will be provided at 10AM tomorrow

    1. Avatar photo Strange says:

      If its just a faulty device within the network that is at fault, then how come some Three users in the same town and in the same exact location were not affected? Its very strange.

      Unless it didnt affect certain phones

    I’ve had no service since around 3pm until after 6pm in Bolton. My Dad and some of my friends all reported the same :/

  69. Avatar photo Monika says:

    What a joke, I live in the middle ofthe city and this small issue has been impacting me for the past 7 months now. I’ve contacted them multiple times and been told to wait a week, then to just wait one day. I’ve even raised a complaint because I got this for work and I’ve spent over £100 just to be using my mobile data anyway and all they did was take a tenner of 1 month’s bill and promised to upgrade the lines and that it would take a month. More than a month later the same issue still hasn’t changed a bit, I can’t work with it at all and I am ready to cancel. They make empty promises and don’t even compensate for their incompetence.

  70. Avatar photo Oldtimeuser says:

    Friday 1st Dec brought issues for those on networks of Three, O2 and EE, it wasn’t all related just to Three.

    However, Three seemed to be the ones having the most issues and problems fixing it, therefore they got the most attention during the day for it.

    1. Avatar photo Oldtimeuser says:

      As of 2nd December at 0030hrs, their website states:

      “A number of customers may be experiencing intermittent issues with our network. Data services have now been restored and our engineers are working to fully fix calls. We apologise for any inconvenience this has caused today.”

      Hopefully, it be back up over weekend for those still having issues.

      Just remember, if there are any cost occurred from this for anybody, then keep a written record with pics etc, as Three should reimburse you any costs associated.

      My SIM is still dead.. Not sure what planet they think it’s resolved..

  71. Avatar photo Martin Hinchliffe says:

    11 days in the tq3 area we have had virtually zero service with mostly phone displaying emergency calls only and sometimes no network , multiple support calls , each saying different things , seems they are doing some works however they said they had notified affected customers, well 12 members of extended family in 5 mile radius all same issues no notification.
    Last “chat with India based customer service they said 6 more days of this ” utterly crap service from three.

  72. Avatar photo Welcome2hell says:

    Im on Three but I didnt have network issues when others did. There were many people going into the 3 store complaining that there was no network. I was told its not affecting everyone. Then when I got home I had no signal for like 2 minutes.
    Have you seen the Three twitter feed? people are getting charged for no apparent reason. Also some customers are receiving a text stating something about ‘spend cap’ & £7 million or so charge. I wonder whats going on.

    This morning around 10.30 am until 8pm all my family couldn’t make a call or go online. We all use 3 network. Me I am taxi driver, I use the mobile to work I couldn’t go to work because of this an acceptable network. I lost my earnings. Is 3 gonna compensate me I don’t think so is not the first time this happens. I am leaving 3 network.

      If you’re operating a business that is reliant on a mobile signal then you really ought to have a backup network.

  77. Avatar photo Net says:

    Just an observation. I ran cellmapper app to see which masts Im connected to etc and I noticed my phone was connecting to a mast much further away than the usual one. I wonder if masts are being sorted/ rebooted/ whatever one by one. The phone battery is draining ultra fast too. Im guessing thats because the phone is trying to hunt for a signal.

    I think it has affected only some of my connections as my 5G broadband is working but then my sim on my phone has been off all day. I think they are doing some switching over of accounts from what I was told, from an older system and working on getting rid of 3G also. Let’s see eh.

      Got my son a 3 payg sim to travel to usa and back with data pack. The day he landed back in UK was the day network failed. He said ‘this network is horrific’ and promptly put his Vodafone based sim back in as soon as he got home.

      I think it is safe to say he will not be a 3 customer anytime soon!!

    4th December. Been off since 7:56 as per usual no issues according to 3. Who do they think they fooling since I went with them from march I’ve had dropouts every single day sometimes more than 12 in a day and lately for hours. What really bugs me is that they don’t let you know so you start thinking it’s other equipment that you’ve got and reset everything. Someone living on their own relying on their internet phone this is really becoming a problem and they don’t care. I’ve even sent in a letter of complaint contacted them so many times it’s unbelievable and still they’re not doing anything. Worried they’re going to become the largest ISP in the country and we get total gridlock.
