O2 signal strength problems hit UK

By Updated on

Millions of UK phone owners have woke up this morning and turned on their phones as normal, but thousands of O2 users are finding signal strength problems on a range of devices. We have two iPhone 4S phones running O2 in our UK office, and both have problems gaining more than one signal bar and cannot send or receive text messages or make phone calls, which shows either the O2 network has crashed or there is an issue with cell towers.

Some of our readers might have seen a few people complain about O2’s network over the last few days, but thought nothing of it until this morning when a much wider issue has taken place. Conspiracy theorists will point out the Sun erupted with its biggest solar flare yet (X1.1-class) for 2012, which happened on Friday and could have caused problems with satellites O2 are using, although we think there is a much more logical conclusion.

You can see an iPhone screenshot taken just a few moments ago running on O2 in the UK, and as you can see there are no bars. This is the first time we’ve seen this from O2, especially considering the phone had been restarted several times over the last hour and still nothing. The second phone we tested also has this problem, and we managed to speak with one other business contact in the UK and they too have problems with O2.

Online reports suggest that the O2 network crashed yesterday, and O2 has responded by explaining the issue is not related to hackers. Officials have also stated that not all of O2’s 23m users are affected, but considering how widespread we’ve found the issue to be it would be good to hear from our UK readers.

How is your phone this morning if you are on O2, can you send text messages and receive phone calls? Is this an issue just related to iPhone users, if not what phone are you using? In the last few moments we heard from O2, and they said engineering teams are trying to fix the issue right now.

    This was nothing to do with signal strength. O2 accidentally locked out a whole range of IMEI codes after a network upgrade. For example, of the 3 O2 blackberries in our house, all the same model, 2 were working fine, and the other was completely unusable.

    Since the solar flare, I can fire lazers from my iphone

  • Cheema

    Ok. It’s 3rd day and I don’t seem to have any signal if I turn 3G on. I m going somewhere and needed google maps but looks like its not going to happen. I switched the phone off and back on few times but it doesn’t work. Only works if I disable 3G :-(

  • Bonnie

    Hi there.
    Adding to your poll: No signal at all since yesterday 2pm,no txts,no calls,no data. East Londoner,with Blackberry on full contract from O2.

  • Steve

    I have an iphone 4S and have just been told to disable the 3g. After doing this I have found that this has altered my signal strength to nearly full bars. Hope this helps!

  • Madcaddie_1

    iPhone 4s Somerset. 3 bars of signal but sending and recovering texts and phone calls as normal.

  • Sophie

    I’m from Durham and my iphone signal seems to be fine. I have 4 bars of 3G and managed to send a text, have the problems stopped?

  • Karl Ascroft

    I have an iPhone 4S, I’m based in Cheshire.  My phone lost it’s signal and 3G yesterday at 1:30pm.  When I woke up this morning, it had been restored.  I was the only one in my office to have this problem yesterday, but today it seems as though it is their phones not working now, whereas mine is.

  • deli

    This morning it wouldn’t work, but it seems to be completely fine for me now.

  • Will

    Had a phonecall no problems this morning, and now nothing. A minute of full signal appears out of nowhere, then disappears just as fast. iPhone 4S in Gloucester, for reference.

  • Chelle93x

    Yesterday day I had no signal from about 3pm? Woke up this morning and have my phone is completely back to normal! :) Inverness, Scotland

  • Sofia

    Haven’t had signal since around 7pm last night… Only just this morning the O2 name appeared back up at the top of my phone with no bars. I thought it was just my phone – never a time where I haven’t had problems with the thing!

  • Johnamthomson

    I have an Iphone 4S in London. Texts are fine but can’t make calls since last night. Rebooting or switching off 3G doesn’t help.

  • Samueljwhite

    iPhone 4s on O2 from Ashford, Kent. No signal as of this morning.

  • Simobo

    Simon, Derby

    Had full signal this morning, went to send a text and it failed. Signal completely dropped and I cannot send or receive calls or texts now.

  • Rob

    And people said 3’s coverage was bad pfft… Mines got full signal.

  • Mel

    I suggest you all call O2, when your signals back and demand a discount on your bills for the inconvenience, if you’re adament you want this discount or you’ll take it to their managers and maybe even find a better network, they will give in.
    I left them for Vodafone and although they’re not perfect, I’ve had more than a months worth of bills wiped because I’ve had momentary signal problems or my battery wasn’t lasting so I couldn’t use it off charge.

    • Pegman

      i agree, this proves to me that it is to to with network upgrade problems as i am on tesco with an iphone 4s and repeatedly(even as now)i frequently try to send text messages and it fails, i have to resend several times before it goes through. i did not complain to tesco(yet)and they sent me a message saying they would give me a goodwill gesture as a result of the network problems. tesco mobile of course use the o2 network!

  • Christianos

    Am in London.  I never get signal between about 2pm and 6pm anyway (my bars appear full but if anyone rings me it goes straight to voicemail and no texts arrive until 6pm, at which point they all arrive in a large cluster).  I’ve switched handsets and the problem persists.  

    But last night I lost signal altogether, with no bars on my screen, and there’s still no sign of it returning today.

  • Nikkitabahia1991

    Im from dudley.
    My phone went yesterday at 1pm. I rang O2 as I thought it was just me they explained they didn’t know what’s happened. May people are losing out on business and their plan for the days ruined (not really safe to go out without a working phone never know what the day could bring) I was stuck the whole day I connected to the wifi in the house as my 3g went as well and communicated to friends through what’s app, woke up this morning to a text but signal keeps coming and going. Everyone else in my house on o2 have signal. They need to fix up.

    • Richie1979

      Wow how pathetic. Can any one remember 20 Years ago when there were not any mobile phone at all. You went out and if you needed help you used a pay phone.

      Please people get a life and get I over it.

      • Janebrown89

        No need to be rude about it and there not that many pay phones around, p.s turn 3G and it works

      • Ryan1987
