    @O2 I need to escalate a complaint re. a member of staff who refuses to to 1) process my upgrade and 2) who has just terminated my call. Who can I talk to? Your staff say it’s not possible to talk to a manager.

O2 Issues Reports

Latest outage, problems and issue reports in social media:

  • RabbaGnosis Rabba (@RabbaGnosis) reported

    @O2 How can you access the network checker if the network is down? I know you've had your ceiling ripped off but presumably your masts are all standing. Terrible reception today, is this due to overdemand, just no way of telling.

  • returnmaia 🎄 maia (@returnmaia) reported

    @RabbaGnosis @O2 The issue is that due to the power outages, masts are forced to rely on battery backups, which only last a few hours at most, causing loss of connection

  • rubyannelines RUBES 😁🌈 (@rubyannelines) reported

    @O2 I’ve purchased a new phone from you and had an extra of free Apple Music. The link you’ve sent me won’t work. 😩 #Help

  • orlagh_murphy Orlagh murphy (@orlagh_murphy) reported

    @O2 Is there a problem with o2?? My phone keeps saying I have no SIM card registered but I do??

  • kingpak93 Paul King (Kingy) (@kingpak93) reported from Glossop, England

    @O2 Have changed phones and need a micro sim card. Have PAYG with credit so want to keep same number and credit I have. Ordered a sim card online a week ago and nothing has arrived. Can you help please? New phone sat unused as can’t put standard size sim card in it.

  • nickeady Nick Eady (@nickeady) reported

    Hi @O2 I logged a call in April 2021 reporting no signal in CM144HN. Since then I have been getting regular auto texts advising you are working on it. Can you please give a real update as the problem remains.

  • kingpak93 Paul King (Kingy) (@kingpak93) reported

    @O2 Thanks for the info. Yes I did get email but no sim. If I pick a sim up can I get that switched for the one I have to keep my number and credit? Thanks for your help.

  • MarkCatlin4 Маrk Catlin (@MarkCatlin4) reported

    @O2 FYI I got a call from this number (01242306032) claiming they're from @O2, apparently I've qualified for 30% discount on monthly bill. Considering I'm on Tesco mobile pay as you go I found it to be suspicious, when challenged person said sorry to bother & put phone down.

  • ashtonkooltchxr Ash (@ashtonkooltchxr) reported

    @O2 Yeah it says there’s a fault with the mast for the postcode I’m in but not what’s wrong and when it’ll be fixed so it’s very slow and dodgy rn

  • molimo3 Alex Molina (@molimo3) reported

    What’s going on with the signal at @EDI_Airport @O2. There’s bars but no data!
