    @O2 looks like my SIM card has been deactivated. I’m not able to talk to someone on the app or over the phone! Please help

  • timefried Travis (@timefried) reported

    @O2 @SmugFaceKevin How about you sort your service out instead these lame tips. Absolutely dreadful coverage

  • Abbie_SK A B S (@Abbie_SK) reported

    @O2 is coverage down all over the country? Signal is awful in my home town, drove to see family 3 hours away and signal is bad there, in london today signal is also bad. Can’t load google maps, Facebook, Instagram etc. I ALWAYS have to find wifi to connect to, can’t rely on 4/5g

  • sammilovemango Sammi (@sammilovemango) reported

    @O2 the mast has been down at my work place for over a month now, not being able to make any work calls! Disappointing to say the least, glad I'm personally not on the service

  • KittykatClaire Claire B🐈‍⬛🐈‍⬛ (@KittykatClaire) reported from Willenhall, England

    That, @O2 had better coverage now I'm left with all this extra stress when I'm out because my mobile doesn't work when using @O2 network.... Its not my mobile either. I have a Samsung s20.....

  • Whats_UpWithU Paul (@Whats_UpWithU) reported

    Quit @O2 as been trying to set up a phone for my son and constantly get a message ‘oops something went wrong’. So buying @Vodacom sim tomorrow and cancelling my contract also and switching over. Called 02 currently 30 min + wait. Bad service = 2 lost customers.

  • linkinparktom TomBSC87 (@linkinparktom) reported

    The worse thing is I’m stuck on another contract with @O2 thanks to the deal I have with @virginmedia - if I could I’d cancel that one too. Never again.

  • AssosChelt Daniel McGiff (@AssosChelt) reported

    When issue flagged here asks you to DM. Takes 36 hours to ask for an order no. Meantime you call them and get told order is still undergoing checks and you'll have an email by end of day. CONT @O2

  • Mamamatician Natalie Godwin 🐝 (@Mamamatician) reported

    I really don't like paying an expensive phone contract when I have the worse @O2 signal ever. O2 has always been amazing, now in the last month I'm lucky to have internet more than I don't. How can technology advance but something like signal decline??

  • _kou42_ Andy (@_kou42_) reported

    @O2 I cannot make calls while abroad. Texts and data work fine. Could anyone help me please.
