    @BradyHaran @O2 One time I disabled Airplane mode while flying over Canada, I somehow managed to get some cell service and realized that when I received a text message saying my bill was reaching 80€

  • sarahbennetto Sarah Bennetto: a comedian of sorts. (@sarahbennetto) reported from Fingal County, Leinster

    @O2 hi guys. My phone stopped working in Europe (since I added an Aussie E-sim). No one in your O2 UK shops can help. I even deleted the E-sim. But still: no roaming. O2 said I should wait until I’m in Europe for work again and call you (I can’t; that’s the point!). Help me, pls?

  • skbarrone Sarah Barron (@skbarrone) reported from Fingal County, Leinster

    @O2 Thanks. Problem started in London but same in Dublin. Everything works fine on Wi-Fi.

    Can't help thinking @O2 have really ****** up with these yearly price rises. Remember when @ThreeUK kicked everyone off the One Plan, it took them several years to get the lost business back. But hey they know best. Bet PAC codes are flying out the door today.

  • lilgamerman LilGamerMan | GameOn (@lilgamerman) reported

    @O2 cant pay my bill through app. Cant contact customer service through app. You cut my service until bill paid. Help this a utter pisstake

  • jayneyd83 Jayne Robinson 💙 (@jayneyd83) reported

    Hmm @o2- mid cancelling my contract and your website seems to have now ‘gone down’ 🤔 #rubbish

  • HughesDigital Kevin Hughes 🎥 (@HughesDigital) reported

    @Ofcom The only scams are when companies like @O2 put their prices up mid-contract. How about clamping down on that @Ofcom? You are not fit for purpose, I feel internet and mobile companies are scamming consumers every April and you do nothing to protect us from these unnecessary hikes

  • qlexroby qlexroby (@qlexroby) reported

    @O2 what’s going on with my data you *****. 5G 4 bars but doesn’t work sometimes? Then you have the cheek to send me an email about prices increasing. **** you. *****

  • fozzer007 Andrew Forster (Fozzer) Adidas Addict (@fozzer007) reported

    .@O2 absolutely rubbish this network provider, I've been with you for 20 years and I'll be moving unless you sort my mailbox issue asap

  • WoodpeckerMandP Blueflyer (@WoodpeckerMandP) reported

    @O2 Do you not care at all about customer service, twice I’ve called you now due to fraud, my account is still hacked, I can’t use my iPad and monies still being used on my account. How can someone get an eSIM with out any security form O2, disgrace and you still won’t help me.

  • ross003ross Ross Southgate (@ross003ross) reported

    @MartinSLewis @GMB Ive been an O2 customer for years, now on sim only and after this news I'll certainly be looking for cheaper sim only deals elsewhere. Goodbye @O2

  • AHunter1604 Just A (@AHunter1604) reported

    @O2 why has the slow network in my area still not been resolved? Been fine since I became a customer and suddenly dropped out over the last week. The message on the service status about “busy area” is a poor excuse. It’s like using 3G again.

  • BarrettsFitness Graham Barrett (@BarrettsFitness) reported

    Have @O2 purposely shut their website down to stop people leaving their contracts or has it crashed due the amount trying to cancel #timeforchange
