    @O2 Hi, it’s been 2 weeks since i started receiving non stop calls from your call centres to get me get a plan with you, the caller said that i entered some kind of contest or signed up for this but i never did since i am happy with my current provider. This is very inconvenient

  • AlanGreene73 Alan Greene (@AlanGreene73) reported from London, England

    @StudiniJones @timlukejones @O2 Yep I thought the 13.3.2 update had fixed it but I’ve lost signal again this morning. Had to reboot my phone. I’m on latest update. Pissing me off now. People can’t call or message me until I’ve realised and turned phone off&on

    @O2 does anyone ever actually win. Been doing every priority competition for 2 years and never win a single thing

  • Link2076 LinkoVitch (@Link2076) reported

    How come I get messages from @O2 telling me there is work in my area to improve service, and now I get a text from them telling me using WiFi for calls may be better quality... So pay for a service but don't use it is the message I guess?

  • char_charmed 💥🧙‍♀️🔮ForeverCharmed🔮🧙‍♀️💥 (@char_charmed) reported

    I swear to god i won't be paying my @O2 bill this month if they don't sort out their network!..

  • Mabbannerman Martin Bannerman (@Mabbannerman) reported

    @O2 Nope, pretty much everywhere now. So frustrating buyt it's not just me, people I'm with now on O2 also can't access data despite having "full signal" and apparent 4G. Right now I'm in Leicester City centre!

  • AnnaLambertini Miss Lambert MCCT (@AnnaLambertini) reported

    @O2 Got a new phone. Neither old or new sim work in the phone. HELP! Can’t call for support. What should I do?
