  • silentobsello mamon (@silentobsello) reported

    Zero phone signal in G1 Glasgow today since 7 in the morning. And @O2 is falsely claiming that the issue has been resolved 😞

  • dmra199782063 dmra1997 (@dmra199782063) reported

    @O2 care to explain why you’re service is so terrible? I’d be faster lighting the beacons of Gondor than trying to send a message over your 4G service.

  • Incisive1 Incisive (@Incisive1) reported

    Erm. @O2 it would be helpful if you made a statement about your network currently notwork ing… number not recognised is crazy. Over 24 hours now. Smh

  • UgEvans Mark Evans (@UgEvans) reported

    @O2 why has my phone had no signal for over 24hr now. CS keep telling me if will be fixed soon and then nothing 😭

  • 84Worthy Worthy-84 (@84Worthy) reported

    @O2 Your missing the point. It's not about my postcode it's about the terrible service all over NW England from Chester up to Lancaster, Blackpool across to Manchester

  • RyxnPxe Ryan Naidoo (@RyxnPxe) reported

    @O2 Spent 30 minutes on the phone to them and the payment failed on their system as well. Tried several cards. Been a customer for years but now likely I’ll cancel and move to another provider. Making this far too difficult

  • craniosurgeon Christian Duncan (@craniosurgeon) reported

    @JamiePinner @O2 @rw_83 Ditto. Wife’s phone on O2 is fine-I get no signal/mobile WiFi anywhere.

  • LittleMissBake LittleMissBakes (@LittleMissBake) reported

    @O2 how much longer is this issue going to take? I can’t use my phone for calls/ data/ text messages. This isn’t good

  • ChrisLincoln80 #HelloMyNameIs Chris 🇬🇧 💙 (@ChrisLincoln80) reported

    @JamiePinner @O2 My phone often shows 3/4/5G signal but apps don’t work And then have issues joining WiFi

  • craniosurgeon Christian Duncan (@craniosurgeon) reported

    @JamiePinner @O2 @rw_83 Still no O2 signal and I can’t access my account because I can’t receive text!! Beginning to think there’s an issue with the SIM card or associated account.
