    @EE But was rubbish once I left the city and went home. Hence, I’m still with @O2 who I also got a 4G signal from in the city.

  • OllyFT Oliver Fytche-Taylor (@OllyFT) reported from Chadwell, England

    @iD_Mobile_UK @O2 @giffgaff As expected, and despite the promises, I have received no call back for a third (and now final) time. Please escalate the complaint as requested - I've had three commitments for a call back only for you to miss every single one of them. Beyond poor service.

  • HeyImMichaela Michaela (@HeyImMichaela) reported from Balderton, England

    @Oh_So_T @O2 I rang up but it wasn't very helpful. My signal is still poor. I have a months credit on my bill though now, so at least I'm not paying for it... Still doesn't help the frustration waiting for stuff to load!

    @O2 not impressed with service, offered an upgrade but downgraded to 3G ..... Spoken with 4 people, 4 different explanations but still not resolved. Would appreciate some action please

  • poshfrocks Penny Webster-Brown (@poshfrocks) reported

    @O2 No he’s not . He’s 90 and I manage his account. Managed to top up and then got a failed email. Customer service needs to be in UK.

  • Janet_West Janet Georgiou (@Janet_West) reported

    @BladesOli @tescomobile @O2 Tesco Mobile's service is based on O2's network.

  • pw0211 Paige (@pw0211) reported

    @O2 Nope says connection problem or invalid MMI code.

  • Ashlea_K Ashlea Kattenhorn (@Ashlea_K) reported

    @O2 I don’t have a spare phone to try it in no, my won’t have signal or 4g literally doesn’t work anywhere

  • matthewmurray90 Matthew Murray (@matthewmurray90) reported

    @O2 customer service is shocking! Been hung up on twice now when simply trying to change direct debit date! Absolutely shocking, have 5 contracts with yourselves and going to move them all to @VodafoneUK when they are due for upgrade!

  • ChrisEddy_7 Eddy 🏴󠁧󠁢󠁷󠁬󠁳󠁿 (@ChrisEddy_7) reported

    @sammypenrose23 @O2 I can’t even get o2 to email me back about a complaint end of January and people are receiving these boxes 😢😢😢

  • chillkhupe Chill (@chillkhupe) reported

    @tiny_mischief @O2 Add to that when your contract is up and you move to monthly contracts only all of a sudden the connectivity to 4G is constantly at 1 bar and data runs out extremely quickly @O2 I never believed this happens but it is. Wry disappointing. Moving very soon.

  • Steve_Red_Beard Red Steve (@Steve_Red_Beard) reported

    @GrantRustique @O2 I will try a full system wipe , then move my O2 physical SIM to esim again , then that frees up the SIM tray for my EE physical SIM , then at least I've got a fresh system as well as both Sims active in case one has a yawn and slows down or drops connection.

    @O2 Unfortunately that guide does nothing to improve my speed or service
