  • Macgregor11 Glenn macgregor (@Macgregor11) reported from Harrow Weald, England

    @O2 What's the situation for those of us that have recently taken a contract out with you with you supplying a Huawei device. Increasingly potentially losing all support for the phone now

  • johnsheppard71 John Sheppard (@johnsheppard71) reported from Chalfont Saint Peter, England

    @O2 I am an o2 customer for over 20 years ,I am not happy that I am due for an update and you cannot compete with other companies. Where is the loyalty to your customers .

  • Greekphotoguy Dimitris A. (@Greekphotoguy) reported from Tottenham, England

    @LuzDLuna @O2 When I got to the shop to collect the phone and was denied, since a driving license valid across Europe wasn't good enough, I was told the "there are procedures and cameras" and the staff couldn't help because they would get in trouble!

  • usmanyounas0011 Usman Younas (@usmanyounas0011) reported from Walthamstow, England

    @HowardGriffiths @O2 and if you are on call your call will be dropped(call failed)then it will take sometime fr service to start working again.. 2ndly most of the places getting only 1bar and very slow data browsing.. 3rdly when it connects to 3G it’s same like No Service it goes sooooooo slow 2/2

  • OmarMansoor Omar Mansoor (@OmarMansoor) reported from London Colney, England

    @Ali_Malik @O2 @Ofcom @MarkEvansO2 I’ll give them a #Valentine chance - never had issues before but now only on crucial days they go down. #

  • Greekphotoguy Dimitris A. (@Greekphotoguy) reported from Tottenham, England

    Dear @O2, I've been with you for years. Just upgraded for 3 years. But the fact that I can't take my phone because my European driving license is not acceptable ID is very annoying. It has my photo and name on it. My passport has the same photo! I really don't see the problem.

  • aktyrrell Andy Tyrrell (@aktyrrell) reported from Walthamstow, England

    @harwood_steve @O2 @EE EE service is shit around Chingford guys I work with never get a service I'm o2 never had a problem. Probably the country you're in. Plus we always get upgraded at the o2 by the o2 Angel's.

  • dlorimer93 Danielle Lorimer (@dlorimer93) reported

    @O2 So o2 staff have time to post stupid emojis but cant sort out when someone is committing fraud with one of your customers accounts. Complete joke

  • Matthew_Wood85 Matthew (@Matthew_Wood85) reported

    @socoedjones @O2 Over this past week I've struggled to get decent signal at work. Nothing at work had changed, yet the signal is crap 😔

  • mrgazlatico Gareth (@mrgazlatico) reported

    @Matthew_Wood85 @O2 I'm having calls just drop out after 1min and 6 seconds! Everytime only happened today @O2 any issues with networks in Leeds area?

  • itskyleflamson Kyle F (@itskyleflamson) reported

    Having to tether to my @O2 #hotspot again because #VirginMedia is unreliable, and unstable. I'd advise anyone looking to sign up to this ISP to find some other provider because Virgin will **** you over and lie to you.

  • InMiksWorld MiK (@InMiksWorld) reported

    @O2 why do you charge more for AIRTIME when you choose a larger storage device ? £22 for 64GB iPhone 12 mini and then £26 for a 256 version ?? 202 couldn’t help and Customer service just dumps the call - this increase also applies to Android phones too…
