  • CraigFamilyBlog Hayley & Gavin (@CraigFamilyBlog) reported from St Albans, England

    Gav and I have had no mobile phone service for 3 days, but I have no service to call @virginmedia to let them know! It happens far too regularly. Just spent the morning searching for a new deal. @O2 looks like the best so far!

  • jmcomms Jonathan Morris 📱📸 (@jmcomms) reported from London Colney, England

    @VModifiedMind @benwood @EE @VodafoneUK @ThreeUK @O2 Albeit using half rate codec for voice. Sounded pretty awful.

  • DimitthriV Dimitthri Vithanage (@DimitthriV) reported from London Colney, England

  • 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!

  • 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.

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

    every single day your service going down ,moved to O2 from 3 , paying more getting less as compare to 3 but your service is kind of same , most of the places it just disappears, call failed, hardly one bar most of the time and no service at certain places.. v disappointing @O2

  • LydiaElenaxo Λυδια-Έλενα (@LydiaElenaxo) reported from Tottenham, England

    After 11 years with @O2 they are really trying my patience today.. I’ve been a loyal customer and honestly upgrading has been horrendous with you.. I think @EE might be my new home from today

  • AndrewTRIrwin Andrew Irwin (@AndrewTRIrwin) reported from London Colney, England

    @EmmaShubrook @O2 Agreed. I have no signal at all

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

  • ItsMeEllisxD Ellis Brown (@ItsMeEllisxD) reported from London Colney, England

    @O2 Well it’s every time I leave Leicester. Or go to a new city.. even when I have 4 bars it’s either really slow or won’t load at all!

  • 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

    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.

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

    @HowardGriffiths @O2 remember few months back when @o2 was down for nearly 2 days.. after that it’s service is going down everyday.. sometime when you are travelling and passing from certain areas O2 service will simply shift to 3G form 4g and sometime it will be No Serive at all 1/2

  • 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

  • Craigcanfield Craig Canfield (@Craigcanfield) reported from Welwyn Garden City, England

    @O2 contract finished.. put on a rolling month deal.. nothing will change they said... 2 days now with no phone signal.. "sim provisioned"! Customer svc say it'll work soon. Gggrrr

  • bryndows Bryndows Vista (@bryndows) reported

  • PabIotommo ᴘᴀʙʟᴏ (@PabIotommo) reported

    Your signal is ******* dreadful @O2 My EE pay as you go is miles quicker than this contract.

  • seraphin1971 Sarah Clayton (@seraphin1971) reported

    @dondon_kent @O2 I very much doubt it, 16 years with 02 and no loyalty to customer very sad

  • Berniedoggy Berniedoggy (@Berniedoggy) reported

    When do I get my little blue robot as an @O2 customer?

  • DavidUKEU David Clarke (@DavidUKEU) reported

    @O2 @EmGennn Same issue with me. Tried restarting phone but cannot enable wifi/4G calling and just get a message to contact O2. Started yesterday.

  • ryanegan2 Regan (@ryanegan2) reported

    @tomclark54321 @O2 Calm down mate

  • Jim_Trinca Deep Space Nine Enjoyer (@Jim_Trinca) reported

    @O2 I've cancelled it, tbh with a bit of thinking distance I'm not even sure I'll reorder. Thanks for your help anyway

  • Robbielane__ Robbie lane (@Robbielane__) reported

    @O2 not to mention the store only picked up the phone after the 4th time I had rang.. I started calling at 5pm. Because of the customer service we had received it’s tempting to cancel our order and go with another provider.. both 3 and Vodafone were both open past 5:30pm

  • Su__H Su (@Su__H) reported

    Wow. @VodafoneUK. You really tested my patience this week and have now lost a very loyal customer. Hello @O2!
