    @O2 I tried a browser but priority it kept saying I wasn't logged in. It never worked

  • Rochdale_Cowboy Craig (@Rochdale_Cowboy) reported from Maidenhead, England

    Took out an @O2 account as part of some 'volt' deal with @virginmedia. My god O2 are bad. Apparently you have to wait a few months to access your account online to wait until their systems "catch up" for new joiners. Shouldn't have bothered.

  • Stasisesque Lou 🐝 Lou (@Stasisesque) reported from London, England

    A tale of two CS agents. @O2 dealt with my issue and O2 Travel quickly and with excellent customer service. @Lustriga who has an IDENTICAL issue is being dismissed constantly and told it's his problem as the agent is refusing to read the conversation.

  • juliet_gough Juliet MacKenzie Gough (@juliet_gough) reported from London, England

    @O2 can I use my phone in Israel? I’m pay monthly customer.

  • MaryFaulkner68 Mary Faulkner (@MaryFaulkner68) reported from Wokingham, England

    @O2 your customer service needs looking at I contacted them at 7.40pm about an order,I went through security etc, then to be put on hold just before 8.00pm then to be cut off as you close at 8.00 can't contact again till tomorrow evening

  • electriccandles ⚡️Emma⚡️ (@electriccandles) reported from London, England

    @O2 I've tried all that already. If I had WiFi access I wouldn't need the data to work. Phone signal works fine, just can't use anything with Internet. It's been like this for at least a month.

  • RobertBalaam Robert Balaam (@RobertBalaam) reported from Southall, England

    @O2 I've tried twice. 45 minutes each time. Absolutely horrific service!!!!!

  • RobertBalaam Robert Balaam (@RobertBalaam) reported from Southall, England

    @O2 To not have a call-back service when calls are over 15 minutes is abhorrent 💩

  • Jennifer03017 Jennifer Ferguson (@Jennifer03017) reported from London, England

    @O2 when you press use now on the Priority Lane where is the code - I only have a screen with a timer counting down. I can’t see a code? Thank you xx

  • Indian_Thriller Jeetesh Luhar (@Indian_Thriller) reported from Iver Heath, England

    Hey @O2 how do I cancel a SIM card that @virginmedia sent me as a data roaming replacement for the lack of WiFi installation service they’ve provided me at my new property? I wasn’t expecting to be charged extra for this mess up on their side so it’s a no thanks from me.

  • chris_reed Chris Reed (@chris_reed) reported from Hillingdon, England

    @O2 any Ida how long your site will be down for? I want to get a bolt on that works for Turkey, and I’m just about to take off…any advice?

  • turningleftfor Turningleftforless (@turningleftfor) reported from Guildford, England

    @Dickster27 @ThreeUK @O2 Thanks for the tip! Very odd way to do things. May be useful for some but the coverage is awful on 3 at home too so I’m definitely off to O2.

  • Kierbro Kieran Brown #FRSA 🏴󠁧󠁢󠁳󠁣󠁴󠁿🇪🇺🏳️‍🌈 (@Kierbro) reported from London, England

    @tomlister @O2 @O2 reception in Bath is absolutely appalling. Had same issue all week long when was working at theatre there couple of weeks ago. Similar issue following week in Manchester.

  • ChatanG001 C (@ChatanG001) reported from Wokingham, England

    @O2 really shocking customer services today. All i want to do is pay off my device and it takes 3 people almost 45 minutes to even be able to do that!!! Stupid.

  • PowellVerity Verity Powell (@PowellVerity) reported from Spelthorne District, England

    @O2 will I get final bill? I’ve loved to another network and want to cancel direct debit

  • PowellVerity Verity Powell (@PowellVerity) reported from Spelthorne District, England

    @O2 worst customer services, ring 202 to pay off phone and they cut me off then don’t answer, told on chat to follow link to chat to someone else who tells me they can’t help and ring 202! Going round in circles no wonder once paid off phone I’m leaving!

  • Shaneyfirkins96 Shane (@Shaneyfirkins96) reported from London, England

    Is anyone else having issues accessing @O2 Priority Mobile App on the S23 Ultra... i haven't been able to access it since the s23 Phone's have Been Released

  • electriccandles ⚡️Emma⚡️ (@electriccandles) reported from London, England

    Idk what's going on with @O2 signal atm, but for the last few weeks I have no data signal around Crystal Palace at all. Doesn't come back till I get down to Sydenham. Weird

  • GhadeerAhmed96 Ghadeer Ahmed (@GhadeerAhmed96) reported from Ash, England

    Will never get a contract via @O2 . The worst customer service I have ever received . Shocking!

  • EmlynAD Emlyn Akoto-Dwemoh (@EmlynAD) reported from Esher, England

    @O2 Same network. PAYG to SIMO. I was told on the phone yesterday that it would take 3-4 hours. Not happy. 😔

  • lesleybphoto Lesley Burdett Photography (@lesleybphoto) reported

    @O2 Can we PM about a nuisance caller on your network please? He is calling women photographers around the UK and being inappropriate. He is well known to us and it needs to stop 😠

  • dawnypopssquad 💧 (AtT) | Dawnypops 💧 (@dawnypopssquad) reported

    @O2 My 4g is enabled I got a pop up message saying o2 have turned off 4g calling on your account and I’m at work and am thinking great paying for a half service now I will try what you suggest

  • mjnutley Martin (@mjnutley) reported

    Hello @o2 I’ve just ported my number across from ee and when I log into my o2 with username and password it says I don’t have any products and services, however when I sign in with mobile number I can view everything - data, minutes etc. can this be rectified please?

  • Katy_r01 Katy (@Katy_r01) reported

    @O2 my iPhones back camera lense has smashed, will this be covered by o2 accidental damage i pay every month? If so how long will it take to be fixed

  • doncmccall Don McCall (@doncmccall) reported

    @O2 Hi o2, interesting this. When I get an email from you to say ‘upgrade early on us’ the truth is you HIDE the remaining to pay in the next upgrade tariff. Very poor and lies. I have £36.70 left and over 36 months all tariffs are £1 a month more expensive. Deceit!

  • JuyeyDoodles JuyeyDoodles 🦇 (@JuyeyDoodles) reported

    @ajbaxter86 @O2 I have a USB adapter, but apparently they do new ones now but they don't sell it with the phone which is just rude, expecting you to pay more for the charger which you need to charge the device you've just spent loads on. Silly robbing companies. Thank you though 💙

  • mummycarys2010 Carys Lloyd (@mummycarys2010) reported

    I don't know why companies use @DPDgroup_news Terrible service. They have lost my new @O2 phone that should have been delivered on Wednesday and I only find out today because I have called them 3 times!! Takes 6 working days to investigate, I leave the country on 29/3 👍🏼

  • wendyg4073 wendyg4073 (@wendyg4073) reported from Kilmarnock, Scotland

    @nattystevenson1 @O2 Mines has been piss poor for a few weeks, vodaphone three are useless here so O2 were my go to but now I'm not so sure, glad it's not just me then

  • Kazorina Karen (@Kazorina) reported

    @O2 would love to speak to someone who A) does not sound like they’ve just woken up B) puts me on hold for ages until I give up or C) just hangs up on me! Service is disgusting, I need a long standing issue sorted! Will never consider o2 as a network again 🤬

  • elle_3113_elle Elle (@elle_3113_elle) reported

    @O2 so when you say order before midnight for next day delivery you mean order Thursday and receive your purchase whenever the hell they feel like sending it to you? Cos that sucks
