  • adammccalden Adam McCalden (@adammccalden) reported from Belfast, Northern Ireland

    @virginmedia since my virgin mobile UK signal has been shifted from piggyback Vodafone to @O2 it has been a complete disaster, constant signal dropping, constant WiFi calling cutting. This is before my account has been transferred to O2. Complete and utter rubbish

  • MrsZouZou Zoё Pritchard (@MrsZouZou) reported from Donaghcloney, Northern Ireland

    .@O2 sitting in a power cut, but at least I have full 4G signal…. Despite what my phone shows, nothing is updating and have been forced to hotspot off my husband’s EE signal… not your finest hour!

  • TheRealJackieJ Jackie Johnston (@TheRealJackieJ) reported from Castlereagh, Northern Ireland

    @O2 Thanks. How do we unsubscribe from this ****? We pay for 5 contracts and do not wish to receive these messages particularly on children’s phones.

    @O2 Customer services. A Google Pixel 4. No reference number. I've had to call them myselves today and nothing has been done to resolve this. Was told I'd get written confirmation I'd receive a call back. Still nothing.

  • MariseWilden Sarah (@MariseWilden) reported

    @O2 I am able to login after re-registering with the same email address this morning on the website. This is the email I used to buy our contracts but it says no products associated with this account.

  • DiLussoMenswear dilussoclothinguk (@DiLussoMenswear) reported

  • Priesty_Tom Tom_Priest97 (@Priesty_Tom) reported

    @O2 I am having trouble trying to get service on my phone and have had to use my old sim which had two months left on its contract since I upgraded in Feb, I put my new sim in again today as the other contract has now ran out and I’m still getting no service, please help! 🥴

  • Nathdanbrown Nathan Brown (@Nathdanbrown) reported

    @O2 Disgusting customer service. Advertise an extra £200 trade in deal and then don't fulfil it, my model of phone conveniently disappears from the portfolio once I get my new phone. Call Thursday "you'll get a call back by Saturday". Nothing. Ring Monday. No clue. Raging.

  • grshorwich Godwin Stewart (@grshorwich) reported

    @psychomania666 @O2 Makes you wonder... If the MVNO can get SMS/Wi-Fi working, how come the network owner can't? Methinks they don't *want* to get it working for some reason.
