    All of this on top of the a fact I’m paying contract with @O2 , still 3 months left to go and I’m left without a phone! I swear I am never buying mobile insurance or a contract ever again. ******* livid.

  • SqueakySays Squeaky (@SqueakySays) reported

    Hello @O2 any suggestions please on how to get my new phone & contract activated? I’ve been waiting since Thurs - doing it online doesn’t work as apparently it’s ‘complex’ and I have called you twice, both times advised it’s in progress, however NOTHING has happened. Help!

  • jammergilmore James Gilmore (@jammergilmore) reported

    @O2 Thanks but I’ve had a mobile for 30 years so know how it works and all the tricks .. I’m turning my phone off and on again daily, and turning data off and on again … full signal bars and 4g and it still barely loads anything … it says 3g more than 4g these days

    @O2 I got a new phone yesterday and opted to keep my old number. I was given a new sim but it’s set up for a different number! Can someone help?

  • ludast22 Luka (@ludast22) reported

  • Vicbel76 Victoria Carson (@Vicbel76) reported

    @O2 network down since Sunday and can’t get through to anyone. Can you help please.

  • Em_The_PM Emily Hannon-Luijbregts (@Em_The_PM) reported

    @O2 : I've received a letter for a previous occupant of my house. How can I inform you that they no longer live here? As I'm not the account holder nor do I have a forwarding address. Can you help please?

    @O2 @jammergilmore 4G in and around Bristol is awful...major city...not good enough

  • cursednumber7 Stu (@cursednumber7) reported

    Hi again @O2 I now cannot send text messages on your terrible network. My phone reckons I’ve got a strong 4G signal, little does it know that that means nothing on O2
