    @virginmedia Thanks. Can you confirm that as virgin and @O2 have joined together, will a virgin SIM card work in another phone that uses O2 SIM cards? In the phone it would be used in for a month is a phone from O2 but using a Tesco SIM, which uses O2 network. I think virgin SIM might work?

  • yasmine_al Yasmine Alina (@yasmine_al) reported

    @O2 I need to mention that I am alone here, no one to help, the lack of phone number is blocking my access to bank accounts and other online accounts. O2 managed to make me feel completely unsafe. I've lost trust in advisors considering I've been misinformed for 3 consecutive days.

    @O2 customer services truly are as much use as an ashtray on a motorbike.

    @VodafoneUK A customer for circa 25 years and I’m on chat to cancel all contracts! After a difficult upgrade process I’ve been left with a new phone and no number for 1 week. Happy to talk through if anyone cares. #customerservice #FAIL going to @O2
