    Hi @O2 My mrs & I recently upgraded our phones (Iphone 11 > 14 & Samsung 21 > 22+) .. Ever since we upgraded we have both had real problems with signal in areas we both used to have no issues with at all including our house. Any ideas as to why? Thankyou

  • Sam_J_Griffin Sam Griffin Radio (@Sam_J_Griffin) reported

    @O2 why can I not connect to my voicemail? Keeps just ending it, even though I have one! Need to access it for work and it's getting a bit frustrating. Tried powering off, walking around in different areas.. help please!

    @O2 I purposely didn’t try to redeem it until I got to the restaurant. We spent half an hour trying to get it to work. £15 may not be a lot to you but it is to us - your offer meant we could afford to treat our children but we ended up having to pay almost twice as much as planned.

    @O2 Hi, my email was set up wrong when I recently joined o2 so I can't reset my login or access "MyO2". When I try to get help it directs me to "MyO2" but I can't login so I get stuck in a loop. Can someone help me out?

    @MartinSLewis @MoneySavingExp Fradulent @o2 account flagging on credit check so mortgage turned down unless we get letter from o2 explaining this. No joy despite repeated calls/emails for 3 weeks, have to move out in 2 weeks. Homeless with a 9mth old if not sorted. Any advice?

    @tescomobile @O2 signal/connection seems to be horrendous in CH48. Anything I can do to sort this?
