    @O2 I’ve had problems receiving and sending texts over the last few days. Apparently there is a problem with a mast. Do you compensate customers for this as I am paying £32 a month for the tariff.

    @O2 I was so excited to receive the Disney+ free months free text as a thank you to me for being a valued customer just to then be told when I went to claim for it that I am not eligible for it with no explanation as to why.

  • PeterClaydon Peter Claydon (@PeterClaydon) reported

    Hmmm. I'm on the @O2 network in the @TheO2 and my #5G phone is on 4G. It started off on 5G.

  • TaiKamiya101 Tai Kamiya 🇪🇺 (@TaiKamiya101) reported

    @WhatsApp How do you change your number but only allow certain people to be allowed to have it? I pretty much want to prevent some people from knowing that I have changed my number more or less. @o2 can you help on this otherwise?
