  • StvnMhd Steven Mahood (@StvnMhd) reported

    @O2 the signal in my area has been terrible for months now. Full 4G signal but nothing loads, messages can’t send. What can I do?? Without Wi-Fi my phone is useless.

    @O2 In solidarity with Iranian people and in support of their uprising wondering if O2 is willing to make SMS and Voice to Iran free of charge. #IranProtests2022 #Mahsa_Amini

  • YeoZowie Zowie Yeo (@YeoZowie) reported

    @O2 when you ring an ex customer to resolve an issue but then hang up? This a way of you calling to say your tried to contact the customer and let it ring twice? And mark on the system as called the customer?? Really bad customer service….

    @MacchinaMedia @O2 @EE I had EE and it was terrible where I stay in Cheshire and the WiFi calling through my Bt router wasn’t much better,

  • alex_nelu Alex Nelu (@alex_nelu) reported

    @Kwig1 @virginmedia @O2 I would recommend moving to a different network, which is what I’m going to do. I was on Sky Mobile before and it was decent service, and in theory O2 was supposed to be better, but it’s just pathetic. It loses service even though it’s still showing 5 lines of 4G.

    Hi @O2 I am struggling to get my voicemail to work..it keeps saying "could not be set up as not received your number"....can you help please?

  • rhianna_joseph Rhianna Joseph #PrayForDemi ❤️ (@rhianna_joseph) reported

    @O2 you still haven’t responded to my DM. If you don’t respond at all will disconnect my account and will lose a customer.
