    @O2 Yes it’s all up to date. Still not working!! It’s only happening when it’s on charge. I’ve sent a DM explaining in greater detail

  • NathFerguson Nath (@NathFerguson) reported

    @jan2086 @ThreeUK @O2 Exactly I’ve got non existent signal in my town centre and after numerous complaints they don’t seem to care to fix it and now when I complain they just ignore the complaint. They charge enough so they can fix the issue they just choose not to.

    @O2 Hello, I have switched from android to iphone13 sim only and kept the same sim. I find my 3G and 4G to be quite poor and I have read that idata needs to be added to my SIM card? Can you help me please, thank you.

  • AngelaW1406 Angela Walker (@AngelaW1406) reported

    1/2 @O2 please explain why there is no supervisor to speak to when calling to complain? Issue after issue,being told different things every time we call.This could have been resolved 2 weeks ago but still outstanding & going away at the weekend so need assistance asap!

    @O2 @Bekhboyle O2 service is absolutely awful. There is no customer service. I have an issue with the mobile date on my Apple Watch for more than 5 days and they just passed me to O2 store, customer service, teach support team and … but they are completely irresponsible and just lying

  • herbs468 Lisa Herbert ♡ (@herbs468) reported

    @O2 why is the O2 signal so awful

  • odyssey_yety llannigan page (@odyssey_yety) reported

    Hay @O2 is there a reason that Internet has been getting slower for the last few years now to the point it is almost unusable even though you say your improving your 4g signal and have put up a new mast near me that only made it worse what am I paying for. Infuriating

  • faulkner84 Ghost (@faulkner84) reported

    @O2 It’s not the SIM card or the phone. I have friends on O2 experiencing the same thing and have even seen posts on TikTok about users experiencing problems with your data network

  • padrewill William Ingle-Gillis (@padrewill) reported

    @O2 - Do you do support by DM. Your support lines are closed, as is your online chat, and I've got a number port that I think hasn't completed.

  • LeakeKaren1 Karen Leake (@LeakeKaren1) reported

    @O2 Urgent. Please check you Google Play App My O2 Bill's and Payments And read the comments regarding the damage being done to yourself and Telefonica by the developer for the last listed update, preventing us from signing in and topping up plus other.
