    @EE currently having issues with an s21 ultra and galaxy watch 4 4g on @o2 (bear with me here) if I buy a galaxy watch 4 4g from EE with a data plan and get a mobile data plan for the s21 can they both use the same phone number? O2 can't seem to help me solve this issue.

  • ninsey_t janine (@ninsey_t) reported

    @O2 Why is my local area experiencing frequent 9hr long blackouts of no phone or 4g/WiFi signal? I'm paying for a service you aren't reliably delivering! Its incredibly inconvenient!

  • boulezian Mark Berry (@boulezian) reported

    Hi @O2. I have an urgent problem I need help with. I am out of the UK and have no Internet connectivity on my phone. I cannot find anyone to speak to by calling 202. Would you be able to help me, please?

  • HarryGarside Harry Garside (@HarryGarside) reported

    Any idea what’s going on @o2? Haven’t been able to use my data all day. Been in London and Kent so I don’t think it’s a local outage.

  • dave_fincham Dave Fincham Photography (@dave_fincham) reported

    @O2 Tried these over the course of weeks. I have direct call to your specialist team. I am paying £50 month with no service. I am tired , angry and anxious now. Promised call backs, nothing happens. @O2 @MarkEvansO2 #cancelmycontract #o2service

  • garethenglish86 Gareth English (@garethenglish86) reported

  • _Lizzie_03 𝕃𝕚𝕫𝕫𝕚𝕖 (@_Lizzie_03) reported

    @O2 Specific areas LU3 3HP is the worst It drops out from full signal to 1 bar and then E not even 3G! No doubt you’ll tell me you are doing maintenance works

  • SarahThirlaway Sparkly Sarah (@SarahThirlaway) reported

    @O2 can you please help I need to speak to someone on online chat but I can’t find it on your site anymore

  • quigdes Kevin Quigley (@quigdes) reported

    @philchamp_ @O2 @ThreeUK We were looking at all the options but the promised 20% discount tipped the balance back to O2. But like all these things it is a con. You have to "claim" the discount after you sign up. Well all I can say is O2 just lost me and the business as a customer. Truly fed up with this.
