  • jazeverettx Jaz 🦋🦋🦋🦋🦋 (@jazeverettx) reported

    @O2 hi I currently only have 1 bar of signal and my data is not working any idea how long till this will be fixed ?

  • CraigAlder Craig Alder (@CraigAlder) reported

    @O2 Yes it’s about the same issue. I’d just like to resolve the issue promptly, rather than it being left in a state of unknown, being passed between customer service teams.

  • markmccanney1 ScotsLawyer (@markmccanney1) reported

    @O2 @cmr824 Don’t do it is my advice. I upgraded over a week ago and the order remains “stuck”. Customer service is shocking. No one cares.

  • kennedy_lister Kennedy Rae (@kennedy_lister) reported

    @O2 Yes everywhere I go no dropping in and out of signal just dead? I’ve tried all the steps and still nothing
