    @NeilHarrison211 @madebygoogle @O2 Just sold my P6P last week! The pro sucks with that curved screen, battery, and fingerprint scanner. And what is up with the Internet quick setting? It's not so quick. Bring back wifi and lte toggle. Anyways, I took that cash and just ordered me an iPhone 13 Pro Max. Can't wait.

  • PaulFrase Paul 'no longer the Gigfather' Fraser (@PaulFrase) reported

    @O2 just redeemed the 3 month Disney+ freebie, I already had a 6 month one running on top of an annual subscription. I thought it would give me an additional 3 months but it's replaced my 6 month so I've in fact lost 2 months..... Can you help

  • NenosJa Nenos J (@NenosJa) reported

    Very poor service from @O2 again. Moving number from one O2 SIM to another. Was told it would take 24 hours or less. Lost my service on my old SIM after half a day but didn't get service on new SIM after 24 hours.
