  • Atanvarne ㄥ乇乂丨乇 (@Atanvarne) reported from Broxbourne District, England

    @O2 That’s it. They thought that 7am was a decent time to call a customer, even without knowing that I work shifts and was working late last night. 9am I’d have considered acceptable. I wouldn’t have liked it but 9am is REASONABLE. 7am is absolutely NOT.

  • GpopIrl Gene O'D (@GpopIrl) reported

    @O2 is this a legitimate number to be called from saying its your customer service? 02922770457

  • MarkKeenan5 Golfy Mc Golf Feet (@MarkKeenan5) reported

    @O2 how come I can get 5g in calador Mallorca but can barely get a bloody signal in SN25 Swindon?

  • gucciarllo Gucciarllo (@gucciarllo) reported

    Opened a new @O2 phone contracted and selected to collect today in store, but after paid the upfront they ate my collected date for the 19th, I got so annoyed and decided to cancel the plan, now I have to wait how many hours for my refund from the upfront ? So I can go to EE

  • Seanson78 Sean Robertson (@Seanson78) reported

    @O2 Hi Guy, landed in Italy this morning and roaming data not working. Seems like I might need to request to have the roaming bar removed? Please can someone assist?

  • nightanddaygr nightanddaygr (@nightanddaygr) reported

    @O2 I have been having awful 4g &5g speeds in central Bristol. BS1 postcode, in some cases the network is barely useable.

  • aristaebrahim2 Arista (@aristaebrahim2) reported

    @O2 QR code not working really embarrassing

  • mjb8028 Mark Bush (@mjb8028) reported

    Stupid question maybe, but with a sim only contract on @O2 if my phone was to die can I just get a phone from anywhere and put my current SIM card in it (as long as it’s the same sized sim) doesn’t matter if it’s apple or Samsung or anything like as long as that phone is unlocked

  • IngridLaycock Ingrid Laycock (@IngridLaycock) reported

    @o2 why are you kicking your customers off the helpline when you tell them to phone you for help? #notverycustomerfriendly

  • eastendjack13 john jackson (@eastendjack13) reported
