  • AdamGrif1 Adam Griffiths (@AdamGrif1) reported from Penycae, Wales

    @wxmsmith @O2 Yeah. Was on Tesco mobile for years which uses O2’s network. Would constantly have 4G but it’d rarely work/load anything. Swapped to EE and no issues now 👍🏼

  • tonywhilding88 Tony Whilding (@tonywhilding88) reported from Wrexham, Wales

    @O2 not quite sure what I pay my contract towards, the service has been absolutely shocking for weeks now, 4G at times throughout the day is non existent and I know others have the same frustrations. Friends on other networks in the mean time have no issues.

  • harryt84 Harry (@harryt84) reported from Ruabon, Wales

    Hi @O2 how long should it take please to go live once my old network has turned off?

  • harryt84 Harry (@harryt84) reported from Ruabon, Wales

    @O2 Hi, yes I am, I've rebooted a few times. My old network turned off just before midday, but my O2 still isn't live yet.

  • meatloaf_efc DT (Meatloaf) (@meatloaf_efc) reported from Gobowen, England

    Hi @O2 can you please tell me why my signal keeps dropping out? Even when I'm standing still it will just drop even though phone says I have signal. Cheers 👍

  • sparklesnowdrop sparklesnowdrop (@sparklesnowdrop) reported from Wrexham, Wales

    @O2 a little concerning had text message to say problem with bill payment and to update details. My account is paid up to date #scam. Please be aware

  • harryt84 Harry (@harryt84) reported from Ruabon, Wales

    @O2 Morning team, I checked after and the girl from the shop who set it up, didn't put a sim in the phone! Don't know what kind if problems this will cause now, but out of WiFi I can't use it at all and obviously can't use sms or normal calling.

  • gibbsy55 David Gibbs (@gibbsy55) reported

    @O2 I ordered a new sim on the 26/8. Still not received.I called you Saturday and apparently you raised an incident-no response.I called yesterday to cancel-told I would get a call back same day-no response.Appears I can neither receive the sim or cancel it.What’s going on?

  • pawseygirl Louisa ⭐️⭐️💙💙🏆 (@pawseygirl) reported

    Remind me to never pre order an iPhone from @o2 again. The whole point of pre ordering is so you get it on the day it comes out, not a week later

  • Chefy_alicia Alicia Fenton (@Chefy_alicia) reported

    @O2 since yesterday afternoon my phone is not allowing me to make calls or send message or use date. The calls don't even ring. I haven't got a clue what's going on. Can someone help thanks

  • rhianna_joseph Rhianna Joseph #PrayForDemi ❤️ (@rhianna_joseph) reported

    @O2 my Mum is trying to an transfer of ownership and customer services said that they couldn’t help her because they are in South Africa and agent that she spoke to was really rude to her.

  • MCFC2012 MCFC Ant (@MCFC2012) reported

    Oh how I wished I stayed with @VodafoneUK never once had an issue with signal vaa dropping, @O2 are absolutely dreadful... 4 months of hell.

  • bellasguides Bellas Guides (@bellasguides) reported

    @O2 I'm having problems with cancelling an order. I've sent a DM but have now been promised that the order would be cancelled by 3 different O2 staff. Yet the order isn't cancelled!

  • samj326_sam Sam (@samj326_sam) reported

    @O2 your Western Favell store is poor! Completely incompetent staff who are rude and zero knowledge! A staff member tried telling me I was stupid for buying new apple watch ultra from Apple as O2 sold it for £549! I explained highly unlikely as it £849 everywhere else
