  • JadeWheatley_ Jade Wheatley (@JadeWheatley_) reported from Paddington, England

    Had a ridiculous amount of issues with @O2 of late, and despite numerous calls and messages, there’s no resolution. I wish this had happened before I upgraded and then I’d just leave! We’re now another day of no service because of SIM card issues with no help! 🤬

  • jameskibwe James Miller (@jameskibwe) reported from Stratford, England

    @O2 Two weeks at least. Slow speed, but worse, the connection dropped today too, even though I was still on the O2 network, but service stopped momentarily anyway and this threw a spanned into the works at a delicate moment online.

  • Blurred_Lynes Rhian (@Blurred_Lynes) reported

    @O2 I submitted a complaint on the 24th March and reicevr and mail saying I'd get a response in 7 days. It's now been a full month and I haven't heard anything. Appreciate sometimes it is busy, but what is your current response time?

  • tacjets Aaron (@tacjets) reported

    @O2 Seen other tweets on your feed this morning. Suddenly last 2hrs Roaming in France has stopped working - no service for either my or partners 02 phones. Been fine roaming with 4G signal last 3 days just last 2 hrs stopped working. We have restarted phones multiple times....

  • tacjets Aaron (@tacjets) reported

    @modernbeauty_ @O2 @modernbeauty_ my roaming in France not working either along with my parnters too. And someone else tweeted their roaming not working in Ireland. Definitely something wrong with 02

  • btstob 𝚊𝚖𝚢⁷ ♡ (@btstob) reported

    @O2 hi, my roaming isn’t working in greece and i have no signal. sent you a dm, can you help?

  • MumblerJamie James H (@MumblerJamie) reported

    @O2 I got through shortly after the tweet, but I also need to cancel the current contract so the new one can start. However, the guy I spoke said the old number I was trying to transfer over and replace the temporary one with was already connected to my account.

  • 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.

  • viranrpatel Viran Patel (@viranrpatel) reported

    @O2 my Esim has no service and your online customer services have no agents available. How am I supposed to resolve the issue? I have a French mobile number you can contact me on as i am abroad on holiday

  • tacjets Aaron (@tacjets) reported

    @RichMoors @O2 @richmoors even though 02 are saying nothing is wrong with their service. Last 2 hrs for me and my partner phones Roaming is not working in France, been fine last 3 days
