    @BradyHaran @O2 One time I disabled Airplane mode while flying over Canada, I somehow managed to get some cell service and realized that when I received a text message saying my bill was reaching 80€

    @O2 @pchavda Having to reply from a colleagues phone. Reported this morning at 9 o clock. Still service-less. Bet you’re still charging full rental though.

  • sarahbennetto Sarah Bennetto: a comedian of sorts. (@sarahbennetto) reported from Fingal County, Leinster

    @O2 hi guys. My phone stopped working in Europe (since I added an Aussie E-sim). No one in your O2 UK shops can help. I even deleted the E-sim. But still: no roaming. O2 said I should wait until I’m in Europe for work again and call you (I can’t; that’s the point!). Help me, pls?

  • DevaConUK DevaCon (@DevaConUK) reported

    @O2 I'm trying to contact Collections but all calls don't get through. I am receiving no texts from anywhere including govt sources and security checks. What is your customer service number? I'm in Chester where you have little signal.

  • DomMog86 T (@DomMog86) reported

    @O2 Hi, my nearly 6 month old S22 keeps dropping signal during calls resulting in robotic voice, stuttering, long silent periods during a call. This has been happening for a while. Any suggestions on how to fix this? Thanks.

  • rita_swig Dee E Smith (@rita_swig) reported

    @O2 I have now been disconnected by your operatives 3 times whilst trying to reinstate my account. I won’t bother if this is how customer service is.

  • Pauljon58861534 Paul jones (@Pauljon58861534) reported

    @O2 Don't buy from 02 they sell shoddy goods and will take no responsibility and they leave the customer holding the bag!

  • malt_11 ashley (@malt_11) reported

    @o2 trying to talk to customer service, chat is unavailable as is via my app, getting frustrating trying to talk to someone re upgrade 😳😳😳😳😭

  • SissyTeee Sarah Taylor (@SissyTeee) reported

    @O2 the mast in HD9 4AP is not working again. This is the 3rd time in January! This is an ongoing problem and you can continue to ignore it (and me) but I will not be renewing when my contract comes up and nor will many others. Your network is just too unreliable.

  • LyannaReed Lyanna Reed (@LyannaReed) reported

    @O2 No network coverage again today.. this happens every other day these days with no message to inform of issues. Never any apology/discount and you expect us to pay our bill every month. Had enough!

  • AnnaAverkiou Anna Averkiou Media (@AnnaAverkiou) reported

    @O2 I've tried all that. Spoken to CustServ who can't help: it's just due to lots of people using it and it's being worked on! WHAT is being worked on? How long? Will I get a refund on my subscription? :-(

  • Serena_90 Serena Taylor 🏴󠁧󠁢󠁷󠁬󠁳󠁿 (@Serena_90) reported

    @O2 sort our signal out!! Paying for eff all at the moment, can't even make calls 🤬

  • twitpete Peter McIntosh (@twitpete) reported

    @O2 my new O2 SIM is not working after my number was ported. I've tried restarting mobile many times. Sim 1 not provisioned is the message. No calls/txt/data for last 8 hours. Please can you help? Thanks
