    @O2 I’ve no signal and the checker is no no issues in my area ?

  • pauldevenish Paul 🏳️‍🌈🇬🇧🇸🇪 (@pauldevenish) reported

    Hi @O2 I have received a scam call from an O2 registered number, saying they are from @currys - can I flag this up with you both, as they are using your network to piggyback off a company they don't work for.

  • ripinmypants Ryan Davies (@ripinmypants) reported

    @O2 your service especially 4G is so so poor travelling up and down the country a lot and I hardly ever have internet on my phone motorways usually .. time for a change any recommendations people ?

  • tedlewisdaly Tedlewisdaly (@tedlewisdaly) reported

    @O2 You've committed fraud on my account and have admitted to it several times yet you still have failed to call me. 7 weeks, 15 phone calls from us, messaged on Twitter and an official complaint submitted and nothing.#Ombudsman #ofcom

    @O2 Thanks; I just googled "is it normal to block popups" and as far as I can see it absolutely is, so maybe your website shouldn't be using them - particularly in a situation where a user is locked out of their account and has enough problems already.

    @O2 my signal was working one minute and then completely shut off. I’ve restarted my phone. Outage checker doesn’t say there are any issues?

  • wwfctom_ Tom🐺 (@wwfctom_) reported

    @O2 why do I never have any signal anywhere I go!!! Always have the no entry sign as signal

  • Chloe_Gibbs Chloe Gibbs (@Chloe_Gibbs) reported

    @O2 is there something wrong with your online chat service? Have tried about 10 times to use it at various times over the past day and every time it says all agents are busy.

  • EllanWicks Ellan Wicks (@EllanWicks) reported

    Hey @o2 as someone who has both their phone and home internet through you, can I please ask that for next years IOW festival you do something to pre-empt/manage the congestion? Every year everything is painfully slow for 4 days (in Southampton) and I can’t get any work done 😩

  • miles_fran Fran (@miles_fran) reported

    Been with @O2 for around 2-3 months. They have to be the worse network provider. Not even people In the shop can help and it’s impossible to find help or numbers online. Absolute joke
