    Quite shoddy of @O2 to refuse me a contract as a new resident of Northern Ireland when my driving licence is in the Republic of Ireland and not offer an alternative verification or reply to my email of complaint from 6 days ago.

    @O2 please fix your data!!! Paying for something that doesn’t even work!!! Signal is shocking no matter where you are. Absolutely nothing loads or refreshes. Fix it !!!

  • statsdavew Dave Woods (@statsdavew) reported

    @O2 Just data. Tried manual network selection - no difference. But came back this morning (and with great 5G speeds from @COSMOTE). Fingers crossed it was a temporary network glitch!

  • iainkernaghan Iain (@iainkernaghan) reported from Redhill, England

    Well @O2 i nearly upgraded my phone. Shame you misled me on your black friday airtime discount, wiped the basket and now just give me "400 bad request" pages. "Help" is useless, just loops of questions...

  • XxX_EMMA_XxX Emma (@XxX_EMMA_XxX) reported

    @O2 I have the Travel inclusive add on as part of my contract. Never had an issue before, but landed in USA yesterday and it’s telling me if I want data I have to pay £6 per day. My app says my add on is active. Is the text a mistake?

    @O2 I have upgraded two phone accounts with you, not sure what the issue is, but you cut my service because you sent a new sim out for the other phone, thought I got that corrected. You agreed to send another sim and not to activate it, I'll do it when it arrives. Now you have

  • babywearingmam wiggle your ankles! (@babywearingmam) reported

    @O2 Useless, saying you’re aware of the issue doesn’t solve the problem that’s been ongoing for months. My husband has no issues using his phone here because he’s not on o2!

  • babywearingmam wiggle your ankles! (@babywearingmam) reported

    @O2 why can I never get signal in my town? It’s ridiculous that I can’t use my phone when I’m shopping. It’s 2022! I’ve had this problem for months now, I don’t understand why this is so unreliable?

  • KaneNay2504 Kane (@KaneNay2504) reported

    @O2 absolute joke been a week since I’ve ordered and still not got the phone, DHL are a shambles and o2 not doing anything to help or progress!!
