    @O2 I’m having issues with my data roaming - it’s not working at all on either of my numbers. Never had an issue before. Can you please help?

  • THEWHITLAM THEWHITLAM (@THEWHITLAM) reported

    @O2 over the past 5 years the 02 data signal in Scarborough has got worse. Apparently they’re working on it … do any other carriers offer an excellent data signal in Scarborough ?

  • 1555Kirsty j.kirsty.j (@1555Kirsty) reported

    @O2 Well that's kinda stupid so I've lost out totally cos I can't get anything now if the voucher isn't used then it should be available to use another one cos it hasn't been used

  • hihiimaminorr im not not a minor (@hihiimaminorr) reported

    @O2 your customer service is absolutely useless, i was told to wait 24 hours for my sim to activate. then i was told that i would have to go into store to activate however i can’t do that as the contract is under my dads name. i can’t change the details so they are in my name

  • katyguest36912 Katy Guest (@katyguest36912) reported

    @O2 @O2 please will you let me know how to contact someone about this? I'm appreciative of your colleagues' help in DMs but I can't wait 12 hours between replies or I won't get this resolved for days. Please can I call a help centre or something?

    @O2 any eta on when the mast will be fixed covering CB25 area? Can't use 2fa to access online accounts! It's not the first time recently it has gone down.

  • SoNowUknow2 James (@SoNowUknow2) reported

    @O2 I have an iphone that I have had for years and I now find it is locked to O2. I was using a giffgaff sim so no problem until now. I want to unlock the iphone to any network as a backup. I do not have an O2 account. Can you help me unlock my iphone?

  • EdFurnell Ed Furnell (@EdFurnell) reported

    Hey @O2 quick question. Why is it sometimes easier if I switch down to 3G for my internet to work when travelling on a train. Often my phone says it has signal and 4G… but actually there is no internet connection. It’s 2022. Is it too much to ask for signal everywhere?

  • SmallCharityFR Fiza #BehindYouSkipper (@SmallCharityFR) reported

    @O2 hi, I just tried using a priority code for Odeon and it’s not working

  • CMorgan1993 Craig Morgan (@CMorgan1993) reported

    @o2 I cannot believe the shocking customer service I have received from@this company, I’ve had an issue since April and was told to get a sim replacement…the person didn’t even look at the area and there’s a mast down which wouldn’t work with a new sim anyway
