  • Stephen_Linton CupofStea 🏴󠁧󠁢󠁷󠁬󠁳󠁿 (@Stephen_Linton) reported from Bangor, Wales

    @O2 Thank you for the heads up, the postcode is actually a publicly accessible office where the signal drops out, so not a personal address.

  • madwelshgal 🏴󠁧󠁢󠁷󠁬󠁳󠁿 💜 Fi 💜 🏴󠁧󠁢󠁷󠁬󠁳󠁿 (@madwelshgal) reported from Bangor, Wales

    @O2 No signal whatsoever in LL572NQ- it’s not long been fixed after a mast problem which saw no signal for almost 2 months!Please don’t tell me there’s not an issue or to reboot my phone (done that). There IS an issue. Last time I reported it it took a month for U to acknowledge

  • kellykidd84 Kelly Kidd (@kellykidd84) reported

    @VodafoneUK are saying no issues with site even though zero signal. Interestingly @O2 also use the same mast & they have confirmed that the site is down and is being worked on. I'm told to "wait 24 hours" I mean come on! Time to look at another network! @O2 any good SIMO deals?

  • kevgraster Kevin Graham (@kevgraster) reported

    first time in 10 years, I’m ashamed to use @O2 ! I’ve always had an outstanding service, Now their service is unusable! I raised concerns about lack of data connection, they investigate and say resolved…still no data! But Ee with the same phone give 80 meg connection!

  • PaperGoat4656A 4656A (@PaperGoat4656A) reported

    @O2 I'm tryna get a replacement sim. Having no luck getting a response on My O2. Help me out please.

  • fellwalker10 All Over Europe (@fellwalker10) reported

    @O2 is the o2 priority scanning system working again yet in greggs? Apparently some issue with their in store till system and internet? Thanks

  • gazswain Gary Swain (@gazswain) reported

    @Thejourneyman01 It’s absolutely shite and @O2 will do nothing about it. It’s got to be the worst network out there. It’s not just the internet, calls constantly drop out.

  • Phillreynolds1 Phillip Reynolds (@Phillreynolds1) reported

    @O2 I have been into store to change my sim to an esim and got a message saying the sim swap request was successful. I now have no signal. I then followed the information given with the QR code to be scanned,says I need a text get a security text but I have no signal now. Help!

  • timmynorris90 Tim Norris (@timmynorris90) reported

    Imagine being with a phone network and when travelling around, and manage to actually call someone, all you speak about is how **** your signal is... But have to tell them over 20 different calls as always loose signal. @O2 Invest in your network!

  • DerrynMcMaster Derryn McMaster (@DerrynMcMaster) reported

    Hey @O2 - trying to get support, but my call quality is so awful I can’t call and every time I try the chat feature it just says you’re too busy to speak to me! Rubbish customer experience. Need to get you to enable WiFi calling on my account because you won’t fix the local mast!

  • drlajama89 Lor (@drlajama89) reported

    @O2 @EnglandRugby My signals a priority to me … my signal does not appear to be a priority to you.

  • Stuey3D Stuart Carr (@Stuey3D) reported

    @ispreview Christ I hope @o2 doesn’t switch of their 3G too quick as often it’s the only network that works as their 4G & 5G is often so congested it’s useless. Only thing that’s annoying is that @Apple removed the option to force the phone onto 3G with the 12 series and newer.
