    @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

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

    Still having signal issues with @O2 - over a week now! Spent half hour on Friday hanging out of a window making a call. Please can you update for LL572NQ - this is causing real issues working from home! You’ve admitted a mast issue, but when will it be resolved please?

    @O2 Just to add - I’ve also called your customer service number around 10 times. Each time I am told the new number will show in 24h. Nothing has changed in 3 weeks. I can send you screenshots of every call. I’m a new customer to 02 and the service has been absolutely abysmal.

  • ItzzJordan Jordan Kelly (@ItzzJordan) reported

    @O2 really can't wait to upgrade my phone worst network I've been on, ******* useless *****.

  • unicorn7132 Josie World (@unicorn7132) reported

    @O2 pressured into a 36mth contract, handset still being paid for but not fit for purpose (overheats, drops calls, straight to voicemail, Wi-Fi signal awful) Complained so many times but no reply! Bring on January 2022 as I will not be an O2 customer!!! Phones don’t last 3yrs

  • colls_5 Lee (@colls_5) reported

    @O2 We’ll I just phoned them and got told if it’s cracked it’s cracked. No it wasn’t. I spend a stupid amount of money on 3 contract phones with you and your trying to ****** me out of £92! Your customer service is a joke!

  • LukeBoulter5 Luke (@LukeBoulter5) reported

    @O2 is there any reason why whenever I go into my workplace signal no longer works. This worked perfectly fine until lunchtime Sunday and ever since I do not receive data or signal. As soon as I step foot out the building low signal is restored. This is Worcester High Street.

  • colls_5 Lee (@colls_5) reported

    @O2 really disgusted with the service from o2 recycle! I sent you a perfectly good phone which you had offered me £92 for. You then offered me £0 as it was still on find my friends, fixed that, then you offer £18 as you’ve seemingly cracked the screen! What’s next water damage?

  • d0ttyB Brittany 🏎⚽️ (@d0ttyB) reported

    @O2 no phone signal at all in South Wales SA14, a wasted trip to the shops as I couldn’t use Apple Pay! Properly embarrassing to walk out of the shops not being able to pay, and embarrassing that it’s 2021 and you’re still having signal outages 🥴

  • shadowstar240 Sarah Marie Jones (@shadowstar240) reported

    @O2 Are there issues in the SA15 area? I've had no signal at all (emergency calls only) for at least an hour and when I check the network status, it just says that there is a lot of traffic in the area. If that's the case, I'd expect at least some signal!

  • IzzyRothers99 Isabella (Izzy) Rothwell (@IzzyRothers99) reported from Meltham, England

    @O2 I currently have no signal in the HD9 area. Can you inform as to why this may be??

  • RyanAAllan Heather Chandler (@RyanAAllan) reported

    @O2 I cannot contact your customer service telephone number, and I cannot log in to my O2 account to use the live chat feature. I need to discuss why I can’t access my account, can you please help?
