    @O2 are gonna have to either offer me an amazing deal or sort out this horrendous signal issue. How can I not load a twitter video when I have a full 4 bars of 4G signal

  • CraigFamilyBlog Hayley & Gavin (@CraigFamilyBlog) reported from St Albans, England

    Gav and I have had no mobile phone service for 3 days, but I have no service to call @virginmedia to let them know! It happens far too regularly. Just spent the morning searching for a new deal. @O2 looks like the best so far!

  • AddictiveColors Addictive Colors (@AddictiveColors) reported from London Colney, England

    @O2 I understand that carriages speed and materials do not help, but repeaters in tunnels sure would to avoid disruptions especially as they can particularly nasty to a laptop when the phone or the train is the hotspot as that side of the connection never goes down just the gateway’s

    @O2 Hi, it’s been 2 weeks since i started receiving non stop calls from your call centres to get me get a plan with you, the caller said that i entered some kind of contest or signed up for this but i never did since i am happy with my current provider. This is very inconvenient

  • SinaedDavis Siiinaed (@SinaedDavis) reported

    @O2 any idea when your service will be restored in the TD14 area? Been awful for nearly 2 weeks now. Can't even make calls or send texts. Website originally said today for it being fixed but now just says it's been worked on.

  • OliverBanks Oliver Banks 🇺🇦 (@OliverBanks) reported

    @O2 Made a complaint a few weeks ago which I was told was resolved. Been sent an incorrect bill as it hasn't been resolved. Emailed the direct email of the person who dealt with the complaint - no response. Now receiving termination emails, have no data on my device?

  • TwSport0 TwSport (@TwSport0) reported

    @Clf88 @O2 Oh ahh Yh that’s annoying, I’ve had issues for months and numerous complaints and they don’t do **** Yh I’m thinking EE or voda but depends on price

  • MRrokirokosz rokirokosz xĐ (@MRrokirokosz) reported

    @O2 You are offering 10gb of internet at an expensive price which is ridiculous Plus this internet doesn't work in 50% of places in London. Unfortunately I have internet with you because I was tempted by the mix with virgin broadband. I can't wait to leave you when my contract ends

  • abivedder Abi (@abivedder) reported

    Argh, my phone @O2 and my internet (THREE 5G broadband) @ThreeUK5G are both down 😤😫 it been like this for 2 days. Learnt all about jitter & latency. @ThreeUK your jitter is baaaaaad. It needs to be easier to get out of contracts when they are not providing what you pay for 😤
