  • 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

  • mattlejog matthew (@mattlejog) reported

    Any idea about how to contact @O2 about an order. Not answering phone and tech problem when trying to contact from website!!

  • Graffi Martin McGrath (@Graffi) reported

    @O2 @e_emobile you guys are always banging on about you “great UK coverage” yet I go from Nottingham to London on the train and the coverage is terrible? I’d get a better reception trekking through the Amazon!! @UKgovcomms you keep telling us to use public transport?? Joke.

  • JSPrice_media John Saleh Price (@JSPrice_media) reported

    @O2 hi O2, I have an issue with calling on my phone. When I receive a call, or trying to call out, I can hear them but they can't hear me. Been like this for over a week and anywhere, i.e. not just my home. Anything I'm doing wrong? Settings are on for everything, 4G calling too.

  • DaveCoe1 David Coe (@DaveCoe1) reported

    @O2 Have an old hand-me-down Galaxy S7 that was originally a contract phone but is now using a payg sim card. Is there any way to prevent the message centre number reverting back to the contract number after I change it to the payg number?

  • SeanTwaddle2 Sean Twaddle (@SeanTwaddle2) reported

    @O2 I'm in France however my data roaming has stopped working , any help would be appreciated as I'm over here working

  • Jasonmgs Jason Rayner (@Jasonmgs) reported

    @O2 Hi need tech help. Can you help?

  • DaisythenGeorge Cheryl Flounders (@DaisythenGeorge) reported

    @O2 how do I speak to someone about changing my bill date. No where on the app/web allows it and your customer service number keeps saying “bye” and cutting the line!! 🤬

  • LeenaD74788779 Leena D (@LeenaD74788779) reported

    @O2 tried calling for the last three days! Nightmare. Keep getting cut off and your online help does not answer my questions. Been with you for years and now porting a 2ndnumber - need to know when this will happen and also how I get my 20% discount as I’ve text using temp no.

  • mattieallen289 Mattie Allen (@mattieallen289) reported

    I appreciate this is very *first world problems* but I ordered an Apple Watch with @O2 which was meant to be ready for pick up on the 10th and it's still not ready? It said "In Stock" when I ordered (on the 8th). Wouldn't have bought from them had I known I'd be waiting this long

  • aussierunning Andrew (@aussierunning) reported

    @virginmedia @O2 But if you’re an existing customer and don’t need a SIM, you’re forcing a new 18 month contract to upgrade. I’d pay £35 for the Hub4 and 1Gbps is available at the same price I pay today, but you won’t provide it unless I start a new contract… ‘computer says no’ - poor form.
