  • cornelius_mark Mark Cornelius (@cornelius_mark) reported

    @O2 Got to say your 4g is getting worse and worse especially I'm last few months. Unable to connect more often than not, Plymouth, Devon, Cornwall, Wales and Greater Manchester. Adding virgin mobile customers to an already over subscribed/ congested network not a great idea!

  • dapsy7 claire audley (@dapsy7) reported

    @O2 is it possible to order a replacement sim, having issues getting any more than 3g and just realised i use old sim each time i upgrade :/

  • RutterLindsay Lindsay Rutter (@RutterLindsay) reported

    @O2 We live at PR6 9ES and have up to date mobile phones using o2 sims. Recently our voice/text/data signals are very weak/intermittent; at times no coverage. No fault or outage shown on your website. Why have we such poor service?

  • minshyjay JackieEm (@minshyjay) reported

    Hi @O2 I’ve had no mobile signal at all for the past 2 days but nothing noted in your network issues for this area. Phone all updated and checked as per your online advice, rebooted etc. Can you advise? Postcode PR6

    @O2 When are you going to reply to my mother in law’s complaint about her mid sold contract?

  • ludast22 Luka (@ludast22) reported

    @O2 1/3 I cannot believe how unbelievably unhelpful, passive and outright lazy your company has been. After being charged over £200 excess in unlawful billing, which I still haven't been refunded for after over two weeks, I've also been without phone service which has made me

  • Jimbobthon James Richards (@Jimbobthon) reported

    @jammergilmore @O2 Also, because o2 and Virgin merged. O2 are moving Virgin customers over from Vodafone (who they shared with) to O2. So, expect the network to be throttled everywhere. Really should have increased capacity first.

  • ludast22 Luka (@ludast22) reported

    @O2 2/3 miss doctor's appointments, work calls etc. I've called customer service countless times, with no outcome, often having the line go dead after waiting 20 minutes. I've gone to 02 stores which haven't offered any support either. I've emailed complaints team which haven't

    @O2 I got a new phone yesterday and opted to keep my old number. I was given a new sim but it’s set up for a different number! Can someone help?
