    @RossUKRFC @O2 Been with @O2 20 years and no surprise box for me but signal lately has been horrific. Cornwall for a week could hardly get anything whilst friends we were with on Vodafone and EE were fine and festival the weekend couldn’t even send a text despite it saying I had 3 bars of 4G.

    @O2 I have no signal since 5.30pm last night, emergency calls only, nothing is stated on my 02 account as any issues in the area... Need phone for work... Awful service, out of contract, will move service provider!

    @O2 is o2 down in central London? Across Hackney, Islington and Kensington my signal keeps faltering between 5G/4G and data takes forever to load if it does at all?

  • zoespoor Zoe Spoor (@zoespoor) reported

    @O2 @KatyElphaba My signal is that bad that I can’t even open this! Takes ages then times out 😩 between o2 and @SkyUK I’m not getting a lot of work done!!

  • GambitJake JakeXGambit (@GambitJake) reported

    SO.... @O2 transfered my partners number over mine so I dont have a number for nearly a week. Consider the fact I have really serious health conditions o2 does not help at all to get my number back. I have no access to my health apps, my emails and banking. WTF?
