    @O2 Also, why have I been told at more than 1 O2 store that poor signal is a known network issue, with no fix?

    @O2 @EnglandRugby Pay more attention to ur terrible phone coverage rather than worrying about the rugby match which you have no control over! Would be nice to get use of the service which your happy to take the money monthly for!

    @O2 But you’ve been out for a week? There’s. Big difference between fault free and a week of no signal

  • G4mvu Dave c (@G4mvu) reported

    @O2 The following site cell ID 1990790 LTE Band 20 is off air. The site has been going in and out of service since Friday 4th Feb. The 4G router attaches to the network obtains an IP address, then disconnects. Same with the mobile phone. Location M281yr. Shared Site Voda.

  • mark_g76 Mark Graham (@mark_g76) reported

    @O2 Thanks, but I can't get decent signal anywhere. It's either my phone or my aim card. It was never that bad with my old phone. Paid for this phone for a year and have had to spend most of the time having it tethered to my work phone!
