    @tescomobile Turns out its your default DNS servers at fault, forced use of googles 8.8.8.8, once i did could get back online with no issues. Did a secondary test and rest back to default DNS and pack to pages not loading or timing out

  • wek04 Wendy Kimber 💙 (@wek04) reported

    @tescomobile having issue with connecting to Internet via my data, suddenly being asked for O2 password? Never happened before. And can't get onto chat either to try and resolve. Can send receive text/call. Any ideas?

  • X2Dean Dean (@X2Dean) reported

    @tescomobile found a mobile phone with one of your sims in. The phone is water damaged and will not light up screen so no way to see any emergency contact info.

  • dmh_872 Darren Hocking (@dmh_872) reported

    @tescomobile Yes... Surely as this is a rural area it shouldn't be that busy! Are you absolutely sure the network is not at fault?

  • ConnorMcUK1 Connor McNamara (@ConnorMcUK1) reported

    @tescomobile my signal has gone shite the past few days you all good? X

  • AmiBrundle Cosplays Empress (Ami) (@AmiBrundle) reported

    @tescomobile We were told that would be yesterday. But we have been told a lot. Like one person said you could change the delivery address and one couldn’t. One person told us to go talk to dpd. we’re told again to ring back this morning. And no told not till February. Great customer service.

  • DebbyJWatson Deborah Watson (@DebbyJWatson) reported

    @tescomobile …I am an existing customer please could you explain why there is a deal on line which offers 30GB for £11 (12mths) if you have a clubcard but your call centre state it is only available on 24month contract?
