    @O2 - no service for last couple of hours - any ideas why? The old turn on and off trick isn’t working. Is there an outage?

  • tamlahill1628 Andy Bhoy (@tamlahill1628) reported

    @O2 Emailed o2 sad 😢 Hi. I ported my number from 3 to o2. The transfer happened yesday & since then I have had no signal/connection to network. It’s been over 24hrs. I can’t call o2 as I have no service. Any ideas ? I have switched off/on phone several times with no success.

  • ThisIsJamesM James M. (@ThisIsJamesM) reported

    @O2 Yes, tried a few things, including turning off ‘Dial Assist’. I could phone people on Tuesday, I couldn’t on Wednesday. If I dial the number manually, it works, including as a full international number. Inbound calls are fine and the contact lookups work without issue still.

  • dease21 Dease (@dease21) reported

    @O2 Still no help here, spoken to 5 people in an hour and still no help! Honestly the customer service is just a joke and they all say “I will transfer you to the correct department and also tell them your problem!” AVOID O2 at all costs

  • argen Bruno Belcastro Pinto (@argen) reported

    @O2 hi, I’ve taken a SIM only contract but cancelled during my 14 day cool off period but still received an invoice via email. Can you please advise why? I was told to cancel the direct debit and that there were no charges.

  • 3enLiam 👊🏻🔰 (@3enLiam) reported

    @aimeeevans96 @O2 I'm having the same issue I've taken the sim out etc. But haven't had signal since Tuesday? Can't receive a call or won't go to voicemail...
