    @O2 hi guys. My phone stopped working in Europe (since I added an Aussie E-sim). No one in your O2 UK shops can help. I even deleted the E-sim. But still: no roaming. O2 said I should wait until I’m in Europe for work again and call you (I can’t; that’s the point!). Help me, pls?

    @O2 @pchavda Having to reply from a colleagues phone. Reported this morning at 9 o clock. Still service-less. Bet you’re still charging full rental though.

    @BradyHaran @O2 One time I disabled Airplane mode while flying over Canada, I somehow managed to get some cell service and realized that when I received a text message saying my bill was reaching 80€

    So once again in overseas in Spain and I can’t get any internet access other than free Wi-Fi. @O2 Should be so much hassle to get same service in Europe. #roaringfail again

  • GazWeetman Gaz Weetman (@GazWeetman) reported

    @O2 Thanks for the swift reply. I tried to turn off “automatic network selection” and it just did the ‘buffering’ sign for minutes without producing any other options?

  • HezBarr Heather Driver (@HezBarr) reported

    @O2 currently in London with a 5g capable sim and phone yet only getting 4g! My hubby with same phone can get 5g. Don't know what's happened to my phone help!

  • BrianCo48405777 Brian Cope (@BrianCo48405777) reported

    @O2 Perhaps you'd give me the courtesy of a reply to my reply. As things stand O2 have locked up £25 in a sim. Please advise how this problem can be resolved.

  • PunitGoyal1 Punit Goyal (@PunitGoyal1) reported

    @virginmedia Part4: same team also advised me to get a O2 sim, saying that if I add that sim to my existing package, I will get 4£ per month discount. Which I didn’t get. Upon talking to O2 customer care, they said loyalty discount is for older customers. @O2 @TheO2

  • crels Crels F (@crels) reported

    @O2 what is the process for porting my number onto your network. Keep getting cut off from your telephone customer services. I have the EE PAC code. Thanks.

  • jjacqqui Jacqui (@jjacqqui) reported

    @O2 can you tell me if, when I reach my data cap of £51 for using data outside Europe zone/uk, my phone will cut off? I can’t find answers to this anywhere. I need to add more data from Morocco but don’t know how. Stuck in crazy driving situation + no Google maps! Help!

  • Richie0079 Richie (@Richie0079) reported

    @O2 Hi guys, I've dropped you a DM with regards a PAC code not working. Thanks.
