O2

Hi, I currently have my double data volt benefit (40gb instead of 20gb) How much of that data do I have available when roaming in France?

Hi, I applied for an O2 sim. Moving over from EE. When signing up I was asked if I had a PAC code. I provided the code I had been given by EE. I have now received my O2 sim and have it in my phone. Do I need to do anything else regarding the PAC code...
