I got a US roaming add on before I got on my flight to the US, 3ALL. I had to talk to a rep to get it added since I had issues activating it through text. How long does it take before it shows up on my self serve and usage dashboard? I already got the confirmation in my email and activation of the add on by text. I started roaming already but it does not show my updated usage. Also, all activations and expirations on Mountain Time?
