said by meister_sd:funny how they can authenticate a simcard/home location register in real time, but it takes 'longer' to count the usage. said by cahiatt:
I would expect a check every day or two on the online account would have revealed an issue to the account owner before it got out of hand.
Most roaming done outside the network won't show on your bill until the roaming partner submits the bill, which can take a month or two. That's why when you login to your ATT account to check your data usage, they usually say something like "it can take up to 24 hours for data usage to be viewed".. Something like that.
