Ive not given tmobile a credit card or anything past my name and address. So my question is when my new iPad goes over the 200mb of data? Do they try to bill me? Or do they cut off my account? I'm just wondering if I need to monitor my data usage?
$1/kb, charged directly to your card.
Why would you not ask t-Mobile what they intend to do with your card before giving to them?
From what I gather, once your 200mb limit is reached you'll be prompted to purchase more data at that time for 1 day or 1 week. I'm sure it'll kick you to billing a that point. I think 1 day was $5 for 100mb or 200mb, not sure and 1 week was $10 for a Gig.
