How the AT&T iPad 3G data plans will work

So the 3G iPad is set to launch this Friday at 5:00 PM, and AT&T has finally got on the ball and given full details on how their 3G data plan for the iPad will work. First order of business, you get two data plans that work in the US - the charges are automatically billed on a monthly basis, but you can start and stop that at any time right from the iPad 3G, and both options are contract-free:

• $14.99 per month for 250 MB
• $29.99 per month for unlimited data
• Unlimited access – no added cost – to AT&T’s 20,000+ Wi-Fi Hot Spots

That third one is a nice bonus. Basically, if you have an active iPad 3G subscription, then you get access to any AT&T Wi-Fi hotspot at no additional cost. The plans renew every 30 days, which starts on the date and time of the purchase, and charges appear like normal on your credit card bill. You can make changes to your plan at any time, which starts a new 30 day window. To manage all this, you go to the Cellular Data area under Settings on the iPad.

For those of you thinking about starting out with that $14.99 250MB plan, the iPad will actually alert you when you’ve got 20 percent of your data left, then again at 10, and finally once more at zero. As each alert pops up, you have the option to add more data, if you so choose.
