Used 3G iPad, sim card in, how do I activate my 3G

[iPimpin]

I am having trouble activating 3G in my used (craigslist 32gig 3G) iPad with used Sim. How do I get AT&T to reset this so I can activate 3G service in my name?

can't you just get a fresh MicroSIM from AT&T?
shouldn't they be happy to provide you with a Sim if you subscribe to an iPad data plan?
