I am leaning towards getting a Verizon iPad over AT&T. I would be using the prepaid plan, but only occasionally, turning it on when I travel. Maybe some of you who already have Verizon on a no-commitment plan can help me out: (1) Is it easy to do this from the iPad, without having to deal with any customer service people? Assuming I use it at least every 5 months, which I've heard is necessary so that the SIM card doesn't get de-activated. (2) If the service hasn't been activated for a while, does the 30 day plan start from the time I turn it back on? I'm just worried that if the time period is fixed (it always goes from Mar. 17 - Apr. 16, for example), I wouldn't be stuck with a pro-rated plan depending on the day in which it's activated. (3) If I go over the data allotment, what happens? Can I just 'start' a new month right there? Is my credit card automatically charged or am I prompted to authorize the new charges? Thanks so much! My iPhone has always been on AT&T's post-paid plan, (and they have been super-easy to deal with through their web site and iPhone app), so this is new territory for me.
