I will check this out, I would rather just get a prepaid sim and not have to worry about cancelling a plan. It's much simpler than worrying if they will charge my credit card again.
Thanks Tim
I believe that the prepaid sims Tim is talking about are for phones. I don't think there are any prepaid micro sims for iPads.
The other you have is to use you phone to tether your iPad to to gain web access if you phone will allow that.
AS far as cancelling the plan is concerned it takes about 30 seconds and you get an immediate acknowledgement.
