Here is a question I saw someone ask on another forum. No one had yet given an answer but I thought it was an interesting question so I will pose it here. If you travel to, let's say the US, would it be possible to purchase a micro sim card for a carrier there and use it in the iPad so as not to incur roaming charges for your service in Canada or visa versa ? Will it depend on the type of service the US has since in Canada the iPad data plan is monthly, no contract. .
