Keith,
I am thinking of getting a US based carrier sim card when in the US as my Roger$ contract is near completion, and for only $40 I can have My iPhone unlocked from the Roger$ network.
I may try this fall when we venture to Oregon for the rally. My iPad is theoretically unlocked as I bought through the apple store, so I should be able to put a sim card from any carrier into it. I don't want to have to pay for the months when I am not in the US, so a monthly plan or a fixed data amount plan.
Bob,
Also looked at mifi plans, which would also work. Do you have a mifi unit (multiple devices can use it) or a card that is dedicated to one device? Supposedly the wifi rqnger is designed to let me plug a card/stick into it and then it is a router using the card's data.
