Concourse D has a Best Buy Express which may be your best bet on a Sim card. Wittman regional airport is near Oshkosh, otherwise you are looking at nearly 100 miles of ground transport at about 1.5 hours of travel time.
A couple of places in the airport. Depending on which airline you come in on. And a car rental. Highway 41 too Oshkosh.
Thanks for your answers. Mr. Huycke, unfortunately our company booked tickets to MKE, not Oshkosh, so we have to travel this time. We are traveling by Delta air lines.
