This is my newest toy for travel data access while in the U.S. Karma provides a nice simple package. Clean and straight forward. The first paper is about blah blah blah regulatory information and a general disclaimer about wireless not being 100% guaranteed in all places at all times. Just legalese.
Then there’s a simple page that details how to use a power button in the one side and the url to use to get your account hooked up on the Karma end of things.
After this avalanche of paper, just a device and a USB charging cable. No wall adaptor, but I think it’s a fair assumption that anyone needing this device has a computer or an adaptor that speaks USB and A.C.
