What does the error message say? What does the control panel of the Jetpack say? Check the logs on the Jetpack by accessing its web admin page (Enter the IP address of the Jetpack into a web browser when your PC is WiFi connected to it).
Chances are that you either do not have global roaming enabled on your account, the Jetpack/SIM is not activated or there currently is no VZW service in your area. Need more info to confirm what is happening in your situation.
Emleach42, when traveling far from home having that coverage is imperative. We are here and happy to assist in getting you the service that you need. Prior to the trip, had you added international services?
