I would find something like this to be helpful. As a frequent traveler often you don’t have any sort of cell service when you land. Being able to quickly hop on WiFi is often a godsend for quick communication and navigation to final destinations in foreign countries.

As an example, in Copenhagen airport there is free WiFi but you have to go to wifi.cphairport.com to access it and if you don’t see one of the signs around the airport you won’t figure it out. Some handy guide that has URL, ID of the WiFi and password is super helpful in situations like this.
