So yesterday I flew from Hong Kong to Ithaca, NY via the new Shekou Cruise Ship Terminal. There just as one walks in to the waiting room stood an international sim card vending machine. It holds phone sim cards for Thailand, Vietnam, Japan, Korea, Taiwan, Singapore, Malaysia, the United States and the Philippines. There are also internet sim cards for Europe, United Arab Emirates, India, Hong Kong, and Macau. So yes, this is a pretty reliable map of what are now know as “the one belt, one road countries”.
