SIM Cards

GSM cell phones, the norm through most of Europe, Africa, and Asia (Japan and South Korea are the exceptions) and now available for much of the USA, work almost anywhere. But boy, you can pay for it. If Maureen calls me to come up to floor 5 of Saks to check this new dress that looks good, the call goes via Australia even though I'm directly below her on floor 4. She pays to call my Australian number. I pay to have her call forwarded back to New York. No wonder phone companies make money.
