We’ve all been there: You disembark the plane, make your way through passport control, collect your luggage and, before you carry on your merry way, you make a pit stop at the airport to purchase an overpriced local SIM and text everyone back home to alert them of your new number. You know that, if you don’t get the SIM, your phone either won’t serve you any good, or you’ll return home to hundreds of dollars in bills. So you pick your poison. But you neither have to change your SIM (and, effectively, your life line) nor rely on exorbitant international plans. Travel the world with unlimited data devoid of inconvenient SIMs and costly roaming fees with these portable Mi-Fi devices.
