If you happen to pick holiday destinations on the pages of National Geographic, you better make sure you´ve got a cell phone that will serve you well. The Duet D888, introduced by Cellular Abroad and National Geographic looks up to the task indeed. The device utilizes two SIM cards simultaneously, but is, unfortunately, a tri-band GSM (900 / 1800/ 1900 MHz) only, meaning it´s not entirely usable in America.
Cellular Abroad offers the Duet D888 for $199 along with a prepaid National Geographic Travel SIM that provides low rates with 185 countries, free incoming calls in more than 90 and 30 free outgoing minutes in most of them. The SIM card itself is assigned a British number and costs $79 if ordered separately (and not along with the handset). The other slot can be used to plug in a local SIM from the country you are in, so as to get even more cheap minutes.
Well, where are you next leaving for?
