Are you tired of paying enormous bills for international roaming service from your mobile phone provider? Then consider purchasing a National Geographic Duet Travel Phone or Travel SIM card.
The Duet includes National Geographic’s pay-as-you-go National Geographic Travel SIM card, allowing affordable calling in 185 countries, free incoming calls in more than 80 countries and 30 minutes of outgoing call credit for most countries. Users have the option of inserting another SIM card in the phone and having a secondary number and service.
The National Geographic Travel SIM card can be purchased separately from the Duet phone for those travelers who already own a cell phone that is compatible for international use.
