What Is The OneSimCard Universal International SIM Card?
It's your passport to low-cost prepaid cell phone service while traveling around the world. OneSimCard Universal global SIM card is a small electronic chip which when inserted into an unlocked GSM cell phone enables the phone with international mobile service.
The OneSimCard Universal SIM card is designed specifically for international travelers who:
Want inexpensive international cell phone service - Voice, Calls and Data around the world, including in the USA and Canada
Want to keep their domestic cell phone number while also having one European number (and an optional local or toll free Second Number) no matter which country they are in
Already have a unlocked GSM or 3G phone
Here's how it works: The OneSimCard Universal global SIM card comes pre-programmed with both a European and North American, Australia or UK number. In addition to the EU number, you will be offered a free optional 30 day US, Canada, Australia or UK number ( PEN - Personal Extra Numbers ) when you activate the SIM. You can keep your U.S., Canadian or other phone numbers by forwarding them to your PEN.
If you do not already own an unlocked GSM phone, you should consider purchasing an international cell phone bundle from OneSimCard.
