A SIM card allows you more options for international phone service.
BlackBerry phones are available through a variety of mobile phone carriers. These phones send and receive emails and cellular calls anywhere in the cell phone provider's network. Blackberry phones that are GSM-compatible can make calls anywhere in the world. To use your BlackBerry in Zambia you must prepare it for use on an international network.
Instructions
1. Contact your cell-phone service provider. Confirm that your BlackBerry comes with GSM or GPRS capability. As of August 2010, Rogers, AT&T, Cingular, and T-Mobile sold compatible BlackBerries.
2. Check your BlackBerry for a SIM card. If your phone comes with a SIM card, you will have access to international phone service even if your phone does not have GSM capability.
3. Consider your monthly cell phone budget. You can upgrade your phone plan to include coverage in Zambia, but some international cell phone plans require long-term commitments and cost significantly more than domestic phone plans. If you are traveling to Africa for a short time, consider a temporary SIM card from a third-party international carrier.
