You have different options for adding credit to your National Geographic Global SIM Card including online and directly through your handset.
Re-charge credits for the Talk Abroad™ SIM Card typically add 42 minutes worth outgoing talk time to your SIM card.
Per minute rates are determined by location and are billed against your recharge credit. Please see our rate calculator.
Online Top-Up Service
Add call credit in US$29 increments or chose Auto-Credit in the shopping cart and your SIM card will automatically add $29 of credit any time it falls below US$10. The Auto-Credit add-on is the best way to ensure that you will not run out of call credit while still being in control of your costs.
Manual Top-Up Service
You can manually add credit to your account whenever you need to by dialing *161# followed by the call button. Your new balance will be displayed on the screen of your handset. You must register your SIM card online and enter your credit card details in order to use this service.
