First, please ensure that you are not calling an international cell phone. Calls to international cell phones are charged at a higher rate than calls to land lines. Please review the product detail page for your card to view the cell phone rate.
If, however, you received fewer minutes than expected after using the card, please note that some cards have taxes or various fees. Taxes, unless otherwise stated, are deducted at the end of each call you make. Fees are deducted at various intervals, depending on the terms and conditions of the card. This can be the cause of a card providing fewer minutes that expected, because the number of minutes advertised on the website is based on the complete use of a card on one call. Please review the card information located on the product detail page. All fees, taxes, and rates are described in detail on those pages.
