For instance, if you use a card with a 5-minute billing increment, a 1-minute call will be billed as 5 minutes, while a 6-minute call will be billed as 10 minutes. The price of the card will vary depending on the number of minutes and the desired calling destination.

Be cautious of additional charges like connection fees or maintenance fees that may apply when using a calling card. Some cards may deduct “maintenance fees” daily or weekly from your card’s balance. It’s advisable to carefully read the card’s terms and conditions before making a purchase.


Navigating area-specific numbers for efficient communication

When using a calling card, the backside of the card typically has a list of specific areas from which you can make calls. You should select the applicable area for you, dial 1, and then input the listed number. An automated voice will respond, and you should follow its instructions.

For instance, if you are using a calling card designated for use in New York, there will be distinctive numbers to call based on your specific location. If you happen to be in Manhattan, you will need to call a different number than if you were located in Hempstead.


PIN and remaining talk time

When using a calling card, you will find a unique PIN listed on it. Follow the automated voice prompt and dial this PIN when prompted. This automated voice may also inform you of the remaining number of minutes available on the card, providing an estimate of the duration of your upcoming conversation.


Dialing process

Here’s an easy guide to dialing the US from Mexico: Start by dialing the Mexican exit code (00), then the country code for the US (1), followed by the area code of the number you wish to call, and finally, the number itself.
