How do you add airtime to a Net10 phone?

Net10 customers can add airtime to their phones by visiting Net10Wireless.com, clicking the Add Airtime header from the top of the screen and entering their 10-digit wireless numbers. Airtime cards are also available at select retailers for purchase.

Customers may add money online instantly from any card bearing the Visa, MasterCard, Discover or American Express logo and can enroll in Auto-Refill by saving their card numbers to ensure their lines stay active. Users can add airtime from cards purchased at retailers directly to Net10 phones by entering the airtime PIN located on the back of the prepaid wireless card or entering it manually online.
