A customer may get free phone credit when using i-wireless by registering for rewards using a Kroger Rewards Card, and then receiving the free phone credit by shopping in the store. A Tracfone customer may get free phone credit when using a promotional code when adding purchased airtime to the phone.
The phone credits offered by i-wireless are an option given as fuel reward points grow. For every 100 fuel reward points earned, a customer has the option to choose $1.00 off of future wireless service, as of 2015. Accumulation of fuel reward points begins within 24 hours of program registration. Points may be used every month to reduce the cost of service. They may also be saved, and accumulated, to be used to redeem a free month of service.
Promotional, or promo, codes are used as rewards of free phone credits to a person using Tracfone wireless service. Free airtime minutes are added to a phone when a customer enters a promo code during the process of adding purchased airtime on a Tracfone. The number of free minutes is determined by the exact code used. Free promo codes are offered to customers by text messages, emails and occasionally by postal mail.
