How can you get free minutes on a prepaid cell phone?

To get free minutes for a prepaid cell phone from Tracfone, use a promotional code. Enter the specific code into the provided box during the process of adding purchased minutes. Free bonus minutes are added to the phone in additional to the purchased minutes.

Free minutes are also earned on iWireless prepaid phones by using a Kroger Card to set up a rewards account. As of 2015, Kroger's rewards account holders earn $1.00 of free cell phone service for every 100 rewards points earned by shopping at any Kroger's store. Reward points are also accumulated to equal a free month of cell phone service.
