Radio ads are costly. There's no guarantee they will work (generate revenue for Go800), but they will reach a broad target audience.
GOIG's issue is that it doesn't have paying customers. Texters don't count for revenue generation purposes. If the end users/texters make demands on the businesses they patronize radio ads might work.
What markets will the radio ads be released into?
Billboard ads are much less costly by comparison and readers can visualize the text-to-connect message (text and graphics).
