So, you're saying that he gets 240 mins/month of voice plus 300 mb/month of data for 6 active months and doesn't have to pay a dime more as long as he stays within these limits? 300mb is a bit on the light side, but would suffice for email and basic web surfing (i.e. steer clear of video clips and downloading large attachments).
