AIM that is built in to the menu of a phone charges just like a text message - dont go crazy or your gonna end up making 1000's of .05 cent charges... doesnt sound like much it can add up to hundreds of dollars. AIM on t-zones is free to use if you pay the 4.99 a month for unlimited t-zones. And to the reply that asked about a contract - I would go with 600 for 39.99 with nts/wkds.. its too easy to use 300 mins with only weekends. Youll end up being smartaccess anyways so you will have a 150 dollar spending limit and then they cut your phone off until you pay.
