It does not cost money to roam in most places when you have metro. In the Metro Extended Home areas it roams on Sprint with free unlimited talk text and unlimited data, most times you can get data, now you can also get 3G. If you roam in a market that has metro coverage or if you roam where Sprint has no coverage you roam on TravelTalk where its free unlimited texting then 19c. a min. They take money from your MetroConnect account so if you haven't added money to your MetroConnect account you cant initiate calls on TravelTalk.
