Daily text and chat:
$1.00/day for subscription fee, then they offer unlimited nights and weekends. Days $0.10 a minute.  They also offer walkit talkie for a small charge and Wireless web for a small charge.
Pay as you go:
$.10 minute days, nights, weekends.  $.10 a minute mobile to mobile.  $1.00 per day Walkie Talkie service.  Wireless web $.35 a day.  Text messaging $.10 to send and receive.
They also offer many different phones depending upon your needs.
