How to Get a Free Chirp on a Boost Mobile

1. Subscribe to Boost's monthly unlimited plan. This gets you unlimited chirps, talk minutes, texts, web access, 411, instant messages and email. Pay an additional $5 per month for unlimited international plans.
2. Live, work or vacation in Baja California, Canada, Chile or the United States. Boost Mobile's walkie-talkie feature supports only these territories, as of November 2010.
3. Give your 'Boost Walkie-Talkie Number' to your family and friends who have cell phones enabled with the walkie-talkie feature through Boost or Nextel.
4. Listen for the chirp sound on your phone. When you receive a chirp, your phone's screen will say, 'Private in Use.' The chirp sender's 'Boost Walkie-Talkie Number' will also display.
5. Answer the chirp by pressing the 'Boost Walkie-Talkie Button' on the side of your phone. Keep pressing this button as long as you are talking. Release the button to hear the other person talk.
