you go to men u and then walkie talkie and check off up to 20 people ... then hit the PTT button ... viola
you can also go into your contacts and make a group (second option on the top ie: new contact; new group) .... once you open up that menu you can either add people off your contacts list or imput the DC number manually ... this only works for nextel i870 as far as i know ... i have been told Boost does not have SDGC ... sorry
