Very cheap apparently. I don't use it, but I see others using it.The main ndrawback is that they are noisy, like walkie talkies.
Depend on your needs and uses, but if you have many people with nextel to whom frecuently you call, it will be better and you can register their ID to call free between your monthly abono of Handy and off course as a currently celular phone, for instance I have and when I was in Mendoza I could talk with those whom are in Buenos Aires and on abroad too, if its country has Nextel.
