Kristen if u have Verizon phone u can't use it in Nepal coz Verizon,sprint do not use sim cards and even there is no slot to use ur sim card on it they have something like TDMA,CDMA technology.But in Nepal they have GSM technology that requires sim cards that we use here in T-mobile,Cingular.Quad band phones might work like Motorola V6 but u have to unlock it first as others said.
