Our beemo driver has asked me to bring over a mobile phone for him as his one is on its last legs.Someone has given me a secondhand one, i'ts a Samsung modelSGH-x460 and it may need unlocking to use in Bali. My driver has asked if the phone is CDMA/?. I'm really out of my depth on the technical and wondered how to get around giving him a phone that will work with a Bali sim card(at least I know what a sim card is)Gratefull for any help. CHEERS.
