CDMA

CDMA stands for Code Division Multiple Access. This is a digital phone technology allowing many users to use a network at the same time. CDMA is fundamentally different to GSM in the way it handles radio signals. Because of this, CDMA phones cannot access the GSM network and vice versa. Since amichi is part of Australia's GSM network, a CDMA handset cannot be used to access amichi services.
