They are quite useful if you want the advantages of a digital phone, but regularly visit areas where analog is the only service available.

   dual-mode
   A mobile that can support two different technologies, such as analogue AMPS and digital IS-136 TDMA. Compare with dual-band. Three or more modes may become necessary as technologies such as cdma2000, UMTS TDD and FDD and TD-SCDMA proliferate alongside GSM, PDC, IS-136 TDMA and IS-95 CDMA. In addition, the need to support wireless LAN or Wi-Fi networks and Bluetooth will make portable devices even more complicated.
