| ANo.1 | It depends on operators and services. • PDC (Personal Digital Cellular) is a TDMA-based 2G technology and deployed only in Japan. • GSM is not deployed in Japan. • N900iG, M1000 (based on Motorola A1000), NM850iG (based on Nokia 6630), N600i and L600i are the only FOMA phones that supports GSM as well. Other FOMA phones are FOMA(W-CDMA) only. • Although SoftBank 3G is a W-CDMA service, almost all SoftBank 3G phones (except 802N, 703N and 905SH) are W-CDMA/GSM dual-mode for international roaming in GSM countries. • FOMA network and phones are based on an older version of W-CDMA technology (3GPP Release 99) while SoftBank 3G and foreign W-CDMA are based on the official version (3GPP Release 2000). They are not fully compatible. |
