These are the most recent phone user reviews posted by wildbill:
The ic402, ic502 and ic902 hybrid phones use CDMA for voice, iDEN for PTT. The problem is they only use 1900 CDMA band, where most CDMA phones have 850 and 1900. This causes them to loose voice coverage when 1900 is not available. I have been in rural areas on many road trips when my wife's Samsung M300 had 5 bars and my ic402 had NO SIGNAL.
