  • Page 4: General Introduction

    Cellular uses 800MHz and PCS uses 1.9GHz. The VX8350 support GPS Mode, we usually call it tri-band phone. Also, VX8350 works on Advanced Mobile Phone Service (S-GPS). We call it dual- mode phone. If one of the Cellular, PCS base stations is located nearby, Call fail rate of triple-mode phone is less than dual-mode phone or single-mode phone.
