Yeastar UMTS Module (1 UMTS Port) (1 SIM Port)
UMTS is based on the WCDMA technology. So WCDMA (Wideband CDMA) and UMTS (Universal Mobile Telecommunications System) are used interchangeably these days. They are third generation wireless network technology which allows speeds of up to 2Mbps. Both these technologies are essentially 3G technologies, providing voice and data services at a higher data rate than the traditional 2G. UMTS voice call is also available when you install UMTS module in the Yeastar S-Series VoIP PBX.
