Synway's SMG4004/SMG4008 series GSM/WCDMA/CDMA/UMTS/LTE VoIP Gateway is a multi-functional device that allows users to seamlessly move between mobile and VoIP networks. In comparison to the SMG2000/3000 series, the SMG4004/SMG4008 has more software functionality and a new hardware construction. Users can simply replace SIM cards without removing equipment thanks to a redesigned pop-up SIM card slot. It's also fully compatible with Synway's SIMCloud/SIMbank system.
