With the addition of this Blackberry software, Vyke now offers its Mobile VoIP solution on the three most used mobile operating systems in the enterprise market namely Symbian, Windows Mobile and RIM. However, Vyke’s Blackberry solution is unique as it uses a variation of VoIP which enables users to make VoIP calls over the Vyke network at any time their phone has GSM coverage, not only when the phone is in range of Wi-Fi or 3G mobile data coverage.
