Vyke Communications (Vyke A/S) is a Voice over IP telephony company with a focus on Mobile VoIP and IP SMS using S60 supported mobile phones without the need for additional hardware. Vyke allows users to make telephone calls and send SMS over the Internet via their mobile-handset, computer or a normal fixed or landline.
Vyke offers free calls and SMS between connected users by utilizing existing Wi-Fi and wireless zones, existing mobile phone provider Internet networks and proprietary software. Additional services available to Vyke subscribers and customers include more traditional VoIP technology such as computer–to-phone calling, callback (where two nominated numbers are connected by Vyke via SMS, computer-initiated or callback number request), computer-based SMS and several other initiatives in development but available for Beta-testing through Vyke Labs. Apple Mac computers and platforms are also able to use a specialized dialer for Mac-to-phone calling.
Vyke offers free calls with only a one time connection charge to countries such as the United States, Canada and most countries in Western Europe. Hence it falls under the free or almost free VoIP providers. Vyke for mobile sends text messages over the mobile operator's data channel.
