Very low-cost VoIP-based mobile phone calls using standard mobile phones are promised under a new service called FlashTXT launched by Talecom, previously known better as the developer of the Wireless Delivered field service applications platform (which continues to flourish).

FlashTXT users install a simple, free Java application on their existing handset (platforms such as Symbian and Windows Mobile are supported), and calls and messages can then be handled via a transparent link to a VoIP channel. Texts between existing FlashTXT network users are free, and voice calls can be very cheap.

The launch marks a change of gear for Talecom, which has been building up its resources by recruiting some heavyweight executives from the telecoms sector to drive new initiatives.

From a corporate point of view, to begin with the company is mainly targeting major wholesale customers such as broadcasters and football clubs, through which it will offer potentially profitable value-added services such as premium calls (ideal in “voting” scenarios, on which revenue share arrangements will be offered).

However, typical business users could also benefit from the low call rates and cheap or free GPRS-based texting.
