SIM solutions provider Bluefish has entered into an agreement with software service provider VIPMobile to jointly deliver Mobile WriteUp, a SIM-enabled application and platform to allow network operators to deliver a range of value-added services to subscribers.

Mobile WriteUP will allow GSM operators to take advantage of the growth in wireless messaging to deliver rich content to mobile customers using existing handsets, the companies said.

By way of a simple change of their SIM card, subscribers can create and access Mobile WriteUP sites, access rich content, directories and links, as well as buy or sell products and services.

The SIM-enabled application allows network operators to leverage their existing messaging technology to deliver unlimited and affordable content to their subscribers.

The Mobile WriteUp application functionality is delivered courtesy of the software residing on the SIM card. Bluefish said it has taken the standard SmartTrust WIB (Wireless Internet Browser) and extended its functionality with a series of plug-ins.

Field trials will commence in the first quarter of this year with carrier customers in Southeast Asia, said Wendy Pizarro, director of Marketing at VIPMobile.
