Tata Teleservices is in final talks with Matrix Cellular, a international mobile roamins service provider. Talks with TTSL started when Matrix’s talks with Essar Group failed. According to a source, TTSL will take up 15 % stake in the JV and gradually raise it to 75%. Matrix is reportedly values at Rs.350 crore, but this valuation is likely to drop looking at the dip in sale of international travelling cards as the downturn called for lowered number of international travellers.
