(Telecompaper) Tanzanian mobile operators are set to list on the Dar es Salaam Stock Exchange (DSE) in 2015 as part of regulatory requirements, Reuters reported. A law aims to allow Tanzanians to have meaningful shareholdings in the country's telecoms industry. Operators that could list on the bourse are likely to include Vodacom, Airtel, Tigo and Zantel. Mobile phone usage has shot through the roof in Tanzania in the past ten years, making the telecoms the fastest-growing economic sector there.
