the entry of viettel also saw further liberalization of the communication sector, where the government allowed private companies to lay their own optic fiber cables. the company had promised to connect several public institutions around the country with the optic fibre network and connect over 1500 villages to the telecommunication grid that were previously not served. the company also tried to partner with state-owned energy company tanzania electric supply company limited (tanesco) to use tanesco's power poles to serve as antennas, however due to high costs the plan was abandoned.
