"The year 2015 was extraordinary for Vivo because we consolidated the Company as a leader in the sector, from the combination with GVT; we advanced in the digital transformation with projects that generate efficiency and simplification of products, services and customer care; we built a unique culture and continue to believe in the country by maintaining investments over 8 billion reais focused on quality and expansion", says the Chief Executive Officer of Vivo, Amos Genish.
