Narcizo has left the role to “seek new opportunities outside of Nokia”, and Diliani will take over with immediate effect.
Diliani joined Nokia from Lucent Technologies in 2005 and has a long record both within the company – including positions in Africa and the US – and in the wider telecoms industry.
Diliani will be based in São Paulo, Brazil, where last April, TIM Brasil selected the vendor to roll out a 4G LTE network.
