Vivo Selects Oberthur Technologies to Enhance Network Efficiency

Over-The-Air Dynamic SIM Card Activation Platform

NANTERRE, France, March 22, 2011 - Oberthur Technologies, the world's second largest provider of security
and identification solutions and services based on smart card technologies,
has been selected by Vivo (BM&FBovespa: VIVO3, VIVO4; NYSE: VIV), the largest
mobile operator in Brazil, to manage the dynamic activation of SIM cards in
circulation through its remote activation platform, Smart HLR. Oberthur
Technologies relies on ATS to deploy Vivo's Platform.

Smart HLR detects first-time user registration and then allocates a
mobile number. This solution is of great support for mobile operators wishing
to reduce drastically SIM card logistics costs and to optimise their network:
no more need to stock pre-activated subscriber identification modules. In
addition to this, operators can offer their clients the possibility to choose
golden mobile numbers according to their preferences.

"This solution will help us ensure the availability of numbers, without
investing in additional retail infrastructure" said the group of Vivo's
Directors in charge of the project: Agenor Leao, Atila Branco, Fabio
Sepulvida, Gerardo Weiland, Katia Pedroso, Leonardo Capdeville and Patricia
Orn.

"In a more and more competitive environment, helping our customers
optimise the process of SIM ordering, distributing and provisioning is a top
priority and commitment for Oberthur Technologies'," said Martin Ferenczi,
Managing Director Americas, Card Systems Division at Oberthur Technologies.
Thus, Oberthur Technologies continually invests to innovate in the mobile
solutions arena. It is always a great sense of satisfaction when a major
client like Vivo renews its confidence in our expertise and competency."
