NOS has started distributing Lleida.net registered electronic signature and notification services in Portugal. From now on, NOS will distribute in Portugal Lleida.net's registered services, such as the Certified SMS, the Certified Email and the Certified SMS Contract, which provide reliable proof of sending, receiving and processing data. As a result of its strategic alliance with the Spanish traded company, which was announced last September, NOS has become the first telecommunications company in the country to be included in the National List of Trusted Service Providers.

The Portuguese National Security Office (GNS) is responsible for this list. The services to be marketed by NOS are mainly aimed at the banking, insurance and energy industries, as well as at the public administrations, in a programme that is a pioneer in Portugal.
