• Universalization Targets

Anatel (Brazilian Regulatory Agency) Rules

These rules require that users should not have to walk

more than a certain distance to find a payphone

terminal, and also to find a reseller of pay phone cards .

Where is the best payphones placement?

• Management Tool: SAGRE TUP

This module manages the payphones placements,

assuring compliance with regulatory requirements.
