Telefônica Brasil S.A., operating as Vivo (VIVT3; VIV ADR), is moving forward with a strategic plan to gradually shut down its legacy 2G, 3G, and 4G networks, with the immediate priority focused on decommissioning 2G infrastructure to free up spectrum for its high-speed 5G rollout. This move is a direct effort to reduce the significant operational costs associated with maintaining three generations of redundant technology while accelerating the refarming of low-band spectrum for more efficient and broader 5G coverage across Brazil. The company’s focus on disciplined cost control and next-generation connectivity has been a key driver in its recent financial performance, with the company reporting double-digit EBITDA growth in its Q2 2026 results.
