Case Study: China Unicom Shanghai Branch achieves 24/7 on-call support and 50%+ efficiency gains with TeamViewer Tensor (TeamViewer)

Leading telecommunications provider streamlines work efficiency and improves level of service for customers and staff

China Unicom Shanghai Branch’s Wireless Network Operations Center, responsible for planning, operating and optimizing the branch’s wireless network, faced a surge in remote work and data demand during COVID‑19. Corporate security policies blocked access to internal systems from home and auditors couldn’t log in on weekends or holidays, creating delays in order dispatching and a need for a secure, mobile remote‑access solution to cut response times.

TeamViewer Tensor provided secure remote connectivity (4096‑bit RSA key exchange, AES‑256 encryption) with strict conditional access, mobile support and unattended‑computer control, enabling 24/7 on‑call operations and private cloud–style account management. The deployment preserved compliance, sped up cross‑department issue resolution and mobile dispatching, shortened response times and improved workflow efficiency by more than 50%.
