About this network

CTM-MO is Companhia de Telecomunicações de Macau (CTM), the incumbent telecom operator of the Macau Special Administrative Region.

What it's used for

• Fixed broadband, mobile, and business connectivity for customers across Macau. This is the territory's main "eyeball" network, so most Macau residential traffic originates here.

Notable

• CTM was Macau's sole telecom concessionaire for decades before liberalisation, and it remains the dominant operator by subscribers.
• With a few hundred thousand addresses for a small, dense territory, the footprint is large relative to Macau's population.
