The coverage includes all six underground lines as well as 27 stations of the newly-completed Thomson-East Coast Line (TEL).
Singtel implemented the 5G coverage in early 2022, deploying a team of specialised engineers carrying out the network upgrades.
Singtel engineers had to work within constraints such as conducting testing and installation works during stations’ non-operational hours to avoid disruption to train services.

They had to work within confined spaces, which require specific tools and precise and safe execution.
In keeping with Singtel’s goal of achieving net zero by 2045, its engineers reconfigured existing hardware that originally served the 3G and 4G spectrums within the MRT tunnels to 5G.
“Whether traveling above or below ground, our customers can rely on our strong connectivity to work on-the-go, keep in touch with their loved ones, surf the internet, stream videos or game on their mobile devices,” stated Singtel CEO Ng Tian Chong.
“We’re proud to have achieved this new milestone, demonstrating our commitment to delivering the best connectivity in Singapore.”
The 5G implementation across MRT lines brings Singtel’s 5G coverage to over 1,700 outdoor and 1,000 indoor locations including all shopping malls and transport hubs along the MRT.
Singtel has been deploying 5G network for consumers since 2020.
Singtel deployed 5G to support connectivity in VivoCity. In 2021, it achieved two-thirds nationwide coverage in 2021.
In 2022, it reached 95% network coverage ahead of the IMDA regulatory requirements of 5G coverage by the end of 2025, Hardware Zone reported.
