Will my SouthESIM have signal on Singapore's MRT (subway)?

Updated April 22, 2026

You'll be pleased to know that Singapore's public transport system is incredibly well-connected! Your SouthESIM will maintain a strong 4G or 5G signal throughout your journey on the MRT, even underground. This means you can comfortably browse, stream, or chat on WhatsApp without interruptions while traveling between stations like City Hall and Bugis. It’s perfect for planning your next stop or just catching up on messages during your commute.
