Singapore has emerged as one of Asia’s most popular destinations, with the Singapore Tourism Board recording 11.6 million international visitors in the first eight months of 2025 alone, representing a 2.7% increase from the previous year. As connectivity becomes increasingly essential for modern travelers, choosing between eSIM technology and WiFi for your Singapore trip can significantly impact your travel experience and budget.
Understanding eSIM vs WiFi
What is eSIM Technology?
An eSIM (embedded SIM) is a revolutionary digital SIM card built directly into your smartphone, eliminating the need for physical SIM cards. This cutting-edge technology allows travelers to download mobile plans instantly through a simple QR code scan, providing immediate connectivity upon arrival in Singapore.
In 2025, over half of smartphones worldwide are now eSIM compatible, making this technology increasingly accessible to international travelers. Compatible devices include:
- Apple iPhones: iPhone XR and all newer models, including the latest iPhone 17 series
- Samsung Galaxy: Galaxy S20 and newer models, including the S25 series, Z Fold, and Z Flip series
- Google Pixel: Pixel 3 and newer models
- Other Android brands: Many flagship and mid-range devices from Oppo, Xiaomi, and other manufacturers
The technology supports multiple carrier profiles simultaneously, with modern devices like the iPhone 13 series accommodating two eSIMs at once, providing exceptional flexibility for international travel.
WiFi in Singapore
Singapore offers extensive WiFi infrastructure across the city-state, from Changi Airport’s complimentary service to widespread public hotspots. Changi Airport provides unlimited free WiFi with 3-hour sessions, requiring users to reconnect after each period. The airport’s WiFiChangi network can handle over 2.3 million devices monthly, with approximately 5,000 devices connected simultaneously.
Public WiFi is available throughout Singapore in shopping malls, cafes, restaurants, and tourist attractions. However, these networks often come with limitations including security concerns, inconsistent speeds, and restricted access areas.
