Best eSIM for Singapore 2026: Marina Bay to Sentosa
Singapore: the easiest country for connectivity
Singapore might be the simplest place on earth to stay connected. The island is small, densely populated, and blanketed with fast 4G and 5G. Signal is excellent literally everywhere, including the MRT underground, inside malls, and on Sentosa. You will never have a connectivity problem here.
Why you still need data
Free public Wi-Fi exists but requires registration and is slow. Your eSIM gives you instant, fast, private connectivity. Grab for taxis. Google Maps for navigating the underground mall labyrinths. Burpple for food recommendations. And the most important use: finding which specific stall in which specific hawker centre serves the thing that someone told you about.
How much data
Singapore is a small country and most visits are short. Three to five days typically uses 2 to 4 GB. Even a full week rarely exceeds 5 GB unless you are streaming video constantly. The smallest plan available will likely be more than enough.
