🇸🇬 Singapore eSIM

Before you go

• Singapore has some of the best mobile coverage anywhere. There are effectively no dead spots on the island, including the full length of the MRT underground.
• Changi Airport has excellent free Wi-Fi, so you can install or troubleshoot an eSIM on arrival if you didn't do it before flying. It's one of the few airports where that's a genuinely reliable fallback.
• The island is small enough that a short plan is often the right call. If Singapore is a stopover rather than the destination, look at a 3-day or 7-day plan instead of 30 days.
• These are data-only plans. They don't come with a local phone number, and they don't carry calls or texts, so keep your normal SIM switched on for those and let the eSIM handle data.
• The plan starts when it first connects to a network at your destination, not when you buy it. Buy it weeks ahead if you like; the clock starts when you land.
• Install it before you fly, over your home Wi-Fi. Installing needs an internet connection, which is the one thing you won't have at the airport.
• Don't delete an eSIM to make room for another one. An activation code only works once, and your phone can hold several profiles side by side.

Singapore eSIM questions

Does the eSIM work on the MRT and in the tunnels?

Yes. Singapore's underground rail network has full mobile coverage throughout, which is not true of most metro systems.

Will a Singapore plan cover Johor Bahru or Batam?

No. Those are Malaysia and Indonesia respectively, and a Singapore plan stops at the border. If you're crossing, an Asia regional plan usually costs less than two country plans.

How much data for a three-day stopover?

1 GB is plenty for three days of maps and messaging, especially with Wi-Fi widely available.
