eSIM Singapore: what you get

Networks
M1 5G, SingTel 5G, Starhub 4G
Speed
Up to 5G where the network has it, 4G elsewhere
Where your traffic comes out
Hong Kong or Singapore, depending on the plan. Websites see you there, wherever you actually are; streaming catalogues and apps that check your location go by that address.
After the daily allowance
A Daily Unlimited pass slows to 384 Kbps, 512 Kbps, or 1 Mbps until the next day. It is never cut off. How daily passes work
Top-ups
Add data to the same eSIM later, with no new QR code. A Daily Unlimited pass is bought for its full number of days and cannot be extended.
Buying ahead
Install any time within 180 days of purchase. For most plans the days start counting on the first connection at the destination, not at checkout.
Calls and SMS
Data only, with no phone number. Call over a messenger; a service that verifies you by SMS cannot reach this eSIM.

Singapore: signal everywhere, and two borders a short ride away

Singapore is a city covered from edge to edge, underground on the MRT included, so the questions are all at the edges. Johor Bahru, across the causeway, is Malaysia; Batam and Bintan, an hour by ferry, are Indonesia. A plan for Singapore stops at each of them. Near Woodlands and Kranji in the north a SIM left on automatic selection can attach to a Malaysian network and be billed for it; a prepaid eSIM for Singapore does not use those networks.

Depending on the plan, this eSIM's traffic comes out in Singapore or in Hong Kong — the table above lists both. It matters for one thing in particular: ChatGPT and Claude are offered in Singapore and not in Hong Kong, and on a connection that comes out there they take you for a visitor from Hong Kong and decline to open. Hotel or café Wi-Fi is the simple way round.

A tourist SIM at Changi costs from about ten Singapore dollars and is registered against your passport, three prepaid lines to a person at most. The eSIM saves the counter. It carries data only, with no Singapore number; Grab and Gojek both work with the account you already have.

Which plan for which trip

Messengers and maps are light. Video, calls and a laptop on a hotspot are what use data up.

How to install it

  1. 01

    Check your phone

    It has to take an eSIM and must not be locked to a carrier. Does your phone support eSIM?

  2. 02

    Scan the QR code

    After payment the QR code is on your order page. Scan it in the phone's settings — at home, over Wi-Fi.

  3. 03

    Switch it on when you land

    Turn on data roaming for the esimker line. It finds the network by itself.

Frequently asked questions

› Does it work in Johor Bahru, Batam or Bintan?

No. Those are Malaysia and Indonesia. For a day trip take a plan that names the country, or use Wi-Fi there.

› Why does ChatGPT say it is not available in my country?

Some plans send their traffic out through Hong Kong, where ChatGPT and Claude are not offered. On Wi-Fi in Singapore they open as usual.

› Is there signal underground on the MRT?

Yes. The stations and tunnels are covered, as is nearly all of the island.
