Best Travel eSIMs for Singaporeans (2026)

An eSIM lets you get mobile data overseas without swapping out your Singapore SIM or paying telco roaming rates. You install it before you fly and switch it on when you land. For Singaporean travellers heading to Japan, Korea, Thailand or anywhere else in the region, the right eSIM is usually far cheaper than Singtel, StarHub or M1 roaming. Below we compare the main options on price, coverage and ease of use, with all prices shown in SGD.

Frequently asked questions

Do eSIMs work on my phone in Singapore?
Most phones sold in Singapore in the last few years support eSIM, including recent iPhones (XS and newer) and flagship Android phones from Samsung, Google and others. Your phone also needs to be carrier-unlocked, which phones bought outright in Singapore almost always are.
Will an eSIM give me a phone number for calls and SMS?
Most travel eSIMs are data-only — they do not come with a local phone number. Your Singapore number stays active on your physical SIM for incoming calls and SMS (watch for roaming charges). For OTPs and messaging, use apps like WhatsApp or Telegram over data.
Should I buy an eSIM or just use telco roaming?
For short trips a Singtel, StarHub or M1 roaming pass can be convenient, but a travel eSIM is usually cheaper per GB, especially for longer stays or data-heavy use. The trade-off is that a data-only eSIM does not carry your phone number.
