eSIM data plans for Singapore

Two ways to buy data here: a fixed amount that lasts up to 30 days, or a daily unlimited allowance sold in blocks from a single day to a month.

Fixed data plans

Sizes run from 1GB for a week up to 50GB for a month, on M1 or SingTel. These suit a traveller who has a rough sense of how much they use, or who wants to spend little on a short visit. If the data runs out before the trip does, a top-up on the same eSIM restores it, so a smaller size still leaves room to add more if the days get busier than planned.

Unlimited by day

Sold in day counts from 1 to 30, on SIMBA, SingTel or Star Hub, these suit a traveller who wants one flat rate per day rather than a gigabyte total to watch. Each plan carries a fair use policy: past a daily amount of use, speed is reduced for the rest of that day.

When to install

Validity begins the first time the eSIM connects to a network in Singapore, not at the moment of purchase or installation. It can be installed before departure and left alone until landing, without losing any of its validity window.

Choosing between them

A short visit with light use suits a small fixed data plan, with a top-up on hand if needed. A trip with steady daily use, or one where the exact length is not fixed yet, suits the unlimited-by-day option matched to the number of days planned. Hotspot and tethering work on every plan here, fixed data and unlimited alike, so either choice can share its connection with a laptop or another phone.
