Singtel, StarHub, M1 and SIMBA roaming: what it costs abroad and how to pay less

Before every trip the same question comes up: do I add my carrier's roaming plan, or get a travel eSIM? In Singapore the answer depends more on your carrier than anywhere else. Some plans are hard to beat in Malaysia and the region; others get expensive the further you go.

We read the prices on the official sites of Singtel, StarHub, M1 and SIMBA on 20 October 2026. Offers change often, so check again before you fly.

What to know first

• Your plan may already include roaming. SIMBA plans come with roaming data for Malaysia, Indonesia, Hong Kong, Thailand and more, and some Singtel plans include Roam Asia or Roam Worldwide. Check your plan before buying anything.
• Singtel turns on a plan for you. AutoReadyRoam activates the cheapest ReadyRoam pack when you start roaming, and it cannot be removed. It protects you from pay-per-use rates, but it also means you pay as soon as you roam.
• M1's $0.99 day pass is for Bespoke plans only, and the price is promotional for the first 12 months, then $2.99.

When an eSIM makes sense

Wigoo's prices are not written here: they come from the catalog when you read this, in your currency. The calculator puts them next to your carrier's plans.

• On longer trips beyond Asia, where Singtel and StarHub plans cost more per GB: try Europe or the US in the calculator.
• In SIMBA's Group B, C and D destinations, which are not in any allowance.
• When your carrier's day pass runs every day of a two-week trip: a prepaid plan has a price you know before you leave.
• Your Singapore number stays on, in the phone, for calls and OTPs, without data roaming on that line.

In Malaysia, Indonesia and Thailand, Singtel's ReadyRoam Neighbours and M1's day pass are hard to beat. Check the numbers for your own trip above.
