Looking for the best prepaid plan in Singapore? A prepaid SIM card gives you total control with zero commitment: pay upfront, use what you've loaded, and there's no contract, no monthly bill and no credit check. Prepaid suits tourists and short-term visitors, foreign workers, kids' first phones, backup numbers and anyone who simply wants a hard cap on spending. The grid below compares every prepaid plan so you can weigh up price, data and validity in one place.
Who sells prepaid SIM cards in Singapore?
Classic top-up prepaid comes from the three network operators:
Singtel (including its
hi! brand),
StarHub (including
heya) and
M1. Alongside them, a wave of app-first brands —
eight,
Maxx,
CMLink and
Changi Mobile — offer pay-upfront, cancel-anytime plans that behave like prepaid without the top-up ritual. One common confusion:
GOMO and
SIMBA are frequently searched as "prepaid", but their plans are actually no-contract postpaid — you get a monthly bill, just with no lock-in.
Validity, top-ups and long-validity SIMs
Prepaid value hinges on validity as much as price. Short-validity packs suit a two-week trip; if you top up rarely — a standby phone, a number you keep for banking OTPs — look for long-validity options such as 180-day or 365-day packs so your credit and number don't lapse between top-ups. The grid lists validity for every prepaid plan, so check that column before you buy.
The rules worth knowing
All Singapore SIMs must be registered with ID, and IMDA caps prepaid at
three prepaid SIM cards per person in total, across all operators combined. Tourists can register with a passport, and many brands now sell prepaid
eSIMs you can activate before you even land. If you use your phone heavily every month, a
postpaid plan or a flexible
no-contract plan usually delivers more data per dollar — compare against our
cheapest plans before committing. Otherwise, use the filters above to sort prepaid plans by data and price and pick your top-up.
