Best Mobile Plans in Singapore

Singapore lets you keep your mobile number when you change operator. You apply with your new provider, not your old one: they will ask for your number and ID and arrange the transfer, which is usually done within a few working days (your new provider confirms the date). Keep your old line active until the port finishes, and check any contract early-termination charge or unpaid bill first.

Postpaid plans bill you monthly for a fixed bundle of data, calls and SMS, and often run on a contract. Prepaid plans are paid up front: you buy a pack or top up credit, with no monthly bill and usually no contract. Postpaid tends to give more data per dollar for regular use; prepaid suits light users, visitors and anyone who wants flexibility.

Plans with a contract, especially those bundled with a phone or a promotion, usually carry an early-termination fee. SIM-only and no-contract plans normally do not. The contract length is shown on every plan card, but always read the provider's terms before you sign.

Many recent phones support eSIM, and several providers offer it for new lines. Check that your phone is unlocked and eSIM-capable, then ask the provider for eSIM activation. Search PlanSifu for 'eSIM' to find plans that mention it.

Automatically, from the prices and specs we collect from provider websites every night: for example price per GB, speed or contract terms. Plans limited to an age group are left out of the headline picks. We may earn a commission if you apply through our links, but that does not change the ranking.
