Best Prepaid 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.

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.
