How do you get a mobile phone number in Singapore in 2026?

Singtel, StarHub, M1 and SIMBA offer registered prepaid visitor products through their approved channels. A SIM (subscriber identity module) is the physical chip or service identity connecting a phone to a carrier. An eSIM (digital SIM profile) installs that identity on a compatible unlocked device without a removable card.

Under the current registration regime reflected by carrier guidance, a prepaid line registered with a foreign passport has a maximum 30-day validity. Singtel and M1 direct a customer who receives a Singapore-issued pass to re-register within that period to retain the number. SIMBA requires its stated service-centre or dealer route. Follow the exact carrier's deadline and channel because suspension can end the number.

Read the product features before paying. StarHub separately sells tourist products with a Singapore number, calls and texts, and data-only travel eSIMs with no Singapore number, calls or SMS. Singtel states that passport self-registration can initially provide data-only features until the required in-person step. A QR-delivered eSIM is only a format, not proof of voice, identity-text or number support.

Take the original passport and valid Employment Pass, S Pass, Dependant's Pass, Student's Pass or other carrier-accepted document. An Employment Pass is a work pass for qualifying foreign professionals. An S Pass is a work pass for qualifying skilled employees. A Dependant's Pass is a stay pass for eligible family members of certain work-pass holders. The FIN (Foreign Identification Number, the personal identifier assigned to eligible foreign pass holders) and name must match the carrier record.

Postpaid providers may also request a Singapore billing address, local payment method, remaining pass validity or a deposit. StarHub, for example, publishes six-month validity and address-document conditions for specified foreign-pass customers, while its assessment controls any deposit. No one checklist applies across every plan.

An MVNO (mobile virtual network operator using another carrier's network) can offer contract-free or lower-cost service. Check its foreign-document onboarding, support, eSIM availability, roaming, voice and SMS rather than assuming the host network gives identical terms.

Test calls, incoming SMS and data before leaving the shop. Confirm contract length, early cancellation, roaming, deposit return and whether handset finance is separate from service. A financed phone may continue billing after a plan change.

Number portability moves an eligible active Singapore number to another provider when names and identity records match. Start the port with the receiving provider and do not cancel first. Before departure, settle final bills, cancel through the official channel or complete the port, and keep confirmation.

Exact name matching matters when a bank, Singpass (Singapore's government digital identity) or PayNow (bank transfer service using a mobile number, national ID or other registered proxy) checks control of the number. A line can receive ordinary SMS yet still fail a particular bank or identity flow. Update the bank and PayNow before surrendering a number, and never let a seller register your SIM under another person's identity.
