Telco & utilities setup (category guide)

New arrivals hit the same sequence: travel or prepaid SIM on passport → stable Singapore number → Singpass → postpaid/eSIM once FIN and MyInfo clear. IPA alone often fails for long-term contracts; keep topping up prepaid and port later. Photograph meters on key collection, confirm whether the landlord keeps utility accounts, and book fibre with an access window. Basement carparks and older walk-ups vary by network — ask neighbours, not just the mall kiosk. Once the Singapore number is live, install ScamShield and treat bank/police WhatsApp threads as hostile until verified in official apps — FIN holders are frequent phishing targets. Pair this entity with the utilities-telecom and scams-Singpass guides for the full chicken-and-egg playbook. A working Singapore number is also KYC fuel for bank onboarding — keep the prepaid/postpaid paperwork that proves the number is yours when salary-account applications ask for local contact evidence. Family ops note: dual-career PH coverage and orientation SMS alerts both need working local SIMs on both phones — do not leave one parent on roaming WhatsApp only.
