0–6 hours
Use airport Wi-Fi; confirm the exact address and contact; take MRT with light luggage, or compare taxi/PHV for late-night, family, or heavy-luggage arrivals; buy only 1–3 days of data if needed.
Relocation / First 72 hours
First 72 hours in Singapore: SIM, transport, food and arrival budget
Arrival overspending usually comes from stacking small rushed decisions: the wrong SIM, an unnecessary taxi, duplicate transit products, and three days of convenience-store meals. Secure data, movement, food and sleep first; defer long-term plans until your address and local documents are stable.
Run the first 72 hours in blocks
6–24 hours
Test one reliable bus/MRT payment method; eat one normal hawker or coffeeshop meal; buy water, breakfast and basics; record actual spend.
24–72 hours
Test the real home-to-work/school commute; compare longer-term prepaid/postpaid options; locate a supermarket, clinic and wet-weather route; then choose apps.
Four decisions to make first
| Decision | Option | Best for | Watch-out |
|---|---|---|---|
| Airport transfer | MRT / public transport | Daytime, light luggage, budget-first | Check the last train and transfers; avoid a multi-change trip with large cases. |
| Airport transfer | Taxi / PHV | Late arrival, children, 3–4 travellers, heavy luggage | Changi currently quotes S$25–45 by taxi to the city, before airport and peak/midnight surcharges. |
| Transit payment | Foreign Visa/Mastercard | Fast setup or short stay | SimplyGo currently charges S$0.60 per day of use for foreign Mastercard/Visa; use the same physical card or wallet for entry and exit. |
| Local number | Short prepaid / eSIM | OTP, maps and immediate contact | Bring original ID, confirm eSIM support, and never register a SIM for someone else. |
72-hour starter budget
| Airport transfer | S$2–45+ | MRT versus taxi/PHV is the largest variable |
| 1–3 days of data | S$5–20 | Buy a bridge plan before a long-term decision |
| First-day meals and water | S$15–35 | Hawker/coffeeshop versus airport or mall dining |
| Basic supplies | S$20–50 | Water, breakfast, toiletries, adapter if needed |
| 72-hour total | S$45–150+ | Excludes accommodation, deposit, furniture and attractions |
Airport-exit checklist
- Save the address, check-in method and host contact offline.
- Carry one physical payment card and some Singapore-dollar cash as backup.
- Test transit with one card; do not tap a wallet full of cards.
- Buy SIM service only from an operator or authorised retailer and register it yourself.
- Choose long-term mobile, banking and broadband after day three.

FAQ
Must I buy a SIM at Changi Airport?
No. Use airport Wi-Fi to reach your host and compare a short prepaid/eSIM bridge with longer-term options after check-in. Pay airport convenience pricing only when an immediate local number is genuinely useful.
Can I tap a foreign bank card on MRT?
Supported foreign contactless cards can work, but your bank may add overseas charges and SimplyGo currently adds S$0.60 per day for foreign Mastercard/Visa use. Test once and keep a backup.
