Singapore SIM/eSIM and Internet Setup for New Arrivals

Phone setup gates everything: rental viewings, OTPs, navigation, banking, and everyday admin. This page is a first-week playbook: get online first, optimise later.

Make one decision first: prepaid or SIM-only

If you don’t have a FIN or stable local address yet, start with prepaid (or a tourist eSIM) to unlock data + OTPs. Move to a SIM-only plan once your documents are settled.

Option Best for Budget range Note
Prepaid / tourist eSIM Just arrived, documents pending, immediate data + OTPs ~S$8–30 per 28–30 days (varies by promo) Validity, re-registration needs, and real-world coverage matter more than headline data.
SIM-only (no contract / short contract) FIN/pass ready; staying longer-term ~S$10–80/month (wide range by tier) Better long-term stability; test coverage before porting your main number.
Home broadband (later) Once your rental is stable; reliable home connection ~S$30–60/month (depends on contract/promos) Check installation approval, contract length vs lease, and appointment timing.

What to bring (shop or online)

  • Passport + (if available) a valid pass / FIN details.
  • Your old number to keep receiving key OTPs temporarily.
  • Unlocked phone + eSIM compatibility (if you want eSIM).
  • A usable card for online sign-up, or some cash for retail purchase.
  • A temporary address (hotel/short stay) for registration and delivery.

First-week workflow (safe and boring, but works)

  • Day 0-1: buy a prepaid SIM or tourist eSIM so you have data + OTP access.
  • Day 1-3: test signal at the places you actually use (home/work/MRT). Don’t port your main number yet if coverage is bad.
  • After you get a FIN / pass: switch to SIM-only for long-term value and easier renewals.
  • Final step: migrate 2FA/OTP numbers to your long-term line, and keep the old number as a backup for a while.

Watch-outs

  • Passport-registered prepaid SIMs may only be valid for 30 days; keeping the number can require updating/re-registering with a Singapore-issued ID in time.
  • There can be limits on how many prepaid SIMs one ID can register—avoid opening multiple “backup” SIMs too early.
  • Huge data allowances don’t guarantee indoor coverage; test basements, older buildings, and MRT interchanges.
  • Check add-ons like caller ID, roaming, and IDD. Don’t overpay for features you won’t use monthly.
