eSIM vs local SIM in Singapore
Both options give you local data in Singapore, but they work differently. The right choice depends on how you travel and how much setup friction you can tolerate.
| Factor | Travel eSIM | Local SIM card |
|---|---|---|
| Price (7 days, 5 GB) | $1.1 | $12 avg |
| Where to buy | Online, before you leave | Airport, store, or online |
| Activation time | Under 2 minutes | 5 – 60 minutes |
| Passport required | No | Yes (mandatory) |
| Phone number included | Data only | Yes, local number |
| Hotspot tethering | Yes (HelloRoam, Saily) | Yes (most plans) |
| Works on dual SIM | Yes, alongside home SIM | Replaces your home SIM |
| 5G access | Yes (HelloRoam) | Varies by local carrier |
Verdict: An eSIM costs less than a local SIM for a typical 7-day trip to Singapore and activates before you land. It is the faster, lower-friction option for most travelers. Local SIM registration in Singapore requires a passport, adding 15 to 60 minutes at the point of purchase. eSIMs skip this entirely.

How to set up an eSIM in Singapore
eSIM activation works the same way across all carriers. The process takes under 5 minutes on a compatible phone.
Confirm eSIM compatibility
Your phone must support eSIM. Most phones released after 2020 do, including iPhone XS and later, Samsung Galaxy S20 and later, and Google Pixel 3 and later. Check Settings for an eSIM or digital SIM option.
Check your phone is carrier-unlocked
Some carriers lock phones to their network. If you bought your phone on contract or from a carrier store, contact them to unlock it before your trip. eSIMs from third-party providers will not work on a locked device.
Purchase your Singapore eSIM plan 1-30 days before your trip
Buy from HelloRoam, Airalo, Holafly, or another provider listed above. You can purchase 1 to 30 days before departure. Choose a plan that covers your intended stay. You receive a QR code by email within minutes of purchase.
Scan the QR code
Go to Settings > Mobile / Cellular > Add eSIM (or Add Data Plan). Point your camera at the QR code. The eSIM profile installs in about 60 seconds.
Activate on arrival in Singapore
Most plans activate when you land. Set the eSIM as your primary data line in Settings. Turn off data roaming on your home SIM to avoid unexpected charges. Run a speed test to confirm you are connected.
eSIM notes for Singapore
Singapore has three carriers: Singtel (largest), StarHub, and M1. All three have 5G. Changi Airport Terminals 1-4 have SIM vending machines and carrier counters. Registration requires passport scanning at the machine. Singapore is a common layover or starting point for Southeast Asian travel.
Singapore has no meaningful dead zones for any of the three carriers. The MRT North-South Line, East-West Line, and Circle Line all have 4G throughout, including between stations underground. Marina Bay Sands area, Sentosa Island, Gardens by the Bay, and Jurong East all get 100+ Mbps 4G. Even the reservoir parks like MacRitchie have signal throughout the trails. The only genuine weak spots are a handful of construction tunnels and the interior of some older shophouses with thick concrete walls. For all practical tourist purposes, Singapore connectivity is flawless.
Local SIM vending machines at Changi are fast and cheap. eSIM is the better pick for travelers combining Singapore with Malaysia or Indonesia who want one plan covering the region.
Things to know before you buy
- Travel eSIMs in Singapore are data-only. Voice calls and SMS go through your home SIM or a VoIP app like WhatsApp.
- eSIM plans do not include a local Singapore phone number. If you need to call local numbers (hotels, taxi companies), use a VoIP app or buy a physical local SIM.
- 5G is available in Singapore's major cities. HelloRoam includes 5G access in all plans at no extra charge. Other providers may throttle to 4G LTE.
- Most international eSIM providers do not support calls or SMS in Singapore. Keep your home SIM active in dual-SIM mode for those functions.
