Best eSIM for Singapore in 2026: unlimited data, real prices and what to check
Key facts
- VoaSim's Singapore eSIM costs USD 18.90 for 5 days and USD 61.90 for 30 days, with truly unlimited data and no throttling.
- The eSIM connects automatically to local networks such as Singtel, StarHub and M1 on 4G and, where available, 5G.
- Your days start counting at the first connection in Singapore, so install at home and keep the line off until you land.
- It is data-only: you keep your own number for WhatsApp, but you get no Singaporean phone number for local SMS or voice.
- For very light data use or very long stays, a per-GB plan or a local prepaid SIM can be the cheaper choice.
See the exact price for your dates
Singapore is one of the easiest places in the world to stay online. Coverage is dense across the whole city-state, from Changi to Sentosa, and almost every traveler lands with a phone that already supports eSIM. The real question is not if an eSIM works — it's which type of plan fits your trip.
This page lays out what VoaSim costs for Singapore, how it compares with per-GB brands and carrier roaming, and the cases where another option is honestly the smarter buy.
How much a Singapore eSIM costs with VoaSim
VoaSim charges one price per duration, identical for every destination. Singapore costs the same as Japan, Spain or Brazil. Prices below already include today's 15% promo, and data is unlimited on every line.
| Duration | Price (USD) | Per day |
|---|---|---|
| 5 days | 18.90 | 3.78 |
| 7 days | 23.90 | 3.41 |
| 10 days | 30.90 | 3.09 |
| 15 days | 42.90 | 2.86 |
| 30 days | 61.90 | 2.06 |
| 60 days | 106.90 | 1.78 |
Trips of 1 to 4 days pay the 5-day package. A second eSIM in the same order gets 10% extra off, which helps couples and families. Maximum is 90 days per eSIM. Run your exact dates through the price simulator to see the final number before you pay.
Which networks you connect to in Singapore
The eSIM is not tied to a single operator. On arrival your phone picks up a local partner network automatically — in Singapore that means the major mobile operators Singtel, StarHub and M1. Connection is on 4G and, where available, 5G.
Because Singapore is a city-state, coverage is uniform: Changi Airport, the MRT, Marina Bay, Orchard Road, Sentosa, Jurong and the ferry terminals are all inside the same dense network footprint. There is no "rural dead zone" problem to plan around.
One practical note: this is a data-only eSIM. You keep your own number on your physical SIM, so WhatsApp, Telegram, iMessage and app calls keep working over data. What you don't get is a Singaporean phone number for traditional voice calls or local SMS codes — if a delivery app or a bank needs an SG number, a local SIM is the tool for that job.
Unlimited vs per-GB: which one fits your trip
Most eSIM brands sell Singapore by the gigabyte. Airalo, Nomad, Saily, Ubigi, Yesim, GigSky, Alosim, Jetpac, Maya Mobile and others let you buy a small bundle through their app, which is genuinely cheaper if you barely use data. Holafly sells "unlimited" plans with usage conditions written into its terms. Always read the cap, the validity window and the tethering rules on each brand's own site.
A simple way to decide:
- Light user — hotel Wi-Fi, maps a few times a day, some messaging: a 1–3 GB package will probably do, and it can cost less than an unlimited plan.
- Normal tourist — maps all day, ride-hailing, photos and video uploads, a few video calls home: unlimited removes the counting.
- Heavy user or remote worker — tethering aside, streaming, cloud backups, long calls: unlimited with no throttling clause is the safer bet.
VoaSim's pitch is narrow and honest: no data cap, no speed reduction, no hidden fair-use policy. If you never use more than 2 GB a week, you may not need that.

eSIM, carrier roaming or a local SIM in Singapore
Three realistic routes into the Singapore network, side by side:
| Travel eSIM | Carrier roaming | Local SIM | |
|---|---|---|---|
| Setup | QR by email, install at home | Enable in your carrier app | Shop or airport counter |
| Keeps your number | Yes | Yes | No — SIM comes out |
| Local number | No | No | Yes |
| Cost model | Flat per duration | Per day or bundled | Prepaid pack |
Roaming from T-Mobile, AT&T, Verizon, EE, Vodafone, Telstra, Rogers or Google Fi is convenient and sometimes already included in your plan — check the current rate for Singapore in your carrier app before assuming anything, and note that many plans slow you down after a daily allowance. See our roaming overview.
A local prepaid SIM is the best pick for long stays, and if you need an SG number for local services. It costs airport time and usually passport registration. VoaSim does not sell physical SIM cards.
Installing before you fly (and when the clock starts)
Buy, then install at home on Wi-Fi. The QR code lands in your inbox within minutes, with a step-by-step guide for iPhone and Android, and a WhatsApp heads-up if you left a number at checkout.
The important rule: your days start counting at the first connection to a network at the destination, not at purchase. So install the profile, then leave the eSIM line switched off until you land in Singapore. On Android, make sure you don't turn on the eSIM's mobile data before the trip.
Landing routine at Changi:
- Turn off data roaming on your home carrier line.
- Switch the VoaSim line on and set it as the data line.
- Give it a minute to register on a local network.
If nothing happens, the free eSIM Rescue tool diagnoses an eSIM of any brand with no signal. Human support answers at hola@voasim.com or on-site chat. If the eSIM will not connect and support cannot fix it, you get a 100% refund.
Phone compatibility and payment
eSIM works on iPhone XR or newer, Samsung Galaxy S20 or newer, Google Pixel 3 or newer and most phones released from 2020 on. Universal check: dial *#06# — if an EID number appears, your phone supports eSIM. A carrier-locked phone has to be unlocked first, which your home operator does.
Payment is by international credit or debit card in USD through Stripe. No hidden fees, no local-currency billing, no cash. The invoice arrives by email.
Adding Malaysia, Thailand, Indonesia or Japan to the same trip? Coverage spans 170 destinations worldwide at the same flat price per duration, so one eSIM often carries the whole route — check your countries on the destinations page or compare options in our best eSIM guides. On hotspot/tethering, we don't promise it: it depends on the plan, so confirm with support before relying on it.
Why trust VoaSim?
Registered company with an invoice on every purchase, USD payment via Stripe with no hidden fees, human support and a guarantee: if the eSIM will not connect and support cannot fix it, you get 100% back.
