Best eSIM for Singapore: four brands compared
For most trips to Singapore the best eSIM is a fixed data plan, and when we checked on 1 November 2026 RoamMore's 5GB and 10GB plans for 30 days cost less than the same plans from Airalo and Nomad. Our Endless plan also cost less for a week than any unlimited week we found at 3GB a day.
10GB for 30 days: RoamMore US$12.10, Airalo US$16, Nomad US$14. 5GB for 30 days: RoamMore US$7.20, Airalo US$10, Nomad US$9.
RoamMore wrote this page and sells eSIMs for Singapore, so read it with that in mind. Every fixed plan price below was read on the brand's own Singapore page on 1 November 2026, in US dollars, and links back to that page. The unlimited prices were read on 15 October 2026 for our guide to the best unlimited eSIM for Singapore, and link back the same way. Our prices come from our live catalogue and change when it does. If you spot a mistake, email [email protected] and we will fix it.
How do the Singapore eSIMs compare on price?
Fixed data plans
| Brand | 5GB, 30 days | 10GB, 30 days |
|---|---|---|
| RoamMore with SPRING35 | ||
| Airalo | US$10 | US$16 |
| Nomad | US$9 | US$14, a sale price |
All of these are data only. Holafly does not sell fixed data plans for Singapore.
Unlimited plans
| Brand | Unlimited, 7 days | Unlimited, about two weeks | Full speed a day on unlimited |
|---|---|---|---|
| RoamMore with SPRING35 | Endless: | 15 days: | You choose. At 1GB to 3GB a day, then 1 Mbps |
| Airalo | US$27 | 15 days: US$48 | 3GB, then 1 Mbps |
| Holafly | US$27.50 | 15 days: US$51.50 | No daily amount stated |
| Nomad | No 7 day plan. 5 days: US$18 | Not sold. 10 days: US$27 | 2GB, then 1 Mbps |
The fixed plans are like for like: the same amount of data for the same 30 days. The unlimited plans are not. Each brand gives a different amount of full speed data a day, so compare the price at the daily amount you will really use, not the word unlimited. A sale price can end at any time.
Which networks will you use in Singapore, and is there 5G?
Our Singapore plans run on M1 and SingTel, both with 5G, so your phone has a second network to fall back on. The Singapore page lists every plan with its networks and speed.
5G needs a phone that supports it. Where there is no 5G, the eSIM uses 4G.
How much data do you need for a week in Singapore?
These are the daily amounts our plan finder uses. Not sure? Most people are Standard.
| Your use | A day | One week | Two weeks |
|---|---|---|---|
| Lite | 300MB | 2.1GB | 4.2GB |
| Standard | 1GB | 7GB | 14GB |
| Heavy | 2GB | 14GB | 28GB |
So a 10GB plan covers a week of Standard use in Singapore with room to spare, and a fortnight at that rate needs a bigger plan or a top up. Our cost and data guide breaks the figures down by app.
Should you get unlimited data or a fixed plan in Singapore?
A fixed plan is usually the cheaper buy if you know roughly how much you use, because one allowance stretches across light days and busy ones. Unlimited is the simpler buy if you stream, make long video calls or would rather not watch a meter.
If you do want unlimited, compare plans at the same daily amount. For Singapore:
- At 1GB a day, Endless is US$8.90 for a week, less than any unlimited week in the table, though each of those gives you more full speed data a day.
- At 2GB a day, Endless is US$12 for 5 days, less than Nomad's US$18 at the same daily amount, and US$21.30 for 10 days, less than Nomad's US$27.
- At 3GB a day, Endless is US$23.70 for a week, less than Airalo's US$27 and Holafly's US$27.50. For 15 days at 3GB a day, Endless is US$47, less than Airalo's US$48 and Holafly's US$51.50.
Endless charges one price for the exact number of days you pick, so a 12 day trip is priced for 12 days, not the nearest pack. Our guide to the best unlimited eSIM for Singapore compares every daily amount in more detail.
When do the days start?
Our Singapore plans start when the eSIM first connects to a network in Singapore, so you can install it at home and it waits. The one exception is a 100MB trial, which starts when you install it, and the Singapore page marks it. Endless also starts on first connection there, and its full speed amount refills every 24 hours from that moment.
Can you use a Singapore eSIM as a hotspot?
On every RoamMore plan, yes: sharing your connection works. What you share counts toward the plan's data, and on the daily plans and Endless toward the day's full speed amount. If you plan to work from a laptop on another brand's plan, check its hotspot rules before you buy.
What should you do before you fly from New Zealand or Australia?
Install the eSIM at home on wifi a few days before you leave, and leave it switched off. When you land at Changi, switch it on, set it as your data line and turn on data roaming for it. Keep your home SIM on for calls and texts, with its own data roaming off, so your carrier does not charge you for data. Our landing day checklist walks through each step.
Our prices are in US dollars, so your bank converts the payment.
When is another brand the better choice?
- You want minutes and texts on the eSIM. Ours are data only; check the other brands' Singapore pages for plans that include them.
- You use more than 3GB a day. Holafly states no daily amount, and its week at US$27.50 costs less than Endless at 5GB a day, US$48.20.
Choose RoamMore if you want a fixed plan at the lowest price we found, two 5G networks, no app to install, and a real person who answers by email or WhatsApp.
How did we check these prices?
We read every fixed plan price on 1 November 2026 on the brand's own Singapore page, in US dollars (Airalo with its own currency setting), with no codes, credits or memberships, and the unlimited prices the same way on 15 October 2026. We did not go through any checkout. Prices change, so each one links to the page it came from, and we check them again each month.

Questions travellers ask
What is the best eSIM for Singapore?
For most trips, a fixed data plan. On 1 November 2026, RoamMore's 5GB and 10GB plans for 30 days cost less than the same plans from Airalo and Nomad, and Holafly sold unlimited plans only. For a week of unlimited data at 3GB a day, our Endless plan cost less than any unlimited week we found. RoamMore wrote this answer, and every rival price on the page links to the store it came from.
Which networks does a Singapore eSIM use?
Ours list M1 and SingTel, both with 5G. Each brand lists its own networks on its Singapore page.
Is 10GB enough for a week in Singapore?
For most people, yes. At Standard use, about 1GB a day, a week comes to about 7GB, so a 10GB plan leaves room to spare. Two weeks at that rate needs more than 10GB, so pick a bigger plan or top up.
