Best eSIM for Singapore from Australia

37 plans from 4 providers, priced in Australian dollars and ranked by cost per GB.

The cheapest Singapore eSIM we list is Ubigi's 3 GB plan for 15 days at A$10.00 (A$3.33/GB). The most data for the money is Airalo's 50 GB plan for 30 days at A$70.00 (A$1.40/GB), and our best-network pick is Ubigi's 25 GB plan for 30 days at A$38.00 (A$1.52/GB). The plans we list name Singtel, StarHub, M1 or Simba.

How much data will I need?

As a rough guide from Telstra's figures, an hour a day of browsing and email uses about 0.1–0.5 GB over 7 days and 0.2–1.1 GB over 14 days, and an hour a day of standard-definition video adds about 4.9 GB and 9.8 GB. Source: Telstra

Cost per GB is price ÷ data; unlimited plans show price per day. Airalo unlimited (3, 5, 7, 10, 15 and 30 days): slows to 1 Mbps after 3 GB a day. Holafly unlimited (3, 5, 7, 10, 15 and 30 days): may slow speeds for up to a day under its fair-use policy; no threshold or speed is stated. Ubigi unlimited (2 days): slows to 2 Mbps after 10 GB. Ubigi unlimited (7 days): slows to 2 Mbps after 20 GB. Ubigi unlimited (15 days): slows to 2 Mbps after 30 GB. Ubigi unlimited (30 days): slows to 2 Mbps after 60 GB.

The table lists plans of 30 days or less. Holafly and Simify also sell longer Singapore plans.

Using an eSIM in Singapore

Four networks, one coverage standard

IMDA's quality-of-service results for April to June 2026 tabulate four mobile operators: M1, Singtel Mobile, StarHub Mobile and SIMBA (Simba in the plan tables). Under its 4G framework IMDA requires each of them to cover more than 99% of Singapore outdoors, measured as a signal of at least -109 dBm. The results page does not publish an outdoor coverage percentage for each operator, so it does not rank the four on outdoor coverage.

In the same period M1, Singtel Mobile and SIMBA passed all 60 buildings IMDA tested for in-building coverage, and StarHub Mobile passed 58 of the 60. In IMDA's tunnel survey for the same quarter, all four passed every road and MRT tunnel except the Downtown Line, where StarHub did not meet the 99% standard; IMDA says coverage there is being improved. IMDA notes that your own experience can differ with your handset, its settings and how many people are nearby. The plan page names which operator a travel eSIM uses. We do not rank one operator first for Singapore, because IMDA's published results do not.

Registering a tourist SIM

Singtel's hi! Tourist page says the plan is for foreign passport holders only. A SIM registered with a passport gets data-only features and is valid for 30 days. To keep it longer you re-register with a Singpass or Singapore-issued ID within that window, and calls and texts are switched on in person at a selected Singtel hi! retailer with your passport. Singtel says this 30-day limit comes from IMDA's regulations, in force since 15 July 2024.

M1's FAQ says you must register its Tourist SIM on purchase, with a passport or work permit, and that it is valid for 30 days from registration. It says each ID can register up to three Tourist SIMs with calls and SMS, which fits IMDA's limit of three prepaid SIM cards per subscriber, in place since 2014.

The 30-day and three-SIM limits apply to SIMs from Singapore's operators; we have not found IMDA's own page on the 30-day rule. We have not confirmed whether either applies to a travel eSIM bought from an overseas provider. Check the plan page for any ID step before you buy.

Local tourist eSIMs

Singtel and M1 both sell tourist eSIMs of their own. Singtel says the phone must be carrier-unlocked and eSIM-compatible and that eSIM details cannot be changed after purchase. M1 says a deleted eSIM profile cannot be restored and that you cannot switch from a Tourist eSIM to a physical SIM card. These are local carrier plans rather than one of the providers we compare, so we do not rank them. Check what each includes on the carriers' pages.

FAQ

Questions about eSIMs for Singapore

What is the best eSIM for Singapore from Australia?

It depends on how long you are away and how much data you use. The picks at the top of this page show the cheapest plan, the most data for the money and the best-network option, each with the rule that chose it. The table ranks every Singapore eSIM plan by cost per GB. To see two providers side by side, try Airalo vs Holafly.

What is the cheapest eSIM for Singapore?

The Cheapest pick at the top of this page is the lowest total price among the plans we list, and the table can be sorted by price or by cost per GB. A low price often means a small amount of data or a short validity, so check both before you buy. See how we pick.

Can I get unlimited data on a Singapore eSIM?

Providers sell unlimited plans for Singapore. Filter the table to Unlimited to compare them by price per day. Unlimited plans can come with fair-use rules, such as slowing down after a set amount of data, and the table prints the rule where the provider states one.

Do I need to register a SIM or eSIM in Singapore?

Singtel's hi! Tourist terms say a SIM registered with a passport gives data-only features and is valid for 30 days, and M1's FAQ says tourist SIMs must be registered on purchase with a passport or work permit (Singtel, M1). Singtel says the 30-day limit for passport registrations comes from IMDA's regulations (Singtel), and IMDA limits prepaid to three SIM cards per subscriber (IMDA). Those rules cover SIMs from Singapore's operators. We have not confirmed whether a travel eSIM bought from an overseas provider needs a registration step, so check the plan page before you buy.

Which network should I choose in Singapore?

Singapore's communications regulator, IMDA, requires each of its four mobile operators to cover more than 99% of the country outdoors on 4G, and its results page does not publish an outdoor coverage percentage for each operator (IMDA). Because it does not rank them, we do not either. Pick on price, data, hotspot rules and 5G, and read the plan page to see which operator it uses.

Can I keep my Australian phone number with an eSIM?

Most phones with eSIM can use two lines at once, so the travel eSIM can handle data while your Australian line stays on for texts. Your Australian line can still start roaming charges, so set it up carefully. Our guide covers the settings: how to keep your Australian number.

Do I turn off data roaming when using an eSIM?

Turn data roaming on for the travel eSIM, because most travel eSIMs are roaming eSIMs, and turn it off for your Australian line so it cannot use data abroad. The steps are in how to set up a travel eSIM.

Will a Singapore eSIM work if I cross into Malaysia?

Every plan in our Singapore table covers Singapore only, so check the plan page before you cross the causeway. If you are spending time in both countries, compare the Malaysia eSIM table as well.

What is the disadvantage of an eSIM?

A travel eSIM needs a phone that supports eSIM and is unlocked (how to check). You need an internet connection to download it, so install it at home over Wi-Fi, and many eSIMs cannot be reinstalled once removed. Every plan in our Singapore table is data only, with no Singapore phone number for calls.

How we compare Singapore eSIMs

  1. We take each plan's price from the provider's site and convert it to Australian dollars on the check date.
  2. Cost per GB is price divided by data. Unlimited plans are compared by price per day.
  3. Network is the Singaporean carrier the eSIM connects to. Hotspot and 5G are as the provider states them.
  4. Each pick follows the rule printed with it, and each is a different plan. Remaining ties go to the lower total price.
  5. We recheck prices at least every 30 days and show the check date on every plan.

How we make money

eSIM Mate is free to use. No link on the site earns a commission yet. Once a provider approves us, its links will: the provider pays us, never you. That will never change your price or the order of plans, and we list providers whether or not they pay us.
