The short answer
You hold a Telstra plan and a flight to Changi, and the question is whether to pay the Day Pass or buy a travel eSIM first. I read Telstra's roaming page on 10 November 2026 and set it against the travel eSIMs I priced on 31 October 2026 and against Ringo Light. For one day I would take the Day Pass. For a stopover of three days or more I would buy Ringo Light and keep my Telstra SIM in for calls and texts.
Unlimited data at full speed for 2 weeks at $17.99 or 30 days at $29.99, nothing renews. Airalo asks $48 for 15 days and $69 for the month.
10 GB for 30 days at $13 on StarHub and Simba, and 20 GB at full speed for 7 days at $19, then 2 Mbps.
20 GB for 30 days at $21 and 10 GB at $14, on StarHub and Singtel.
3 days of unlimited at $11.50 on Singtel, with 3 GB a day at full speed, then 1 Mbps.
The Day Pass runs on your own plan at A$10 a day in Singapore, with 2 GB of data a day and unlimited standard calls and SMS, all on one bill.
Prices read on 31 October 2026: Airalo, Holafly, Saily, Nomad, Ubigi, Ringo Light, Telstra, European Central Bank on their own sites or listings, Ringo Light from its catalogue. All in US dollars unless stated. Treat every number as a snapshot.

The prices, charted
US dollars, 31 October 2026. The rivals sell 15 days, Ringo Light 2 weeks. Ubigi's 15 days is 30 GB at full speed, then 2 Mbps. Nomad sells no 14 or 15-day unlimited.
The 30-day plan at each brand. Ringo Light is unlimited data at full speed. Ubigi's month is 60 GB at full speed, then 2 Mbps. Nomad stops at 10 days.
Holafly sells no buckets. Ringo Light sells no bucket either: its 2 weeks is unlimited and lasts 2 weeks, not 30 days.

Want to keep your own number abroad?
That is the full Ringo service: one plan that works everywhere, with your own number included.
It is a separate product from Ringo Light and it is still being built, so it is not on sale yet. Join the waitlist to hear when it opens.
What to see in Singapore, and what your Australian phone needs for it
Eight places most trips from Australia include, from Marina Bay to Sentosa and Changi. Whichever plan you pick, the tip under each one is where your phone matters.
Roam with Telstra, or buy an eSIM
Telstra's International Day Pass lists Singapore in Zone 2 at A$10 a day, about $7, with 2 GB of data and unlimited standard calls and SMS for each day. The day starts when the service is switched on and used abroad, and on most plans it ends at 11.59pm Australian Eastern time. Unused data expires at the end of the day. I read all of this on 10 November 2026 and changed it into dollars at the ECB reference rate of that day, A$1 = $0.69.
That makes 3 days A$30 (about $21), 7 days A$70 (about $48), 2 weeks A$140 (about $97) and 30 days A$300 (about $207), if the phone is used on every day. Telstra's page shows no weekly or monthly pass for Singapore. Ringo Light is one payment: $8.99 for 3 days, $17.99 for 2 weeks and $29.99 for 30 days, so even a three-day stopover is $8.99 against about $21 of Day Pass.
Among the travel eSIMs, Ringo Light is the cheapest unlimited at every length I priced. For 3 days Airalo asks $11.50 and Holafly $11.90. For two weeks Ubigi asks $35 for a fixed amount, Airalo $48 for 15 days, Saily $48.99 and Holafly $51.50, and for a month the rivals run $49 to $76.50.
What Telstra wins is real. One day on a layover is A$10, about $7, which is less than any three-day plan but close to Ringo Light's $8.99 for a whole trip. Your Australian number keeps ringing, calls and texts come with it, nothing needs installing, and a phone with no eSIM slot works. If the 2 GB runs out, Telstra offers a 2 GB top-up at A$10 for 31 days. Its page names no hotspot rule and no roaming speed. Prepaid customers are sent by the page to separate Pre-Paid roaming packs that I did not price, and Optus I left out, because I did not read its page.
Networks in Singapore, and what changes for a visitor from Australia
Singapore has four mobile networks: Singtel, StarHub, M1 and Simba. The island is small and dense, and all four cover the city, the MRT underground and Changi well. Airalo and Holafly ride Singtel, Nomad StarHub and Singtel, and Ubigi StarHub and Simba. Ringo Light uses a local partner network. Telstra's page does not name the network its Day Pass uses in Singapore.
Many Australians cross the Causeway to Johor Bahru or fly on to Bali or Kuala Lumpur. A Singapore plan, Ringo Light included, stops at the border, and Telstra lists countries by zone, so I would read the zone for each stop. If the trip continues into Malaysia, I would look at a regional plan from Airalo, Nomad or Ubigi.
The Day Pass carries calls, so Australian calls and texts reach you at A$10 a day. The travel eSIMs here are data only, with no Singapore number. Calls go over apps that use data, and your Telstra SIM stays in the phone if you want your number reachable.
If you want a data bucket: Ubigi or Nomad
- Ubigi, $13 for 10 GB. The cheapest 10 GB for 30 days, on StarHub and Simba with 5G. Its 20 GB is $16 a month, but that plan renews; the one-off 25 GB for 30 days is $22.
- Nomad, $14 for 10 GB. The cheapest 20 GB that does not renew, at $21 for 30 days, on StarHub and Singtel.
- Saily, $15.99 for 10 GB. 20 GB at $22.99. Its listing is dated 4 October; saily.com refused the fetch.
- Airalo, $16 for 10 GB. Its Connect Lah plan on Singtel, 20 GB for $23, with smaller buckets too.
- ✓Ringo Light, no buckets. The 2 weeks is unlimited for $17.99 and the 30 days unlimited for $29.99. For 10 GB that lasts a month, Ubigi at $13 and Nomad at $14 are cheaper, and for 20 GB Ubigi, Nomad, Saily and Airalo all cost less than the Ringo Light 30 days. I would buy Ringo Light for unlimited, not for a bucket, and I would rather you read that here than at checkout.
What Ringo Light is
Ringo Light is Ringo's own data eSIM, and I write for Ringo, so weigh that. It is sold to fund the full Ringo, one plan that works everywhere with your own number ported onto it. For Singapore it sells three trips: 3 days at $8.99, 2 weeks at $17.99 and 30 days at $29.99, all unlimited data at full speed. It is data only, with no number, no calls and no texts, and it sits beside your own SIM. The eSIM arrives by email in seconds with a QR code and installs in one scan, no app. One payment, nothing renews.
The card to buy it is further up this page, just after the side-by-side table.

We priced Airalo, Holafly, Saily, Nomad, Ubigi and Ringo Light for Singapore on 31 October 2026, all on the same day, in US dollars.

We compare the trips people actually book: a week, two weeks and a month of unlimited data, and a 10 GB bucket. We read each brand's fair use and speed rules and quote them as the brands state them. We did not run speed tests, so this page makes no speed claims for any brand.
Ringo Light is our own product. We put it in the table on the same terms as everyone else, and where a rival is the better buy the page says so.
Left out: Maya Mobile. We could not read its own prices for this country on the day, so it stays out rather than being guessed.
