The short answer
Six travel eSIMs sell a Singapore plan and get most of the traffic for this search. I priced all six on the same day, for a stopover of a few days, a week in the city, two weeks with a trip up to Malaysia, and a month, and I read the fine print on unlimited. Here is where I would buy each one.
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.
Prices read on 11 November 2026: Airalo, Holafly, Saily, Nomad, Ubigi 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, 11 November 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.

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 do in Singapore, and what your phone needs for it
Eight places most first trips include, from Marina Bay to Sentosa and the airport, with the one thing your data does for you at each. Singapore is small: all eight are on the MRT or a short ride from it, and 4G and 5G cover every one.
If you want unlimited for two weeks or a month: Ringo Light
Many people see Singapore on a stopover, but plenty stay a week or two, and some move here for a month of work. For 15 days of unlimited, Airalo asks $48, Saily $48.99 and Holafly $51.50. For a month, $69, $71.99 and $76.50. Ubigi is cheaper at $35 and $49 for a fixed amount at full speed, and Nomad sells no unlimited past 10 days. Ringo Light charges $17.99 for 2 weeks and $29.99 for 30 days, and nothing renews. That is the gap I would look at first.
Read what unlimited means before you pick. Airalo gives 3 GB a day at full speed, then 1 Mbps. Saily gives 5 GB a day, Nomad 2 GB. Ubigi gives 30 GB for 15 days or 60 GB for the month, then 2 Mbps. Holafly states no daily cap for your own phone and limits sharing to 1 GB a day. Ringo Light is unlimited data at full speed for the whole 2 weeks or 30 days. That is the line I read first.
For a short stopover, Ringo Light sells 3 days of unlimited data at $8.99, and no 7-day plan. Airalo sells 3 days of unlimited at $11.50 and Holafly at $11.90. For a week, I would still buy the Ringo Light 2 weeks at $17.99, which already costs less than any rival's 7 days; Ubigi's week with 20 GB at full speed is $19.
Which network works best in Singapore, and the trip to Malaysia
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. Signal can drop inside thick buildings and on the outlying islands such as Pulau Ubin. Airalo and Holafly ride Singtel, Nomad StarHub and Singtel, and Ubigi StarHub and Simba. For a city trip I would not choose on network.
Many visitors cross the Causeway to Johor Bahru or go on to Malaysia. A Singapore plan, Ringo Light included, stops at the border. If your trip continues into Malaysia, I would look at a regional plan: Airalo, Nomad and Ubigi all sell plans that cover Singapore and Malaysia together.
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 the data eSIM Ringo sells to fund the full Ringo, one plan that works everywhere with your own number ported onto it. I write for Ringo, so weigh that. For Singapore it sells three trips, all unlimited data at full speed: 3 days at $8.99, 2 weeks at $17.99 and 30 days at $29.99. Nothing renews. The eSIM arrives by email in seconds and installs in one scan, no app.
The card to buy it is further up this page, just after the side-by-side table.
