The short answer
You are from Australia, you have Telstra, and you are going to Thailand for a week, a fortnight or a month. I put the Day Pass at A$10 a day, read on 31 October 2026, against the five eSIM brands and Ringo Light priced on 25 October 2026. For a month I would buy Ringo Light at $32.99. For a week I would buy Ringo Light's 7 days at $6.99, and for a day or three I would look at Airalo or the Day Pass.
Unlimited data at full speed for 7 days at $6.99, 30 days at $32.99 or 2 weeks at $22.99, nothing renews. Telstra's Day Pass is A$300 (about $211) for the same month. Airalo and Ubigi ask $49 for a month; Holafly and Saily ask $27.50 and $20.99 for one week.
For light use: 10 GB for 30 days at $10 and 50 GB for 10 days at $15, on True, AIS and dtac. Its unlimited stops at 10 days, at $15.
1 GB from $4, 5 GB from $7, 20 GB for 30 days at $18 on AIS and True with 5G. Unlimited from $9.50 for 3 days and $21 for a week, a cent over $20.99 at Saily.
You buy days, not gigabytes, with no daily cap stated for your own phone, on True and dtac. $27.50 for a week; sharing limited to 1 GB a day.
Prices read on 25 October 2026: Airalo, Holafly, Saily, Nomad, Ubigi, Telstra, Ringo Light, 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, 25 October 2026.
The 30-day unlimited plan at each brand. Nomad sells unlimited only up to 10 days. Ubigi states its month as 60 GB at full speed, then 2 Mbps. Ringo Light is unlimited data at full speed.
The bucket most people buy for a two-week holiday. 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 see in Thailand, and what your phone needs for it
Eight places most trips to Thailand include, from the Grand Palace in Bangkok to the islands of the Gulf. Each one shows what a phone does for you there, and one eSIM works at every stop.
Roam with Telstra, or buy an eSIM
Telstra's roaming page, read on 31 October 2026, lists Thailand at A$10 a day on the International Day Pass. A day is charged when the phone makes a call, sends a text or uses data. Two weeks of use is A$140 (about $98) and 30 days is A$300 (about $211), because the page shows no monthly pass for Thailand. The dollar figures come from the ECB reference rate of 30 October 2026, A$1 = $0.70.
The Telstra Day Pass costs A$140 (about $98) for two weeks in Thailand against $22.99 for Ringo Light, and A$300 (about $211) for a month against $32.99. For a week, Saily asks $20.99 and Airalo $21, against $6.99 for Ringo Light's 7 days. For a month, Saily asks $48.99 and Airalo and Ubigi $49.
Telstra wins on what a price does not show: your own number, calls and texts included, nothing to install, and it works on a phone with no eSIM slot. For a stopover of a day or two I would use it. For three days, Airalo's $9.50 is the price to beat, since Ringo Light sells no 3 days for Thailand.
Networks in Thailand, and what changes for a visitor from Australia
The brands in my table ride the Thai networks True, AIS and dtac. Nomad lists True, AIS and dtac, Saily and Ubigi AIS and True, Airalo AIS and True with 5G, and Holafly True and dtac. I did not read a coverage map for Thailand, so I would not promise the same signal on every island.
The Day Pass runs on your own Telstra plan. It includes 2 GB of data a day and unlimited standard calls and SMS, and unused data expires at the end of each day. Past 2 GB, Telstra sells a data top up of 2 GB at A$10 (about $7), valid for 31 days. Its page states no roaming speed, and I will not fill that gap with a guess.
If you want a data bucket: Nomad, Saily or Airalo
- Nomad, $10 for 10 GB. The cheapest 10 GB for 30 days, and 50 GB for 10 days at $15 is the biggest bucket under $20 in my table. On True, AIS and dtac.
- Saily, $10.99 for 10 GB. 20 GB for $19.99, on AIS and True, with a full refund inside 30 days if you never install it.
- Ubigi, $11 for 10 GB. 25 GB for $24.90 on AIS and True with 5G. The app is needed for top-ups.
- Airalo, $11 for 10 GB for 30 days. 20 GB at $18, with small buckets from $4 for 1 GB, on AIS and True with 5G.
- ✓Ringo Light, no buckets. The Ringo Light 2 weeks is unlimited for $22.99, more than double what Nomad charges for 10 GB over 30 days. Telstra sells no bucket, only 2 GB a day. For a bucket, I would buy Nomad, Saily or Ubigi, and Ringo Light for unlimited.
What Ringo Light is
Ringo Light is the data eSIM I write for, sold to fund the full Ringo, one plan that works everywhere. For Thailand it sells three trips, all unlimited data at full speed: 7 days at $6.99, 2 weeks at $22.99 and 30 days at $32.99. Nothing renews. The eSIM arrives by email in seconds and installs in one scan, no app.
It sits next to your own SIM, so your Australian number keeps working for calls and texts if you leave Telstra roaming on for those. A day with a call or text on it still counts as a Day Pass day at A$10, so I would turn roaming on only when I need it. The longer Telstra page is at /blog/telstra-vs-ringo-for-thailand.
The card to buy it is further up this page, just after the side-by-side table.
Pick by trip
I would stay on the Day Pass for one day, or buy Airalo unlimited for 3 days at $9.50. Ringo Light sells no 3-day plan for Thailand, but its 7 days at $6.99 costs less than Airalo's 3 days.
I would buy Ringo Light's 7 days at $6.99, against Saily at $20.99 or Airalo at $21 for the same week.
I would buy Ringo Light, 2 weeks, $22.99. The Day Pass is A$140 (about $98) for fourteen days.
I would buy Ringo Light, 30 days, $32.99. A month of the Day Pass is A$300 (about $211).
I would buy Nomad 10 GB for 30 days at $10.
Keep your own SIM in the phone for calls and texts and add Ringo Light for data.

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.
