For a short trip, Airalo is the cheapest unlimited plan in the table: $9.50 for 3 days and $15 for 5 days, and it only showed its 7-day plan in euro on the day we looked. Ringo Light no longer sells 3 or 7 days. Its shortest trip is 2 weeks at $18.99, one payment, against $27.50 at Holafly and $28.99 at Saily for a single week.
For a month, Ringo Light and Nomad tie: $32.99 with us, $33 at Nomad. Airalo and Ubigi follow at $49, Saily and Holafly at $71.99 and $73.90. The difference is how much runs at full speed. Our 30 days starts with 20 GB, and when you have used 80% we add 10 GB once and charge the $18.99 top-up, so a heavy month with us costs $51.98. Nomad gives 2 GB a day at full speed for its $33. If you will use more than 20 GB, buy Nomad; we would rather you read that here than at checkout.
Read what unlimited means before you pick. Saily gives 5 GB a day at full speed, then 1 Mbps. Nomad gives 2 GB a day. Airalo states a daily allowance on its listings. Ubigi gives 60 GB across the month, then 2 Mbps. Holafly states no daily cap for your own phone and limits sharing to 1 GB a day. Ringo Light has no speed cap: the 2 weeks starts with 10 GB and the 30 days with 20 GB, each adding 10 GB once at 80%, charged.
Nomad, $10 for 10 GB. Cheapest 10 GB for 30 days, and 50 GB for 10 days at $12 is the cheapest big bucket anywhere in the table. On True, AIS and dtac.
Saily, $10.99 for 10 GB. 20 GB for $19.99, the cleanest app of the six, on AIS and True. 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, $10 for 10 GB but only 7 days. For 30 days, buy its 20 GB at $18. Small buckets from $4 for 1 GB, on AIS and True with 5G.
Ringo Light, no buckets. Our 2 weeks starts with 10 GB for $18.99, nearly double what Nomad charges for 10 GB over 30 days. For a bucket, buy Nomad, Saily or Ubigi. Buy ours for unlimited, not as a bucket.
Ringo Light is our own data eSIM, sold to fund the full Ringo, one plan that works everywhere with your own number ported onto it. For Thailand it sells two trips, both unlimited data at full speed with no speed cap: 2 weeks at $18.99, starting with 10 GB, and 30 days at $32.99, starting with 20 GB. Each adds 10 GB once at 80%, charged at $18.99. One payment, nothing renews. The eSIM arrives by email in seconds and installs in one scan, no app.
A plan over $10 makes you a Ringo Pioneer with €5 off the full Ringo at launch. The card to buy it is just below this article.
A long weekend in Bangkok. Airalo unlimited, 3 days, $9.50. Ringo Light no longer sells 3 days.
A week or two on the islands, phone only, no counting. Airalo unlimited, 5 days, $15, if five days is enough. For longer, Ringo Light unlimited, 2 weeks, $18.99, less than Holafly at $27.50 or Saily at $28.99 for one week.
Two weeks, light use, budget first. Nomad 10 GB at $10, or Saily 10 GB at $10.99.
A month in Chiang Mai, laptop on the hotspot. Nomad unlimited at $33, since its 2 GB a day adds up to more full speed data than our 20 GB start. Ringo Light 30 days at $32.99 if you will stay under 20 GB and want no app.
You need your own number to keep ringing. None of these travel plans does that. The full Ringo, which Ringo Light funds, ports the number you have.
For a short trip of unlimited data, Airalo: $9.50 for 3 days and $15 for 5 days on 26 September 2026. For a month of unlimited, Ringo Light at $32.99 and Nomad at $33. For 2 weeks, Ringo Light at $18.99, against $27.50 at Holafly and $28.99 at Saily for one week. For a 10 GB bucket, Nomad at $10 for 30 days.
Airalo, Saily and Ubigi ride AIS and True. Holafly rides True and dtac. Nomad lists True, AIS and dtac. All six sell 4G and 5G where the network offers it.
Every brand has a limit somewhere. Saily slows you after 5 GB a day, Nomad after 2 GB, Ubigi after 60 GB in the month. Holafly states no daily cap for your own phone. Ringo Light has no speed cap: it starts with 10 or 20 GB and adds 10 GB once at 80%, charged.
AIS, True and dtac all sell tourist SIMs at Suvarnabhumi and Don Mueang, often 8 to 15 days of unlimited for about $10 to $20. An eSIM saves the queue and lets you land connected; for a short trip the prices are now close.
