Buy through a link here and the vendor pays me a small commission. Your price stays the same. How that works.

"Unlimited" on an eSIM page usually means one of three things: a daily full-speed allowance, a fair-use clause, or a bare promise. I picked these five to show all three, and the badges say who each one suits.

The prices are list prices in dollars, checked November 2, 2026. Maya's 7-day plan is $19.99. Airalo's Japan plan is $26.50, Holafly's Japan plan $27.50 and aloSIM's Thailand plan $27. Nomad's 7-day US plan is $23 (plan page).

Where the caps are written down

Airalo gives a number. Full speed, up to 20 Mbps, for the first 3 GB each day, then 1 Mbps, which Airalo describes as enough for messages and maps but not heavy streaming. The day resets 24 hours after you start using the package. Over 7 days that is 21 GB at full speed at most. Nomad gives 2 GB a day, which is 14 GB over the same week. aloSIM's Thailand page gives 3 GB a day.

Holafly gives no number. Its FAQ says an operator Fair Usage Policy may slow speeds for no more than one day. Maya says "no caps, no throttling" on the plan page, and its acceptable use policy allows deprioritisation during congestion for usage inconsistent with normal individual mobile use. aloSIM's Thailand page puts its number in a fair usage policy box: 3 GB of high-speed data a day, then 1 Mbps until the next day.

Hotspot

Hotspot is the other rule to check. Holafly shares 1 GB per day, so a 7-day plan shares 7 GB. Maya lists hotspot as included and gives no daily amount on the pages I read. Nomad's FAQ says tethering is supported and states no amount. aloSIM's Thailand page lists hotspot and tethering as allowed. Airalo's Japan page, as I read it, doesn't say. For hotspot detail by plan, see Can you use an eSIM as a hotspot?.

When not to buy unlimited

Pay for unlimited only when the arithmetic works. On Airalo's 3 GB a day, a light week of maps and messages never gets near the cap, and a fixed pack such as the 3 GB plan at $8 would cost less than the unlimited one at $26.50. Unlimited or fixed data walks through the line, and the calculator prices both. Holafly's own lineup is reviewed in the Holafly review.
