Every unlimited travel eSIM has a limit. The useful question is not whether a fair use policy exists — it always does — but whether the provider will tell you the number before you pay. We read each provider's own terms and recorded exactly that.
How a daily fair-use allowance works
Already know you want unlimited? Check provider options.
- High-speed allowance. The number to look for. Some providers publish it; some state a policy without one.
- Throttled speed. Past the allowance the plan slows down rather than cutting off, until the reset.
- Reset. Every day, counted from activation or from local midnight depending on the provider.
Check these before you pay
- The allowance is per day, not per tripA daily high-speed allowance resets. Running past it slows you down until the reset rather than cutting you off, which is why these plans are still called unlimited.
- The reset clock may not be midnightWhere a provider counts 24 hours from activation, your reset lands at whatever time you first connected — not at local midnight. On a short trip that difference decides which day you lose.
- The throttled speed is the number that matters1 Mbps carries maps, messaging and email. It does not carry video calls or streaming. A plan with a small allowance and an honest throttle can beat one with a bigger allowance and an unstated one.
- Tethering usually comes out of the same bucketIf hotspot traffic shares the main allowance, a laptop backup or a video call from a tethered device can spend the day's allowance long before you expect.
What each provider publishes
Read the “not published” cells as carefully as the numbers. A provider that will not commit to a threshold in writing can change it without telling you, and you have nothing to hold it to.

- Shares the main allowance rather than a separate cap
- Hotspot traffic counts against the same daily high-speed allowance. No separate tethering cap and no stated device limit.

- Depends on the package. Most start when the eSIM first connects to a supported network in its coverage area; some start at installation. Airalo publishes the policy per package before purchase.

Check provider optionsHow NexKit checked this
Every figure on this page was read from the provider’s own terms, help centre or product page on the date shown, and links back to that page. Each fact also states its reach, so a policy read from one product family is never presented as covering everything a provider sells. Where a provider states a policy but publishes no number in the pages we checked, this page says so and lists what we checked. Source links are citations, not paid links. A separately labelled provider CTA may be an affiliate link; commission never changes the evidence, comparison order or recommendation method.
