Most travel eSIMs allow tethering. That is not the useful question. The useful questions are how much tethering you get, whether it comes out of the same allowance as your phone, and whether the hotspot needs setting up by hand before it will work at all.
Already know you need to tether? Check provider options.
Planning a Japan trip? Compare Japan eSIM options using the same network, data, validity and hotspot questions before you choose.
“Hotspot supported” on a comparison table can mean unlimited sharing on the main allowance, or a small separate daily cap. Those are very different products.

Check provider optionsEvery 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.
