SIM registration rules by country
早わかり
This table records only what each country's own authority says about prepaid SIM cards bought in that country. A travel eSIM bought before the trip usually works by roaming, which the destination's registration rules may not cover. A cell marked not verified means we have not found an official statement yet — not that there is no rule.

よくある質問
Does a travel eSIM need registering?+
It depends on the plan and the country. Most eSIMs bought before a trip roam and need no registration with the destination's authority, but some plans that include a local number may ask you to verify your identity. The plan page says so when it applies.
Why do some cells say not verified?+
Because we only fill in what we read on an official page. Where the official page does not address the point clearly, we leave it open rather than guess from blogs or other sellers.
