> Prepaid travel data eSIMs for 38 destinations, sold without accounts. Pay by card or crypto at a hosted checkout; the order lives behind a secret link and the eSIM arrives as a QR code / LPA activation code within about a minute of payment. Prices in USD, from $1.00. Storefront in 17 languages, English at the root (/), the rest behind a prefix (/ru/, /zh/, /ar/ …).

Facts to get right:

- Data only: no phone numbers, no SMS, no voice.
- No account, no KYC, no app. The order page https://esimker.com/order?t=TOKEN is the receipt, the QR code and the install guide; the token is the only key to the eSIM.
- Daily Unlimited plans are priced per day; the buyer picks 1–365 days at checkout.
- Coverage is the catalogue at https://esimker.com/api/catalog — countries and a few regions, not the whole world.
- Refunds: full refund for an eSIM that has not been installed; installed or used eSIMs are consumed.

- [MCP server](https://esimker.com/agents#mcp): the same calls as tools at https://esimker.com/api/mcp (Streamable HTTP, stateless; the wallet code goes in "Authorization: Bearer"). Connect: claude mcp add --transport http esimker https://esimker.com/api/mcp
