Search Siima travel eSIM plans

Search prepaid travel eSIM data plans by destination country (ISO 3166-1 alpha-2, e.g. "JP"), region (e.g. "Europe"), minimum data in GB, maximum total price, or plan duration in days. Plans come in three coverage types: "country" (one country), "regional" (a named multi-country area such as "Europe+" or "South East Asia"), and "global" (worldwide). A country filter matches every plan that covers it, of any coverage type — so searching country="FR" returns France-only plans alongside the Europe

Get eSIM plan details

Fetch full details of a single Siima eSIM plan by its id (from search_esim_plans). To buy: call create_checkout_link with the plan id, give the returned URL to the user. After payment the eSIM (QR code + activation link + manual codes) is emailed to them automatically — no account needed.

Create eSIM checkout link

Create a secure payment link on siima.online for a Siima eSIM plan (Stripe-powered, but hosted on our own site — never a redirect to checkout.stripe.com). Give the returned url to the user to complete payment. Optionally pass the buyer's email so the link goes straight to the payment page; otherwise the page collects it first. After payment, the eSIM QR code, one-tap activation link, and manual installation codes are emailed to the buyer within a minute. No account or signup is required.

List covered destinations

List all countries Siima sells a single-country eSIM plan for, with plan counts and the cheapest total price per country. Country codes are ISO 3166-1 alpha-2. Counts and prices cover country plans only, so they stay comparable — many more countries are reachable via multi-country plans; call list_regions for those.

List regional & worldwide coverage areas

List every multi-country coverage area Siima sells — regional areas such as "Europe+", "South East Asia" or "CENAM", and worldwide plans — with the countries each one covers, how many plans it has, and its cheapest total price. Use this for a trip crossing several countries: pick a coverage area whose country list contains the whole itinerary, then pass its name as `coverage` to search_esim_plans. For a single-country trip use list_destinations instead.
