• search_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 and worldwide plans that include France. For a trip through several countries, filter coverage_type="regional" or "global" to get one eSIM for the whole route; for a single-country trip a "country" plan is usually cheapest. Returned price is the final amount the customer pays at checkout (all fees included), in the requested currency. To buy: call create_checkout_link with the plan id, give the returned URL to the user. They confirm their email with a 6-digit code and pay there; nothing is ordered until they do. After payment they are emailed a link to their eSIM; opening it on their phone gives a one-tap install, the QR code and manual codes. No account needed.

  Parameters:

  • limit — integer — Max results to return
  • region — string — Region name, e.g. "Europe", "Asia"
  • country — string — Destination country as ISO 3166-1 alpha-2 code, e.g. "JP" for Japan. Matches plans of any coverage type that include it.
  • coverage — string — Exact coverage area name for a regional or worldwide plan, e.g. "Europe+", "CENAM", "Global" — get valid names from list_regions
  • currency — string — Currency for prices: "usd", "eur", or "gbp". Defaults to "usd".
  • max_price — number — Maximum total price in the requested currency (checkout total)
  • min_data_gb — number — Minimum data allowance in GB
  • coverage_type — string — Restrict to single-country plans, multi-country regional plans, or worldwide plans
  • duration_days — integer — Exact plan duration in days

• get_esim_plan

  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. They confirm their email with a 6-digit code and pay there; nothing is ordered until they do. After payment they are emailed a link to their eSIM; opening it on their phone gives a one-tap install, the QR code and manual codes. No account needed.

  Parameters:

  • plan_id (required) — string — Plan id returned by search_esim_plans
  • currency — string — Currency for prices: "usd", "eur", or "gbp". Defaults to "usd".

• create_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 to pre-fill the checkout form. The buyer confirms it with a 6-digit code we email them, then pays — nothing is ordered until they do. After payment the buyer is emailed a link to their eSIM within a minute; opening it on their phone gives a one-tap install, the QR code and manual installation codes. No account or signup is required.

  Parameters:

  • plan_id (required) — string — Plan id from search_esim_plans
  • email — string — Buyer email to pre-fill at checkout (they verify it before paying; the eSIM is delivered there)
  • currency — string — Currency for prices: "usd", "eur", or "gbp". Defaults to "usd".

• list_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.

  Parameters:

  • currency — string — Currency for prices: "usd", "eur", or "gbp". Defaults to "usd".

• list_regions

  List every multi-country coverage area Siima sells — regional areas such as "Europe+", "South East Asia" or "CENAM", and worldwide plans — with the countries every plan in it covers, how many plans it has, and its cheapest total price. Use this for a trip crossing several countries: pick a coverage area whose `countries` list contains the whole itinerary, then pass its name as `coverage` to search_esim_plans. `countries_on_some_plans` lists countries only some of the area's plans include — if the itinerary needs one, confirm the chosen plan covers it with get_esim_plan before buying. For a single-country trip use list_destinations instead.

  Parameters:

  • country — string — Only return coverage areas that include this ISO 3166-1 alpha-2 country, e.g. "IT"
  • currency — string — Currency for prices: "usd", "eur", or "gbp". Defaults to "usd".
