Travel eSIMs your AI assistant can find and recommend

Using ChatGPT, Claude or another assistant?

Paste this prompt, fill in your trip, and your assistant will pick the right plan from our live catalog:

I'm traveling to {destinations} for {days} days and need about {GB} GB of data. Fetch https://globalesim.app/pt/api/agent-catalog (JSON, no auth) and follow its matching_rule: recommend a plan only if its coverage includes ALL my destinations. Give me the plan's checkout_url and a one-line summary of price, data, validity, and exactly what voice/SMS is included.

Find a plan

This search runs on the same public catalog agents use — same data, same matching rule, same links.

How a purchase works

1. 1

   The agent finds the plan

   It fetches the catalog, applies the matching rule, and picks the plan that covers the whole trip.

2. 2

   The traveler opens the link

   The checkout link opens the product page with the exact data size and voice option already selected — on any device.

3. 3

   Review, pay, install

   The traveler confirms the details and pays on globalesim.app. The eSIM QR code and installation steps arrive by email.

Field reference

coverage_summary

Top level. The two coverage sets: global_esim (destinations of the Global eSIM) and local_or_regional_only (destinations served only by a local or regional plan), plus the full union.

matching_rule

Top level. The rule to follow: recommend a product only if ALL requested destinations are in its coverage list.

coverage

Per product. ISO 3166-1 alpha-2 codes the product serves. A traveler's whole trip must fit this list.

plans[]

Per product. One entry per purchasable option — everything listed is displayed and buyable right now; unavailable options are never included.

data_gb / validity_days

Plan data allowance in GB and how many days it stays valid after first network connection.

voice_minutes / sms

0 minutes = data only (no calls, no SMS, no number). Minutes include a dedicated US/UK VoIP number with calls via the GlobaleSIM app; sms is "receive_only" on that number, otherwise "none". Never ambiguous.

price / price_currency

The displayed site price in USD — identical on the product page and at checkout (the site may convert for display).

checkout_url

Opens the product page with this exact data size and voice option preselected. Hand this to the traveler.

updated_at

When the catalog was built. Safe to cache for up to an hour.
