Who it is for
Travellers who need mobile data abroad and want to compare plans before buying.
eSIM Finder
Compares prepaid travel eSIM plans inside chat
Overview
What eSIM Finder does
eSIM Finder looks up prepaid mobile data plans for travellers heading to any of more than 190 countries and regions. A destination and a trip length are enough to start: the app pulls current plans, sets data allowances against prices in 40 currencies, explains how the plan types differ, and returns a link to whichever option gets picked.
For people who travel repeatedly there is also an Annual Travel Pass, a single data-only eSIM valid for twelve months across roughly 130 countries.
The connector reads data and nothing more. It works anonymously, with no account or sign-up, and has no access to names, email addresses, or chat history. Payment happens on the provider's own store, since the app itself takes no money.
What stands out
It runs the comparison anonymously and hands off to the provider's store rather than processing any payment.

Where eSIM Finder is listed
eSIM Finder is listed in the ChatGPT apps directory only. Frantisek Valent, s.r.o. has no connector under the same domain in the Claude directory; 392 of the 3,150 products here are on both marketplaces, and this is not one of them.
ChatGPT apps are built on MCP, and the same server can back a Claude connector, so the absence is a distribution decision rather than a technical one.
