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.

### Who it is for

Travellers who need mobile data abroad and want to compare plans before buying.

### 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.
