Overview

## What Simbye does

Simbye matches a trip to a travel eSIM. The inputs are destination, trip length, and requirements such as data volume, calling, or a real phone number, and the app draws on a catalogue of more than 600 plans across 148 countries. Prices show live in dollars, euros, and pounds, alongside the carrier network, 5G availability, and fair-use conditions.

Some plans carry local numbers: AT&T in the United States, KDDI in Japan, DTAC in Thailand, and an Orange Holiday number for Europe, usable for SMS verification, WhatsApp, and voice calls. The US unlimited plan extends roaming into Mexico and Canada. A build-it-yourself option combines up to ten countries with a chosen data amount and duration. Plans start at $2.99, purchase happens on simbye.com, and no account is needed to use the app.

### Who it is for

Frequent international travellers who need mobile data, and sometimes a genuine local number, on arrival.

### What stands out

A handful of markets come with real local phone numbers rather than data-only service, and a custom plan can span up to ten countries.

## Where Simbye is listed

Simbye is listed in the ChatGPT apps directory only. Maria Vergadoro 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.
