## What it is
A free web-based toolset for existing Giffgaff (UK) and Simyo (NL) subscribers to convert physical SIM cards to eSIMs, transfer eSIMs between devices, and generate activation QR codes. It automates carrier flows via OAuth 2.0 PKCE and GraphQL APIs, processing all data locally in the browser.

## Use cases
- convert my giffgaff physical sim to esim
- transfer esim to a new phone on giffgaff
- generate an esim qr code for simyo
- reactivate giffgaff esim without calling support
- get esim activation code for simyo nl
- move my simyo number to a new device

## When to choose
- you already have a Giffgaff or Simyo number and need eSIM conversion or device transfer
- you want a browser-based, no-install flow that processes data locally
- Simyo's official app cannot generate QR codes and you need one

## When to avoid
- you are a new customer trying to get a number for the first time
- you cannot risk violating carrier terms of service with an unofficial tool
- you use a carrier other than Giffgaff or Simyo
