In-store or online? They are not the same

In Japan the way you apply changes what help you can get later. This is the single most important thing to understand.

Contrato de tienda

  • El personal puede explicar el plan en persona.
  • Los documentos se pueden verificar con el personal.
  • Puedes hacer preguntas sobre la marcha
  • Algunos servicios pueden tener una tarifa de tienda.
  • No todos los planes se pueden manejar completamente en la tienda

Contrato en línea

  • Aplicar mediante un sitio web o una aplicación
  • Subes/escaneas tus propios documentos
  • Usted mismo completa la verificación de identidad (eKYC)
  • Se envía SIM o se activa digitalmente un eSIM
  • El soporte puede ser solo en línea
  • Algunos planes de bajo costo están diseñados únicamente para trámites en línea
Price is not the whole story

A cheaper plan can cost you more time and stress if you cannot get help in a language you understand. Every plan page shows a Support Level — not just a price.
