Cambio de proveedor de fibra

Cambiar de un proveedor mayorista de colaboración de fibra de NTT a otro reutilizando normalmente la misma línea de acceso de fibra.

Solicite un número de autorización de cambio de proveedor al proveedor actual y entrégueselo al nuevo proveedor antes de que caduque. El cambio es principalmente contractual, pero las transferencias de opciones, los números de teléfono IP, los enrutadores y la configuración de IPv6 requieren confirmación.

No cancele primero de forma independiente la fibra antigua a menos que se le indique: eso puede convertir un cambio de proveedor en una nueva instalación y generar tiempo de inactividad. Confirme la fecha de cambio, la factura anterior anterior, la nueva tarifa inicial y cualquier servicio que no se mueva automáticamente.
