Contract

Cambio fornitore di fibra

Passaggio da un fornitore di collaborazione in fibra all'ingrosso NTT a un altro riutilizzando normalmente la stessa linea di accesso in fibra.

Richiedi un numero di autorizzazione al cambio fornitore al fornitore attuale e consegnalo al nuovo fornitore prima che scada. Il passaggio è essenzialmente contrattuale, ma il trasferimento delle opzioni, i numeri di telefono IP, i router e le impostazioni IPv6 richiedono una conferma.

Non cancellare prima in modo indipendente la vecchia fibra a meno che non venga richiesto: ciò può trasformare un cambio di provider in una nuova installazione e creare tempi di inattività. Conferma la data di modifica, la vecchia fattura definitiva, la nuova tariffa iniziale e tutti i servizi che non si spostano automaticamente.
