Number Portability

Keep your phone numbers with our simple service

With the Number Portability service, you no longer pay a fee to your old Operator and you keep your phone numbers.

Thanks to our Dual Operator solution, which includes the installation of duplicate equipment at the customer’s premises, your telephone lines can be transferred to Vianova without any interruption to your services.

Vianova has developed a special installation method that ensures your Voice service continues to operate, even during the various stages of transferring the telephone lines from your old Operator to Vianova.
This method involves duplicating the necessary resources (equipment, ports, etc.), thus avoiding the need for a technician to be present on the day when the lines are transferred from the old Operator.

Do you need a new phone number or do you want to change your current one?
Call our Customer Service team to select the new Vianova number of your choice with your local area code.
