Fibre Broadband

What is a Circuit Reference Number (CRN)?

What is my CRN?

A CRN (Circuit Reference Number) is a unique identifier for your Vodafone broadband account. A CRN is provided if you avail of our standalone broadband service which does not include a landline voice service. If you have a Voice and Broadband bundle from Vodafone then you will have a landline number rather than a CRN.

Where can I find it?

Your Vodafone CRN can be located in the following places:

  • On the front page of your Vodafone at Home bill.
  • On your Vodafone broadband completion email.
  • Log into your My Vodafone at Home online account and click on the My Details link.
  • Call us on 1907 to speak with one of our agents, please have your customer number to hand.
  • Visit the Vodafone Contact Hub page and start a live chat with one of our agents.

What can it be used for?

Your Vodafone CRN can be used to:

  • Register for your My Vodafone at Home online self-care account, see
  • Validate your account using our telephone support service on Freephone 1907.

Do I need a new modem with Vodafone Fibre broadband?

Yes, only the Fibre Broadband modem supplied as part of your order will work on the Vodafone Fibre Broadband service. Any older Vodafone modem supplied for a standard broadband service will not work on fibre broadband.

If you are upgrading from standard broadband (with Vodafone or any other provider) to Vodafone Fibre broadband then you will need a new modem.

Will an engineer call to my house to install the modem?

You can choose the option to have the engineer set up your modem as part of your order. He will ensure you are set up and that you are happy that the service is working.

Why do I need a new phone socket for Fibre Broadband?

On the installation day an engineer will fit a new faceplate to your master telephone socket. The faceplate has two sockets, one for your new Vodafone fibre broadband modem and another for phone services (telephone, fax machine, Sky box etc.).

The fibre broadband service will only work on a phone socket that has been fitted with the fibre broadband faceplate. You will not be able to connect to the Internet if you plug your Vodafone Fibre modem in to any socket other than the new master socket.

Can I plug the modem into any phone socket in my house?

No. You must plug your Vodafone Fibre Broadband modem directly into the new master socket set up during the installation of your Fibre Broadband service.

During the installation process an engineer will visit your premises and install a new face plate on your master telephone socket. Only this socket will work correctly with your Fibre Broadband modem.

If you have ordered an optional extension socket (which is set up during the engineer's visit) then you can plug the modem into the new extension socket.

Why don’t I need broadband filters any longer?

As part of the Vodafone Fibre Broadband installation the engineer will fit a new master socket which will have one port for broadband and another one for telephone.

This new socket has a built-in filter so there is no need to attach your old broadband filters to either the new master socket or any other extension socket you may have in your premises.

Can I use a mobile broadband stick as backup?

Yes, the primary connection will always be the Fibre broadband but a Mobile Broadband stick can be used as back up in the event that your Fibre Broadband service stops working.

Simply plug the Mobile Broadband stick into your Fibre Broadband modem's USB port and follow the instructions on your computer screen.

Will my email work if I move to Fibre broadband?

There is no need to do adjust your email settings if you are an existing Vodafone Broadband customer. Your email will continue to work as normal when you upgrade to Vodafone Fibre Broadband.

However, if you are switching to Vodafone from another provider then you will need to change the outgoing mail server (SMTP) of your email client (Outlook, Thunderbird etc.).

The outgoing mail server (SMTP) for a Vodafone internet connection is:

Will I need a new computer to benefit from Fibre broadband?

It is not necessary to upgrade your computer but if it's already slow then it may impact your Fibre broadband experience.

Older machines can sometimes have trouble running newer software and operating systems, giving the impression that the broadband connection is slow. If your computer has picked up something nasty such as a virus or malware then it can slow everything down. Make sure you've got the latest computer protection installed - we'd recommend Vodafone PC Protect.

The latest computers have great processing power and slick operating systems which would benefit from the superfast speeds delivered by Vodafone Fibre Broadband.

I heard Fibre broadband is fast but will it be reliable?

Not only will our Fibre Broadband will be very reliable but it means that multiple users can be connected at the same time so your whole family will have a great experience whether using laptops, tablets or smartphones.

Vodafone Fibre Broadband provides speeds in excess of those offered by traditional broadband technologies. This means that not only will you be able to browse and download files quicker, but all other Internet users in the household will experience faster Internet response times.

Whether they are using tablets, smartphones or laptops, your entire household will be able to use the Internet simultaneously and benefit from super fast Fibre Broadband speeds.

How Fibre Broadband works...

A modern network of fibre optic glass cabling runs from your local telephone exchange, sending data at the speed of light. Unlike standard broadband your speed isn't affected by how long the cabling is. Standard broadband sends electrical signals over copper telephone wires. The longer the copper cable is, the slower the speed.

The fibre optic cables run from your local telephone exchange to the green cabinets you'll have seen on/near your street. Your nearest green cabinet should be a lot closer to you than the exchange.

A short copper cable then runs from your nearest green cabinet into your home. The distance the signal travels along is really short - meaning much faster and more reliable broadband speed.

What times are available for Fibre installation appointments?

Appointments are available from Monday to Friday. You can choose from one of two slots: either 9am - 1.30pm or 12.30pm - 4.30pm. You will receive a reminder text message the day before and the engineer will contact you when they are on their way.

If you want to re-schedule your appointment then please call us on freephone 1907 or click below to use our Virtual Agent – TOBi.

Chat with Tobi

Before the engineer arrives at your home they will carry out some work on your local telephone exchange and green street cabinet.

Your current phone service may be affected for a short time (typically less than 10 minutes), however your Broadband service may be unavailable for up to 2 hours while Fibre Broadband is being installed.

Installation should take approximately 2 hours depending on what is required. The installation could take longer if you need additional wiring to move your modem into a room that is not close by the main socket.

Why can’t I use my alarm or Sky Box with Simply Fibre Broadband?

If you don't need a phone line for making calls then our Simply Fibre Broadband product offers the ability for you to get just broadband at a great rate. With Simply Fibre Broadband the voice service is not switched on. It is the voice service that supports things like monitored alarms and Sky Box.

If you wish to use these type of services you can avail of one of our great Home Phone and Fibre Broadband bundles, which include a voice service to support your needs.
