Implementation Schedule

Transfer date TBC

When will my transfer begin?

The start of the network transfer will begin between 09:00 and 14:00 on your chosen date.

How long will it take?

The transfer is typically complete by 18:00 on the selected transfer date, however please be aware due to network portability this can take up to 24hrs. If the transfer is not complete by 18.00 we can escalate this with the previous provider the following day after 08.30am

Will I need to change my sim?

You will need to change your sim as you are changing Network provider (i.e. O2 to Vodafone)

Will my service Calls & 3G Data Service be affected?

SMS and voice services will be slightly disrupted during the transition as we move your service from the Current provider O2 to your new chosen Provider Vodafone.

Where possible we would recommend that you are able to access a Landline or Wi-Fi to minimise Service disruption during the process. Note; this is typically limited to under a couple of hours and Daisy will ensure the service is resumed ASAP.

Regarding data access we advise that you stay logged onto Wi-Fi (where available) on the day of transfer as there will be data service disruption when migrating from the current Service Provider to Daisy – note; this is typically limited to under a couple of hours and Daisy will ensure the service is resumed ASAP.

How will I know that my service has changed across to the new Service Provider?

As outlined above, You will receive a new Sim Card for your New Service provider, when the service Ports to the Vodafone platform you will lose service on your current O2 sim, this is an indicator to insert your new Vodafone sim.

Daisy actively monitor progress throughout transfer date(s) and can advise assigned Places Leisure service contacts as required.  For data users, a clear indication of a completed Port is access to 3G/4G services at the end of the transfer date.

If you lose your service please ensure that you Reboot/Power cycle your device and test before reporting an issue as this should refresh your voice & Data on the network.

If your handset is locked to O2

If your handset is locked to O2 the handset will ask you for a NUC (Network Unlock Code). Once you enter your new Vodafone sim card you will be prompted to enter the NUC code. This will unlock your device and enable it to work with the Vodafone sim card.

I am using my own handset

If you are using your own handset we need to ensure that this is able to be used with a Vodafone sim card, the best way to check this is by testing a Vodafone sim card in the handset before the transfer date.

Once you have entered the Vodafone sim, If the handset shows that an unlock code needs to be provided you will need to obtain this from the supplier that it was purchased from before the day of the transfer.

If you are unsure of your handset IMEI please dial *#06# and this will display the IMEI on your screen.

Please contact Phil Lawton or Sue Hayes as they have the unlock codes for your original O2 handset.


Voicemail is generally the last service to transfer, although not a common occurrence you may need to re-record your greeting. Please ensure that you keep a note of your PIN as this may be requested when accessing your voicemail after the migration


Please ensure that any contacts that are saved to your O2 sim card are saved to your phone. Once your new sim is entered you can save to the sim card or keep on phone memory. This only needs to be done with older devices as most contacts are saved through your google account or saved to your apple device through I tunes.
