Important info

We’ll be doing some system updates between Sunday 9 August and Monday 10 August to improve the service we provide. We expect these updates to commence at 17:00 on Sunday and complete at 08:30 on Monday.

You’ll still be able to call, text and use your data as usual, but you won’t be able to request a PAC, STAC or Switching Information during this time. Please try again after 08:30 on Monday.

If you’ve recently upgraded to Vodafone as part of our seamless migration journey, you may experience a delay in activation of your SIM.

We apologise for any inconvenience caused, and ask that you try again after 08:30.
