Simple - you can opt out any time. Just:
- Log in to My Vodafone or
- Text REMOVE IOU to 468 or
- Call us on 2345 and choose option 3, then option 2, then option 4
If you’re already using your Vodafone IOU credit when you opt out, you’ll still be able to use up to your £3 limit. You’ll pay it back when you next top up, plus the 45p charge. After this, you won’t be able to use it again unless you opt back in.
