They might be for some old services that were carried over.
Other Operator charges are services that you had in place with your previous provider and are automatically transferred over when you join Vodafone.
These charges include services such as:
- Eircom.net dial-up internet packages
- Call barring
- Equipment rental etc.
They are charged on to you at exactly the same price as Eircom charged before you joined Vodafone.
