What can I use the Extra Credit for?
The important thing is that you use your Extra Credit before the regular credit. Whenever you have some free units, for example from one of the Prepaid Bundles , they are used first.
Extra Credit can be used for all regular Vodafone services.
It cannot be used to pay for third-party services (such as SMS tickets) and SMS e-mail.
