I'm not sure how vodafone works, but regular users should not be able to call up the carrier and get anything about a corporate account changed. Period. You should probably have both named callers on the account (whom the users could impersonate I suppose) and some sort of confidential knowledge (like a SSN number on the acct or a verbal password or passphrase). The regular employees should not know this password (duh).
Anyone breaking these rules to modify company equipment should be punished under your company's existing vandalism
rules. You HR department should be able to help out here. This is a personnel issue.
