Welcome to Vodafone Community
Vodafone can supply the date, time & duration of outgoing calls made from your mobile number up to the last 24 months (if you have only recently registered your account only details from the date of registration will be provided). However they do not have information relating to the specifics of the call i.e whether it was answered or went to voice mail. If that doesn't answer your querry, you may need to request it under FOI: https://www.vodafone.ie/aboutus/privacy/#accessinfo.
When sending a PM to a mod, make sure to include the following or else they won't respond to your PM:
Your Mobile number:
Your Date of birth:
A number you'd regularly call from your mobile:
