Thanks @Roisinodonoghue, Three+ doesn't have a specific number and competition winners would be contacted via our Loyalty team who also may be calling about an offer thats available on your account.
As per Three+ competition terms and conditions only one attempt to contact winner(s) will be made by Three and that will be by one phone call only to the contact number provided by entrants at point of competition entry. To be able to win the Prize, the selected entrant must answer their phone when called by Three.
