Actress who revealed her number in instagram for voice mail

You're likely thinking of Emma Watson!

In 2019, Emma Watson, the British actress best known for her role as Hermione Granger in the Harry Potter franchise, revealed her personal phone number on Instagram as part of a campaign to raise awareness about the importance of voicemail.

Watson, who is also a UN Women Goodwill Ambassador, used her platform to encourage her followers to record a voicemail message for her, using the hashtag #VoicemailForGood. She then shared her own voicemail number on Instagram, asking fans to leave a message for her.

The campaign aimed to highlight the importance of voicemail as a way to connect with others and to promote empathy and understanding. Watson's move was seen as a bold and innovative way to engage with her fans and to use her platform for good.

It's worth noting that Watson's voicemail number was only available for a limited time, and she later removed it from her Instagram post.
