Unable to activate iMessage on iPhone with correct phone number and Apple ID

Hi Apple Support,

I am unable to activate iMessage on my iPhone.

My phone number and Apple ID are correct.
Mobile data and Wi-Fi are working.
Date & time are set to automatic.

Please advise how to resolve this issue.

Thank you
