Please contact your mobile network provider. They need to enable your phone number via their network so that imessage sending works with your phone number. This is usually activated internally when you enable imessage, but at times require operator assistance since it invokes mobile network and account aspects.


Alternatively, you can also send imessage using your apple email id by going to


Settings—>Apps—>Messages->imessage(on)

>Send & Receive


Under “Start New Conversations”

✔️ Phone number

✔️Apple email id


Please note when sending using apple email id, the recipient will get messages sent from showing your apple email instead of phone no:
