How can I know that iMessage is active?

iphone messages

If I see such keyboard (please, take a look on the image below), am I right with that: iMessage is active? enter image description here


The upward pointing arrow in green circle indicates that the message will be send as SMS and not as an iMessage. The name/contact of recipient must be green too.

For iMessage the name/contact would be blue.

  • Contact shown in blue, registered in iMessage:

  • Contact shown in green, not-registered in iMessage, will be sent an SMS:
