If you're talking about Message+ and Integrated Messaging, then yes. If all the devices are logged into Message+ using the same profile they should all receive the same text messages to that number.
As jav6 mentioned, this answer will really depend on what you mean by "this feature". If you are asking about the Integrated Messaging service that's available within Verizon Messages, any device signed in would receive messages sent to the designated cell phone number. Any device that isn't signed in at the time the message was sent would not receive the message. We hope this helps. Let us know if you have any other questions.
