Imessage, Not able to log into imessage for send and receive section

On my iphone 5s i have activated Imessages, I then want to log in to my apple id for the send and recieve section so that i can use it on mac. All that is shown on the send and receive menu is where i can be reached and that is my phone number. above that i click Use your Apple Id for Imessage. This blue text goes gray and waits for 20 seconds then says there was an error during activation.

I have tried reseting my network settings.

I have tried waiting 24 hours.

I have been connected to wifi the whole time.

My main goal would be so that i can use my apple id for imessage. I wish to log into my messages app on my macbook and use see all my messages as well as reply to them.
