I did too many attempts to verify primary account to activate my new phone with my current line. It says max attempts try again later.

user_63yeih Hi there! Thanks for using our Forums and for taking the time out of your day to reach us. We are happy to work together to help you get the device activated. To get started can you send us a DM with your name and service address? 
To send a "direct message" / "private message" message to Xfinity Support:

 • Click the "Direct Message" icon
 • Click the "Start new conversation" (pencil and paper) icon
