signing up for straighttalk and did not register but activated phone

[AC Question]

Hi This evening i purchased a straightalk package with a sim card. I am bringing my own phone & keeping my phone number. I went onto straighttalk .com & not the StraightalkBYOP.com. In the process I didnt register my phone before activation of my service plan. On the other straighttalk I applied to transfer my service ect. Do I have to register my phone still and if so how do i do that. I went to StraightTalkBYOP.com & I did not see the "Register CDMA" to select.
Thank you for your time and i look forward to your answer.
Sunny
