Hi there @Texasaggiee!
Fantastic questions! I’m happy to help out with the details of our BOGO offers!
It does need to be an entirely new line to be eligible for the BGGO offer. Additionally, if you cancel the phone line you will not receive any further billing credits for it, and the remaining cost of the phone will be billed in full on your next bill!
Thanks for reaching out about this! It’s always good to investigate a bit before making a big commitment. Let us know if you have any other questions, alternatively you can check out our main BOGO page!
