What you would have to do is add a second line. They would activate the Bionic on that second line. Then they could transfer the bionic over to your primary line and add a dummy phone to your second line and make the dummy phone have no data, texts, or any usage at all really so in the end you will end up paying an extra 9.99 per month onto your bill for two years.
In essence if you think of it this way, you are kind of paying full retail price for the phone with half upfront and the other half over two years.
You do not have to actually have a phone to put on the dummy line, they can put a fake one on there. What is cool is you'd have an extra phone number/line in case a family member needed it or something or if you give your primary number out to someone like say someone you meet say at a bar then regret it later, you can switch to the other line/phone number and be good to go again haha
