Can I ask you how as someone else at the store level? maybe you're direct and I'm indirect is the issue? If it were done as an alternate upgrade, or swapping the upgrade as the person above suggested, that would remove the unlimited data from the line receiving the phone.

As indirect if I upgrade the other line, and then do ESN changes I'll get charged back on the upgrade months down the road saying the line that upgraded immediately went back to their old equipment and Verizon assumes the new equipment was returned. I've fought it, and even though the upgrade date and contract dates remain extended I get no money.
