Upgrade Sharing details
If anyone can help, I would greatly appreciate it.
Currently we have a family plan with 2 smartphone lines and 2 non-smartphone lines. I would like to use an upgrade, that is available on one of the non-smartphone lines, for my smartphone line to purchase an iphone 6 plus at the "discounted" price.
I understand the "upgrade sharing" between the two lines, what I don't understand is the details of that transaction. Are the upgrade eligibilities simply exchanged between the two select lines? Or are additional elements of each line exchanged as well?
