What's a concession line?
A special plan that can be given to employees and agents of a cellular carrier. In my case, from Verizon.
I won't lie, it has its perks but it also has its disadvantages. I cannot do ESN changes myself, but email a special accounts group that can make changes. I also cannot activate high demand devices (iPhone) until consumer demand calms down. For example, while the iPhone 4 did not sell all that well at launch, I still couldn't activate one for a little over a month after launch. I anticipate the iPhone 5 to be even longer than that (through holiday season). The only thing that benefits from this is my wallet lol..
