Interesting. I just called VZW and tried to re-activate the old line with a new MTN but they couldn't do it. At first they said sure, but then the rep realized she couldn't. Either I port back the original number, or the line must cancel. I asked if they could process the cancellation today rather than wait to the end of the billing cycle, and again the rep said sure, but then had to backtrack the statement. Since there is already a cancellation order in she can't submit a new one (and she can't cancel the other order, either.)
