The shell company isn't a strict requirement, and I'd wager less likely. Infiltrating the delivery process would be easier and would instead require knowing about the pager purchase and being able to swap the actual package for an alternative package. Theoretically all of this is possible with some data interception to discover the pager order, a team to construct the exploding pagers, a person to deliver the exploding pagers, and a person to intercept the actual pagers (which could be the same person delivering the exploding pagers).
