Tracfone is funny. They are a parasite provider- they don't own a single tower. Thier deal with the FCC might be a little different than a regular carrier's about migrating an old phone number. I know that most cell providers really dislike Tracfone, so they might be dragging thier feet to show that there are advantages to staying with them, just like the advantage of only being able to talk to thier towers.

But I don't see why it should take that long otherwise.
