"Alternate Number" appears twice in the signup process
Once on the first page where most people will take it as their home (or spouse's) number
Once on the second page inside the "box" for porting one's number from their old carrier.
This second usage is confusing .. is this the alternate number registered with the old carrier when that old plan was obtained ?
Is this the same home phone from the firts page ?
Is this the "alternate number" being ported to Public Mobile ?
(the number entered in the "check eligibility" box does NOT look like is is part of the information used to do the porting because it is out side of the box listing the old plan's information.)
So .. basically this part of the signup/registration page needs some more human factors
