Virgin Mobile - programming Kyocera 2255 phone

I was on Sprint for years with the old 300/$30 plan,
but my mins were only about 20 last month.
So - I opted to re-activate my son's old Virgin Mobile 2255 (Super) phone,
and transfer my current sprint cell number.

I called Virgin Mobile today... walked thru IVR hell to get to real person,
and then "Derek" took all my info (including SSN),
and walked me thru the re-programming
of my Qualcomm / Kyocera 2255 phone.

Now the problem....
It seems it can call out, get to voice mail, send SMS msgs,
but it will not receive phone calls,
and only gets SMS in some random time related way.

I think that the phone number data might be used on "outgoing calls",
and the Net ID number data used for "incoming calls".

For some reason,
Derek had me setup the NMSID to some different 708-123-xxxx number
708 is another local overaly area code,
rather than my 630-456-xxxx phone number.

But - when I go back to the NMSID screen entry,
my 630-456-xxxx phone number is there !

I'll call again tomorrow and see if we can figure anything out.
