My total take on ALL phones:
Deb's phone had speaker/mic problems therefore was NOT WORKING/broken.
Jeremys personal phone was fine.
BOTH of the above were on (partial?) restricted access as of Monday afternoon. (Possibly before that and was placed on full restriction at that time)
Jeremys work phone was fine all around.
Sunday when Deb was at the birthday party, her father gave her a plain jane, but UNBROKEN phone from her grandfather that he no longer used...and did NOT have service.
Sunday evening, possibly Monday morning, Deb was transferring #'s from her phone to her grandfathers that still had NO service.
When my daughter was late on her phone payment (different provider and in Canada mind you) when she phone to have some of her features removed...they wouldn't do it until her account was up to date, so I find it hard to believe that Deb could transfer service to her grandfathers phone when they were delinquent with their payments.
Mostly my opinion only
