   I happen to rarely have a blank microsd card right here.  I can use it.
   i'll want to head indoors briefly, maybe in half an hour.
   let's put this microsd card in.  it's 829
   oh!  I moved it to this phone.
   but there's nothing on it.
   umm it's on the same caddy as my sim card.
   829
   i'll plan to reboot this phone, migrate the microsd card, and try again
   after it boots up.  maybe the airplane mode issue will go away.
