DoCoMo short-mail is not SMS
would not call a suicide bomber Patriot missile

- a short-mail is "attempted once and forgot forever"
  no matter success or failure, will never retry

- the short-mail server doesn't have access to HLR to check
  the handset info or receive alerts from HLR when a mobile
  becomes available in the network.

* in short-mail, the center rings your number once and will
  never call again if can't get through.

* an SMSC will dial again and again, following a pre-defined
  schedule by the operator and depending on what kind of error
  it gets from the network.

  when you turn on the phone coming out of a cinema, the network
  will tell the SMSC to send the messages to you which failed
  when you watching the movie.

  in J-Phone, all these will be tried over 72 hours until you get
  the messages, very reliable service.

cheers,

Ken

Actually, the user interface varies by handset; my F503i has
separate buttons to send as e-mail or short message service.
