My phone's SMS memory is currently full. I know that there are waiting
SMSs for me on my SMSC, but I would like to backup some im****tant SMSs
before I free up some memory. I use T-Mobile USA.
My questions are:
1) how long is an SMS queued (and retried) on the SMSC before it is
deleted?
2) if it is eventually deleted having gone undelivered, is it billed?
thanks,
B
