Depend how do you set the SMS buffering using CNMI if I remember. Modem
has 1024bytes of memory most of the time that can buffer more then 1 sms.
Modem rise a irq when they receive a call or sms, or you an use the serial but
omap family can loose the first char coming from the serial so you can lost the
sms because parsing fail
