I'm using an LG 575 handset as a GSM modem. This is the relevant
section of my /etc/kannel/kannel.conf:
group = smsc
smsc = at
modemtype = LG575
device = /dev/rfcomm0
speed = 115200
log-level = 0
sms-center = "+14047259000"
keepalive = 1
sim-buffering = true
group = modems
id = LG575
name = LG575
When I start up kannel and then send an SMS message to this handset,
kannel detects and reads the messages, then tries to delete them, but
the messages don't disappear.
Here's a section of my bearerbox log that shows the problem:

Notice how 3 messages are detected, then I read each one, then each are
deleted, but at the very end, they are still there at the next check?
All advice is welcome.
I really wish I didn't have to use sim-buffering, but this handset doesn't seem
to indicate that an SMS message arrives.
Maybe I need a different CNMI string. I have tried AT+CNMI=1,2 and
AT+CNMI=2,1 and neither cause my modem to send notifications.
