Does sim buffering cause messages to be stored on sim before being sent?
If this is the case, you should disable it, so messages are sent using
AT+CMGS straight, instead of using AT+CMGW and then send it.
Just using my logic, as I'm not an expert.
Someone else correct me if I'm wrong hehehe.

Hello Thank you for reply.
I am trying lot of things to get out of this issue. interesting thing
is i don't see this issue reported that much, just feels like i am not
only one.
my current throughput is 5, and tomorrow i am going to set it even
lower, something like 0.1 to see if my USB stick modem is too weak for
sending 1000 or not.
i am using memory storage = SM i tried ME as well, but both causes
the issue. DLR is stored in MySql. i am not sure what you mean by
using same memorey for MT and MO, i found that in Kannel, only drl
storage and message-storage is the two options. is there any other
storage choices?
Sim buffering is set to true, but i tried with false as well i think,
but i am not sure about this. What do you think is the right option
for such USB stick GSM modem?
Modem connectivity is OK, because we have passed that stage already,
our SMS sending, delivery report receving is working cool just when we
try to send above 500 SMS at a single shot then it fails. can you give
me some idea how can i avoid too many stored message problem. because
i am not sure whether i have any option to avoid such thing.
Thank you

Hi hard to say what the problem is but
_) Verify that your modem is not storing messages in its internal
buffer
_) Your modem migh freeze because of too many stored messages
_) If you decrease the throughput thoughput=10, still having the
same problem?
_) Check with minicom or other terminal sw of you can connect to the
modem and verify memory status.
_) Some modems use the same memory allocations for MT & MO... might
you have MO stored in your modem?
_) Set logs to debug to see if you get more info
Hope helps
