About SMPP Protocol.

[daehob42316144]

Hi All.

Sometimes,

when I tried to send LMS by generic SMPP, there are some failed request like that.

Q. 'Error null while sending message'

      I wondering that which case has happened like this error?

      I think address is not problem.

      Because the first log's address is my phone number.

      My phone number is not quarantine and blacklist.

Please let me know about this issue.

Thanks,

Best Regards,

Daeho
