The Netzing NE110 (as well as other MTK phones) seem to have a bug in
their MO-SMS code. Dieter has told me he is looking at a workaround to this
(by sending dummy authentication request/response), and he will e-mail this
list once he has some results.
This was a tough one. I tried Authentication and Ciphering commands in
various combinations without any success. Finally I changed the allocated
channel to SDCCH instead of TCH. And voila, it worked, even without
Authentication and/or Ciphering.
So it seems that there is a problem with MTK phones (and maybe others)
and MO-SMS on a TCH channel. I am not sure yet if there is a workaround
to solve this and still use the TCH.
Best regards,
Dieter
