Hi
I am today sending SIM OTA messages over SMPP using Submit_SM but to get better control i would like to use Forwarding mode and that is only supported when using Data_SM. The problem is that there is no Protocol_id parameter in a Data_SM, i have to specify "SIM Data download" to address the simcard.
So is there another way to provide that information or is it not possible to use Data_SM for SIM OTA?
