Hi,
depends :) basically a change of PID and/or DCS should help, refer to TS
03.40 specification, however this will require some testing and/or
device/gateway to send the sms with.
What do you intend to use silent sms for?
Cheers,
Lukas

Do you mean using osmocom or not?
If not the answer is a bit OT, but you can do it easily using AT commands
that almost every phone support.
Have a look at the command AT+CSMP.

Hei,
consider also, that some operators detects silent sms and restores automatically TP-PID
and TP-DCS.
Moreover changing TP-PID/TP-DCS I suggest you to use also Message Waiting
Indication-Discard option [1].
Some examples:
#pdu='0011000C91'+str(num)+'0000AA0141' # SMS Classic
#pdu='0011000C91'+str(num)+'4000AA0141' # 0x40 (TP-PID)
#pdu='0011000C91'+str(num)+'40C0AA0141' # 0x40(TP-PID) and 0xC0(Message
Waiting Indication-Discard)
Cheers,
Luca
