the issue is not the SMS representation during transport but the representation for the recipient. Our business is M2M communication and we see older systems that require text mode SMS. As our gateway is not meant to support a variety of use-cases disabling
PDU mode SMS in general is not really an option.</div>

I expect we will just send the SMS by AT commands directly in this case.</div>

I don't see it as a property of the SMS message, because if I<br>
understand it correctly, the message will anyway be encoded as a PDU<br>
by the time it hits the radio network (so the text to PDU conversion<br>
is done by the modem itself, not by ModemManager). That's why I<br>
suggested a udev tag, because this is a manual workaround to apply on<br>
specific setups. Maybe your issue is not related to the mode used when<br>
sending the SMS with AT commands, and is more related to how the SMS<br>
PDU is being built by MM (e.g. encoding used and such).<br>
