I have this SMS Submit PDU : 00 51 00 0B 91 06 61 14 51 51 F5 00 F5 A7 8C
NO matter how I count, I still think that it is 15 octets.
When I send an operator logo, I append a logo message or 140 octets
(Nokia Op Logo sample) to the PDU.
And I do this
<paste the pdu + logo message><CTRL+Z>
It gives me error. But, If I set the length to 154 it works.
Why? How come the octets of the PDU is actually one less??
