Probably I have missed something or the way I do testing is not correct. I hope somebody can assist me on this matter.

Same here McGuard i hate this same error, i hope someone could help us.

Thank you in advance,

It's been so many years since I created code for this so I don't remember enough to help you with details. These days however there are so many libraries and applications that do the same thing so take advantage of them instead of struggling yourself.

Even if you decide to struggle on cross-referencing with the PDU output of another application will be very useful. Here's one google hit http://twit88.com/home/opensource/sms
