Knowing what errors you are getting or what "i cant get success" means might help a great deal.

The very first thing you need to check is if your modem supports PUD format? There are commands to do that. I do not remember them now but you can find them easily bu Googling.
If it does, the next step is to configure it to work in PUD mode and then you need some code which converts your data into PUD format. You need to be sure that your input is correct.
