I am getting GENERIC_NACK response while trying to Submit request with SubmitMulti() function.

Client.Submit(SMS.ForSubmitMulti()
.ServiceType("test")
.Text("Test Test Test Test Test Test Test Test Test Test")
.From("MyService")
.ToDestinations(destList)
.DeliveryReceipt()
);

Kindly suggest what should be resolution for this issue. And kindly suugest what are the parameters which are mandatory for submitting multisubmit,

Any update ?

Could you please post here trace log file from your application?
I would check what data library transfers to SMSC and what data is received from SMSC.
