Send Sms - Problem

Hello guys,

I’m developing an C# app to send sms.
I’m using pdu mode and now I can send sms, but my problem is that i need to use Portuguese characters(á,à,ç, and so on…) and I can’t.
And i can’t understand were is the problem, do I need to specify a dictionary or something ? Or is in the pdu conversion ?

Many Thanks

Anyone ?

I’ve figured out, instead of 7bit I’m going to use 16bit.
Anyone knows how to do this conversion ? Teste to Pdu 16bit ?
