Sending SMS - configure provider

[=?iso-8859-1?Q?Andr=E9_Campos?=]

Hi,

I'm building an application that send's sms. I'm using
the code example from MSDN page. Everything is alright
but the message is not kept in the SIM after the
receiving.
Can anyone help and tell me how to change this code
example to have PS_MESSAGE_CLASS3 instead of 0

private static extern IntPtr SmsSendMessage(IntPtr
smshHandle, IntPtr psmsaSMSCAddress, IntPtr
psmsaDestinationAddress, IntPtr pstValidityPeriod, byte[]
pbData, IntPtr dwDataSize, byte[] pbProviderSpecificData,
IntPtr dwProviderSpecificDataSize, SMS_DATA_ENCODING
smsdeDataEncoding, IntPtr dwOptions, IntPtr
psmsmidMessageID);

Byte[] ProvData = new Byte[12];

byte[] bMessage = Encoding.Unicode.GetBytes(sMessage);
int nMsgSize = bMessage.Length;

res = SmsSendMessage(hSms, IntPtr.Zero, (IntPtr)pAddr,
IntPtr.Zero, bMessage, (IntPtr)nMsgSize, ProvData,
(IntPtr)ProvData.Length,
SMS_DATA_ENCODING.SMSDE_OPTIMAL, (IntPtr)
SMS_OPTION_DELIVERY_NONE, IntPtr.Zero);

Thanks in advance for your help

Yes I have the same problem, like Andre I am using the
code from MSDN

I also can't set it up so that the received sms would be
stored in the SIM card.

Anyone have a clue?
