The above pdu code is sending the sms. but the recieving nuber is gets this sms as two sms’s and some garbage characters are adding the starting of text whre is the mistake please let me know as early as possible. it is very urgent for me

I’ve built an sms gateway, I’m using unicode due to Portuguese language use of punctuation.
Now we are in need of sending bigger sms, 70 char is not enough.

I need to learn how to build multi part pdu.

0041 : Sms-Submit + UDH bit

000B915121551532F40000 : What is this ?

A0 : total payload lenght

05 : user data header lenght

00 : IEI
03 : IEDL
00 : Ref nr
03 : Total
01 : Current Part
: Concatenated message

986F79B90D4AC3E7F53688FC66BFE5A0799A0E0AB7CB741668FC76CFCB637A995E9783C2E4343C3D4F8FD3EE33A8CC4ED359A079990C22BF41E5747DDE7E9341F4721BFE9683D2EE719A9C26D7DD74509D0E6287C56F791954A683C86FF65B5E06B5C36777181466A7E3F5B0AB4A0795DDE936284C06B5D3EE741B642FBBD3E1360B14AFA7E7 : is this the message, dates, smsc,sender, receiver ?

I really need to learn how tu build an multipart pdu.
Any help ?

Here you guys can see how i build my pdu, i need to change it in a way to send multi part.
Its c#

public static string GetPdu(string number, string message, string smscAddress, out int actualLength)
{
const byte internationalFormat = 0×91; // telephone/ISDN, international format
const byte unknownFormat = 0×81; // telephone/ISDN, unknown format

// Determine destination address type
byte numberAddressType;
string useNumber;
if (number.StartsWith(“+”))
{
numberAddressType = internationalFormat;
useNumber = number.Substring(1); // strip initial “+” character
}
else
{
numberAddressType = unknownFormat;
useNumber = number;
}

// Determine SMSC address type
byte smscAddressType;
string useSmscAddress;
if (smscAddress.StartsWith(“+”))
{
smscAddressType = internationalFormat;
useSmscAddress = smscAddress.Substring(1); // strip initial “+” character
}
else
{
smscAddressType = unknownFormat;
useSmscAddress = smscAddress;
}

// Encode the user data text
byte dataLength;
string encodedText = EncodeText2(message, out dataLength);
// Encode the SMSC address
string encodedSmsc = EncodeSmscAddress(useSmscAddress, smscAddressType);

// Create the PDU string
StringBuilder builder = new StringBuilder();
builder.Append(IntToHex(0×41)); // message flags:
// msg type=SMS-SUBMIT-PDU,
// validity=relative
builder.Append(IntToHex(0×00)); // Message Reference, 0=set by device
builder.Append(EncodeDestinationAddress(useNumber, numberAddressType));
builder.Append(IntToHex(0×00)); // Protocol ID, 0=SME-to-SME
builder.Append(IntToHex(0×08)); // Data Coding Scheme, 0=7-Bit default
builder.Append(IntToHex(0xAA)); // Relative Validity, 0xA7=24 hrs,0xAA=4days

builder.Append(IntToHex(dataLength));

builder.Append(encodedText);

actualLength = builder.Length / 2;
builder.Insert(0, encodedSmsc);
return builder.ToString();
}

Problem: When text data is from nonASCII language, Using Logica SMPP implementation libarry, sending SMS does not work with standard Latin ISO88591 encoding (Data.ENCISO88591, smpp.datacodingtext = 3). Mobile device shows question mark ?……

My problem solved.
Altough I’m dificult to understanding in English and my program is VB, but I try.. try..and try…
At the end, I solved the problem.

I have tried another message , message is in 2 parts.

part 1 : 0011000C911969832078180000A706050003000201E834BD3C4703
(text : hitesh)

part 2 :
0011000C911969832078180000A704050003000201E1B33A0C
(text : agja)

both parts are send to network successfully but in return I am corrupted message which is not even opening
