STK send sms on nokia 6021 results in 0x32

Question

Hi,
I am developing a STK application that sends an SMS. On the emulator and nokia 6680 everything goes fine. However, the nokia 6021 returns a resultcode of 0x32 ("command data not understood by ME").
What could be the problem ???
Thanks, Eric
This is the SMS_TPDU (number is Z-ed out):
public byte[] tpdu = {
      //                                           |
      (byte) 0x11,  //  TP-RP  TP-UDHI  TP-SRR  TP-VPF       TP-RD  TP-MTI
      //                0=no   0=no     0=no    00=no field   0     01 (submit)
      //                reply  usr data 1=yes   10=relative
      //                path   header   status  01=enhanced
      //                       indicat  report  11=absolute
      //                                        validity period format
      (byte) 0x00,  // TP-MR (message reference)
      (byte) 0x0B,  // address length
      (byte) 0x91,  // TON
      0x13, 0x16,(byte)0xZZ,0xZZ, (byte)0xZZ, (byte)0xfZ, // number
      (byte) 0x00,  // TP-PID protocol id
      (byte) 0x04,  // TP-DCS (8bit data =0x04)
      (byte) 0x0B,  // TP-VALIDITY-PERIOD 0x0B=1H  0xAA=4 DAYS
      (byte) 00,    // TP-USER DATA LENGTH
      (byte) 1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20, // 140 bytes
      (byte) 1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,
      (byte) 1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,
      (byte) 1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,
      (byte) 1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,
      (byte) 1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,
      (byte) 1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,
      (byte) 1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20 // 20 bytes overflow
  };and the code (writePos is the length of the the TPDU):
      ProactiveHandler hdlr = ProactiveHandler.getTheHandler();
      hdlr.clear();
      hdlr.init(PRO_CMD_SEND_SHORT_MESSAGE, (byte)0x00, DEV_ID_ME);
      //           bit 0: 0=no pack 1=ME packs    ^^^^
      // alpha indentifier with no data indicates that ME should not show anything
      hdlr.appendTLV(this.TAG_ALPHA_IDENTIFIER, nullAlphaIdentifier, (byte)0, (byte)nullAlphaIdentifier.length );
      tpdu[OFFSET_USERDATA_LENGTH]= (byte) (writePos-OFFSET_USERDATA_BEGIN);
      hdlr.appendTLV(this.TAG_SMS_TPDU, tpdu, (byte)0, writePos);
      byte r = hdlr.send();

Does the 6021 actually support the Send Short Message proactive command ? Nokia's are notorious for having inaccurate terminal profiles.
However the 6021 teminal profile
DF F7 FF FF 1F 00 00 DC 5D 00 00 00 00 05 0F 80 00 00 00
would suggest that it is meant to support it.
