Send alphabets in USSD string through STK

Hi All,

I am able to send numbers in USSD string .But when I am trying to send alphabets in ussd string I am not getting any response.

Please suggest how can we send alphabets in USSD String.

Is there any configuration at HLR side to handle this problem or there is problem with my code-

ph.init(PRO_CMD_SEND_USSD, (byte)0, DEV_ID_NETWORK);

ph.appendTLV( (byte)(TAG_ALPHA_IDENTIFIER), smsF, (short)0, (short)smsF.length);

ph.appendTLV(TAG_USSD_STRING, DCS_DEFAULT_ALPHABET, bytes, (short)0, (short)bytes.length);

Thanks & Regards

vikas
