Sending messages in udh & udp hex format

If you require the ability to specify sms headers for sending concatenated messages or vCards for example, you can make use of our UDH gateway. This gateway is accessible via HTTP Post only at the folllowing address:

http://gw1.aql.com/sms/gw-udh.php

Variables (via HTTP Post ONLY)

username - aql username
password - aql password
destination - destination number (ie 447740..)
originator - not necessary, will use account default if not specified
udh - User Data Header in hex format (no plain text allowed)
data - User Data Portion in hex format (no plain text allowed)

The gateway only accepts single sms messages, so larger messages must be split before they reach our gateway.

Example header/data set:

["udh"]=> string(21)
"0605040B8423F0"

["data"]=> string(195)
"01060403AE81EA02056A0045C60b03687474703a2f2f7777772e612d712e636f2 e756b2f0011033240736d7332656d61696c000801035465737450757368000101"
