The User Data Header (UDH) is a part of the Short Message Service (SMS) protocol that allows additional information to be included with a text message. UDH is commonly used for various purposes such as concatenating long messages, adding special characters, creating binary messages, and enabling advanced features like ringtone downloads and multimedia messaging. By utilizing UDH effectively, telecom providers in the UK can enhance the user experience, deliver targeted marketing campaigns, and facilitate interactive communication with customers.
