Nokia Operator logos are one of the more complicated of the Nokia Smart Messaging formats. To send a Nokia Operator logo, you must have a hex string value for an OTA Bitmap, as defined by the Nokia Smart Messaging specification. The hex string format represents two characters for each binary byte of OTA Bitmap data. Documentation of the OTA Bitmap data format is beyond the scope of this document. You must also know the Mobile Country Code (MCC) and Mobile Network Code (MNC) values of the network operator to which the recipient is subscribed. A link on the form provides more information on MCC and MNC codes, and a pointer to the URL http://www.gsmworld.com/roaming/gsminfo/index.shtml, from which you can look up the MCC and MNC codes of various network operators.

For those who wish to send Nokia Operator logos programmatically via the Now SMS/MMS Gateway, note that this form includes the following hidden fields which are included as URL parameters when submitting the message to the server:

UDH = 06050415821582

PID = 0

DCS = F7

JavaScript in the HTML converts the MCC and MNC codes into the format required by the Nokia Smart Messaging specification, and combines them with the OTA Bitmap data to create a valid operator logo message in the URL “Data” parameter submitted by the form.
