Unfortunately I can't actually try your example until next week, as I'm currently out of the office and have limited access.

Are you referring to a Nokia picture message, or an MMS picture message?

The format of the data above does not look like a Nokia OTA bitmap ... what format is it?

504 bytes is not necessarily a problem, but for longer Nokia picture messages, you get 128 bytes per message, so a 504 byte message would require 4 SMS messages. And some phones might have a problem receiving a 4 part message.

i`m referring for Nokia picture message.

The format of the data is bmp format with no header. The format only contain the graphics file.

Can you give me the example hex string for nokia picture message with size 72 * 28 ?

Can you attached to me the bmp file for your example.

I think i my put the header in front of my data.
This is the header "00481C01" It is true?

I'm sorry, but I'm confused.

I still don't understand what the format is of the original data.

Is it Nokia OTA Bitmap format without the header, or is it a regular PC BMP file?

The "00481C01" header would be correct for a 72 (0x48) by 28 (0x1C) monochrome bitmap.

So I'm guessing that you have a Nokia OTA Bitmap without the header.

An example OTB string can be found in the following thread:

Hi Entah,

For simple (non-automated) conversions, you can use the following approach.

The following web site allows you to convert from BMP, JPEG or GIF to OTA bitmap:

The resulting output from that site is a binary OTA file. For a quick and dirty way to convert that file to a hex string, you can use the utility at:

For an alternative to the "teraflops" web site, try ImageMagick (see and specifically ImageMagick's convert.exe can easily convert from GIF/BMP/JPEG to OTA bitmap format, just note that ImageMagick expects the file extension of an OTA bitmap file to be ".otb". So you run "convert image.jpg image.otb" for a simple conversion to OTA bitmap format.
