I suppose your goal is not to send it to a Nokia phone... And that the 
phone you send it to supports EMS images of this size...

252 hex digits, but they represent 126 bytes.

Nope, 129. Also let us know when you find a network and a phone which 
support 256-byte messages!

Nope, 127.

Quite normal. Of course, if your logo was bigger and did not fit in a 
single message (140 bytes total), you would need to split it in several 
parts and add SAR IEs.
