    RE: about the size of Nokia 3310 operator logo

    The User Data part of an SMS is limited to 140 octets. The User Data Header takes 7 octets (1 length-of-user-data-header, 1 address, 1 address-length, 4 address itself). The actual bitmap part of a 72x14 OTA bitmap takes 9x14 = 126 octets. The OTA bitmap headers, when constructed according to specifications, take 9 more octets (1 OTA bitmap-version-number, 3 MCC+MNC, 1 Linefeed, 1 InfoField, 1 width, 1 height, 1 depth). (See Table 3a of question 9.) This makes a total of 142 octets - too long by an annoying two octets! This means that according to the specifications, any operator logo would require two SMS messages.

    There is a workaround which allows these logos to be sent using only one SMS. This workaround currently works with Nokia phones, but no support for single-message logos can be promised to nor should it be assumed by developers. It must be stressed that functioning of single-message logos in future Nokia terminals or terminals provided by other vendors supporting Smart Messaging cannot be guaranteed. (Note that a 72x13 OTA bitmap will fit into a single SMS message and still comply with specifications! These types of bitmaps will be guaranteed to be compatible, whereas a 72x14 logo sent using the method described below will not.)

    In any case, the workaround for a 72x14 logo is such that the two octets on either side of the MCC+MNC octets are left out completely. These octets are the OTA bitmap-version-number and the linefeed character.
