Message Fragmentation

Message Fragmentation
Messages are limited to a length of 50 kB. Larger messages will be split into fragments. On the
phone side, the threshold is defined by the
maxItems
attribute of the
Message
element. When
the number of data items to be contained in a message exceeds the number given here, or the
message reaches the 50 kB limit, the message is split up. Alternatively, the provisioning service
can decide to construct a message as multiple messages.

could have been driven both by the phone or by the provisioning service.
