 Operator Logos sit in the middle of the screen and disappear when coverage is lost.The original intent of Operator Logos was to allow a Network Operator or MVNO to replace the name of their network (as stored on the SIM card) with their graphical logo, but human nature being what it is, people now usually get one that represents them rather than their network.There is a workaround that allows a standard size Operator Logo to be sent as a single message, however, compatibility with newer or non-Nokia phones is uncertain.
