| as others have surmised (correctly) the 'phone doesn't tell the network you are typing a text message until you send it. A complete text message up to 140 characters is squeezed into a single signalling message to the network. Hence the network does not and cannot know that you have part-typed a text message.
There are other messages when you connect to a different network, move area, turn phone on or off etc, which is obviously needed by the home network in order to actually work (ie in egypt if it's an egyptian phone), , but "it's xx o-clock, why hasn't she called?" is a more probable explanation, unless he is a proper switching engineer working and working on the particular network elements, in a maintenance role and abusing his position.
