 
Text messages
Your phone can send and receive multi-part messages, which consist of several 
ordinary text messages (network service). Invoicing is based on the number of 
ordinary messages that are required for a multi-part message.
You can also send and receive text messages that contain pictures. Each picture 
message is made up of several text messages. Therefore, sending one picture 
message may cost more than sending one text message.
Note: Picture message function can be used only if it is supported by your network 
operator or service provider. Only phones that offer picture message features can 
receive and display picture messages.
