PIN and SMS Messaging

A Personal Identification Number (PIN) uniquely identifies each 

BlackBerry device on the network. If you know the PIN of another 

BlackBerry device user, you can send a PIN message to that person. 
PIN messages are not routed through email accounts so you do not 

need an email address to send a PIN message.
When your PIN message is delivered to the recipient, in the messages 

list, a D appears with a check mark beside the PIN message.
To find your PIN, from the Home screen, click Options. Click Status.

SMS is the abbreviation for "Short Message Service". In short it is a 

means to send a text message via the cellular network to a cell phone. 

The message has a limitation of 160 characters.

An unopened SMS message appears in the messages list with a closed 

italic envelope icon. After you open the message, the closed italic 

envelope changes to an open italic envelope as displayed here.
