By default the Telus Diamond will disconnect data connections after 600 seconds. This does NOT mean your data connection will turn off (as seen in the connection manager) but will be idle until needed again.Every time you terminate any programs using the data network the phone will still have an active connection for 10 min (unless you shut off the phone).
