Narrative:

The sju RNAV SID 5-10 page states in bold print: after takeoff; contact departure control on assigned frequency. We understood this to direct an automatic switch after takeoff. Upon contacting departure; we were told to return to tower frequency. Tower controller asked why we changed frequencies without being told. I stated directions in SID departure procedure. Tower stated to wait for frequency change in future. Tower then switched us to departure without further comment. I reviewed other sids and this verbiage was not included. Many international locations have this directive so it was confusing to read and then be reprimanded for doing as SID directs.
