The high frequency quasiperiodic oscillations (QPOs) in the X-ray spectra ofthe millisecond pulsar XTE J1807-294 are under consideration. By application ofthe relativistic precession (RP) model an attempt is made to approximate theobserved frequencies as well as to assess the mass and the angular momentum ofthe object. The obtained mass is too high for a neutron star.
