We present the observational results from a detailed timing analysis of theblack hole candidate Swift J1658.2-4242 during its 2018 outburst with theobservations of Hard X-ray Modulation Telescope (Insight-HXMT), Neutron StarInterior Composition Explorer (NICER) and AstroSat in 0.1-250keV. The evolutionof intensity, hardness and integrated fractional root mean square (rms)observed by Insight-HXMT and NICER are presented in this paper. Type-Cquasi-periodic oscillations (QPOs) observed by NICER (0.8-3.5Hz) andInsight-HXMT (1-1.6Hz) are also reported in this work. The features of the QPOsare analysed with an energy range of 0.5-50keV. The relations between QPOfrequency and other characteristics such as intensity, hardness and QPO rms arecarefully studied. The timing and spectral properties indicate that SwiftJ1658.2-4242 is a black hole binary system. Besides, the rms spectra of thesource calculated from the simultaneous observation of Insight-HXMT, NICER andAstroSat support the Lense-Thirring origin of the QPOs. The relation betweenQPO phase lag and the centroid frequency of Swift J1658.2-4242 reveals a nearzero constant when < 4Hz and a soft phase lag at 6.68 Hz. This independencefollows the same trend as the high inclination galactic black hole binariessuch as MAXI J1659-152.
