  TIC033834484 and TIC309658435 are long-period pulsating subdwarf B star,
which were observed extensively (675 and 621 days, respectively) by the
Transiting Exoplanet Survey Satellite (TESS). The high-precision photometric
light curve reveals the presence of more than 40 pulsation modes including both
stars. All the oscillation frequencies that we found are associated with
gravity (g)-mode pulsations, with frequencies spanning from 80 $\mu$Hz (2 500
s) to 400 $\mu$Hz (12 000 s). We utilize the asteroseismic tools including
asymptotic period spacings and rotational frequency multiplets in order to
identify the pulsational modes. We found dipole (l = 1) mode sequences for both
targets and calculate the mean period spacing of dipole modes ($\Delta
P_{l=1}$), which allows us to identify the modes. Frequency multiplets provide
a rotation period of about 64 d for TIC033834484. From follow-up ground-based
spectroscopy, we find that TIC\,033834484 has an effective temperature of 24
210 K (140), a surface gravity of logg = 5.28 (03) and TIC309658435 has an
effective temperature of 25 910 K (150), a surface gravity of logg = 5.48 (03).
