We report the electric transport study of the three-dimensional topological insulator TlBiSe2. We propose an analysis procedure which determines the two-carrier transport properties in precision. Magnetotransport properties reveal a multicarrier conduction of high- and low-mobility electrons in the bulk, which is in qualitative agreement with angle-resolved photoemission results [K. Kuroda et al., Phys. Rev. Lett. 105, 146801 (2010)]. The temperature dependence of the Hall mobility is explained well with the conventional Bloch-Grüneisen formula and yields the Debye temperature Θ(D)=113±14 K. The results indicate that the scattering of bulk electrons is dominated by acoustic phonons.
