In this paper, we study p-adic quasi-Gibbs measures for the three-state SOS model on a Cayley tree of order two. The existence of new translation-invariant p-adic quasi-Gibbs measures have been found. Moreover, the boundedness of the found translation-invariant p-adic quasi-Gibbs measures is proven. Furthermore, we show if (ₛp) =1, s is even and p 1 (mod6), then a phase transition occurs.
