The Thais, nine women and 16 men, were handed over at the Ban Klong Luek border checkpoint in Sa Kaew's Aranyaprathet district.
They were arrested by Cambodian police along with four Taiwanese men, at the request of Thai police, for allegedly using the Cambodian base to call Thais to deceive them to wire money to their accounts.
They were arrested at a rented house in Phnom Penh on February 16.
The Thais had been sentenced to two years in jail each and the Taiwanese three years in jail. They will serve their remaining jail term in a Thai prison.
The Cambodian authorities also handed over the four Taiwanese to Taiwanese authorities.
