Ramya has said that the first film offered to her was Ninagagi that eventually starred Radhika.[2] She was then supposed to make her debut in Puneet Rajkumar's first film Appu, for which she, however, was not selected. She made her acting debut in the 2003 Kannada-language film Abhi, alongside Puneet Rajkumar, which became a commercial success. The same year, she had another release in Kannada with Excuse Me, which also did well at the box office, and also stepped into Telugu filmdom with the film Abhimanyu.
In 2004, Spandana debuted in the Tamil film industry, also under the name Ramya, with the film Kuththu alongside Silambarasan Rajendar, which managed only a mediocre run at the box office as did her next Tamil film Giri. Her debut film, however, gave her the name 'Kuthu' Ramya, by which she was then popularly known in Tamil Nadu. She had two releases in Kannada as well, Ranga S. S. L. C. and Kanti, out of which the latter, a love story set against the backdrop of borders and language issues, was declared a major success. In 2005 she had four releases, all being Kannada films, with the latter three films Aakash, Gowramma and Amrithadhare becoming major box-office successes, whilst also garnering critical acclaim for Ramya's performance and establishing her as a leading actress in Karnataka.
