Even the advertisement's jingle was sung by Chowdhury. Though he never had any formal singing lessons, he is gifted with the talent to sing. "I always listened to Hemanta Mukhopadhdhay and Bhupen Hajarika and sang those songs to myself; I told Mostofa Sarwar Farooki bhai to give me a chance to sing the jingle because I really thought that my voice would suit the song. Ayub Bachchu and Mostofa Sarwar Farooki then listened to my singing and later let me know that my song had been selected." Chowdhury later won the Meril-Prothom Alo award as the best model 2006 for this commercial. Chowdhury came into the spotlight for the first time as a model in the commercial of Grameenphone which became immensely popular at that time. Pother Klanti Bhule - a very popular song of Hemanta Mukherjee attracted some more attention onto the advertisement. Eventually, that advertise brought him the prestigious Meril-Prothom Alo award in "The Best Model - Men" category in 2005. The commercial was directed by Mostafa Sarwar Farooki, with whom, Chowdhury worked with on the serial 'Talpatar Shepai'.
