Munawwar Sultana started her career as radio and playback singer probably around mid 40s. She used to take musical lessons from Master Ghulam Haider. She, along with the music composer G.A. Chisthi, is mostly credited for bringing the dead film industry of Lahore-Pakistan back to life.

Her songs for Punjabi film Pheray (1949) Mainou rab di sohn teray naal pyar ho gaya and Wey akhiyan laawein na (a duet with Inayat Hussain Bhatti) composed by G.A. Chishti were the main reasons for the success of the film. The movie went on to became first Punjabi Silver Jubilee film of Pakistan. Similarly, her songs composed by Mubarak Ali for film Do Ansoo (1950) were instrumental in securing the future of Urdu films as Do Ansoo was the first Urdu Silver Jubilee film of Pakistan.
