Greetings to everyone at Hamari Vaani, including all the listeners and volunteers. My warm regards to all. I would like to ask Mr. Munnalal Bharti a question. If a smartphone is being distributed through a camp or any organization, what is the validity requirement for the residence certificate? Is a residence certificate issued within the last three years considered valid, or are older certificates also accepted? Please let me know as soon as possible. If you prefer, you may also inform me by phone. My contact number is 62637....
