Greetings from Hamari Vaani. My name is Vikas Kumar Gautam from Jodhpur district, and I am 100% visually impaired. To find your mobile phone’s model number, first open the back cover where the battery is placed—there is usually a small label inside with the model number. This applies to most phones like Jio, Airtel, Samsung, etc. If it is not there, check the papers that came with the phone box and ask someone to read them for you. If you still need help, you may contact me at 97215-62354. Thank you.”
