A person wants to know how to find the model number of their mobile phone. If you are using a Jio phone, go to Settings and then Device Information, where the model number, IMEI number, and other details are listed. If you are using an Airtel 2G phone with Bluetooth, you can turn on Bluetooth and search for the phone from another device; the Bluetooth name usually shows the model number. You can also check it in the Bluetooth settings where the device name is shown or can be edited. If you are using an Android smartphone, go to Settings > About Phone, where you will find complete device information such as the model number, Android version, IMEI number, and software details. However, if you are using an Airtel phone without Bluetooth, it is difficult to check the model number directly, and you may need to refer to the original box or documents that came with the phone.
