To identify what type of phone this is, some effective steps include:

1. Checking the phone's settings menu for the model name. For iPhones, go to Settings > General > About to see the "Model Name" and "Model Number." For Android phones, go to Settings > About Phone and look for "Model" or "Device Name."
2. Dial *#06# on the phone to display the IMEI number, then use an IMEI lookup service online to find the exact phone model.
3. If the phone is off or locked, check for physical markings such as model numbers on the back of the phone, inside the SIM tray, or original packaging.

These methods help determine the make and model accurately without specialized tools or apps. If there is a phone image or additional details about the phone available, sharing those would enable a more precise identification. Otherwise, using the steps above is the best way to find out the phone type.
