Unlock your Nokia with an alternative method to using the IMEI number

doctorSIM is committed to helping you unlock your phone every step of the way

Follow the steps below to unlock your Nokia via USB

If you have received a confirmation e-mail with a link to this page, simply follow the instructions below to unlock your Nokia.

If you haven’t requested your unlocking code yet, you can search for the make and model of your phone, and network operator here.

To start the process of unlocking your Nokia, you must first download this program which will read a reference number located inside your phone that doctorSIM requires to generate an unlocking code for that particular phone.

You will also need the following:

  • A USB cable for your phone
  • A computer with Microsoft Windows
  • Nokia PC Suite installed on your computer
  • Three minutes of your time


  1. Once you have downloaded the program, unzip it and open the “doctorSIM_Nokia_USB_Reader” folder and search for “Hashreader.exe” to run the application.

    If you don’t have a file decompressor, you can use this one.
    If your antivirus software doesn’t allow you to install the program, disable it temporarily.

  2. The program will open when you run “Hashreader.exe” from the unzipped folder.

  3. Now connect the phone to the computer using the USB cable, select the PC/OVI Suite mode on the phone and wait for the program to detect the phone. As you can see on the screenshot below, confirmation will appear on the bottom of the screen.

  4. Press the “Read Hash" button.

    Occasionally, you may be asked to remove the battery and disconnect the cable. The full procedure is as follows:
    - Disconnect cable
    - Remove battery
    - Wait 5 seconds
    - Reinsert battery
    - Reconnect cable
    If the program doesn’t run when you reconnect the cable, press the phone’s power button.
    Depending on the model, you may be asked to perform this procedure twice.
  5. After a minute more or less, the process will be completed. You will then see the following on screen.
  6. Three files will appear under “Local_calc” in the “doctorSIM_Nokia_USB_Reader” folder:
  7. Select the file with your IMEI number as its name and the extension .bcl (e.g. 011950004980028.bcl), and follow the instructions on the link we have sent you to upload the file.
  8. You will receive your unlocking code and instructions in approximately 48-72 business hours.
