Nokia Unlocking Troubleshooting Guide

Have you tried to, or want to, unlock your Nokia Lumia with doctorSIM but are having problems?

Unlocking your Nokia Lumia via IMEI is the fastest, easiest and safest way to be able to use your phone on any network, save on your monthly bill and increase its resale value.

However, occasionally questions arise during the unlock process. Below we have listed the most common ones and what to do in each case:

1. - My Nokia phone displays a “Code Error” message (Nokia and Nokia Lumia).

2. - I am receiving the message “Not allowed” or "Cannot Undo Restriction” (not applicable for Lumia).

3. - My Nokia Lumia prompts for the PUK code (only for Lumia).

4. - The phone accepts the unlock code but has no coverage with the new SIM card inserted.

5. - My Nokia does not connect to the internet.

6. - I have tried everything mentioned above and the unlock code doesn’t work.

7. - I'm not sure if I selected the correct original operator of my Nokia or Lumia.

If you are still unable to unlock your phone, please reply to the email we sent you with the unlocking instructions for further assistance.

 

1. My Nokia phone displays a “Code Error” message (both Nokia and Nokia Lumia).

Insert a SIM card from a network provider different to the one the phone is locked to because this message occasionally appears even though the phone has been successfully unlocked.

If the device isn’t unlocked, reply to the e-mail we sent you with the unlock instructions with the following information:

  • A photograph or screenshot displaying the IMEI number of the phone (type *#06# on the keypad).
  • The network provider your Nokia or Lumia is locked to.

If you don’t know to which network provider your Nokia is locked, or have any questions/doubts, send an e-mail to info@doctorsim.com.

Nokia Lumia: If you received an unlock code with 7 digits, add a “0” to the front of the code. Do the same (add a “0” to the beginning) if the unlock code you received was 19 digits long.

 

2. I am receiving the message “Not allowed” or "Cannot Undo Restriction” (not applicable for Lumia).

These messages indicate your Nokia has run out of unlocking attempts. You can reset the counter by following this tutorial.

Check that you can reset the unlock attempts of your particular Nokia model because this process doesn’t work for the C1 and C2 series.

 

3. My Nokia Lumia prompts for the PUK code (only for Lumia).

If your phone prompts for the PUK code it means you have no more unlock attempts remaining. Contact Nokia’s technical support team to find out if it is possible to reset the unlock attempts counter. If possible, you can then unlock your phone with doctorSIM.

 

4. The phone accepts the unlock code but has no coverage with the new SIM card inserted.

If the phone doesn’t prompt for the network unlock code again it means the phone is unlocked.

Press the Settings icon on your Nokia, find Network operators and then select the Automatic option. If the phone doesn’t register on the network, change to Manual and select the network you want to connect to directly.

If the phone still won’t connect to the network, there are 3 possible reasons:

  • The SIM card inserted doesn’t work with the phone you want to unlock or has not been activated for that network. To rule out either possibility, insert a different SIM card.
  • Hardware failure. We recommend contacting Nokia’s technical support team for assistance as there could be an issue with the SIM card reader, the phone’s antenna or something else.

Blacklists are updated regularly, however, it is possible that very recent changes are not included in the report you receive. If your Nokia is blocked, you must contact the original operator to confirm if the IMEI number has been reported due to loss, theft or unpaid bill.

 

5. My Nokia does not connect to the internet.

To connect your Nokia to the internet, you have to configure the phone for your new network provider. We show you how to do this here:

If you still cannot connect to the internet after the configuration, contact your network provider’s customer support team to check that internet service has been activated on your phone.

 

6. I have tried everything mentioned above and the unlock code doesn’t work.

In this case, reply to the e-mail we sent you with the unlock instructions with the following information:

  • A photograph or screenshot displaying the IMEI number of the phone (type *#06# on the keypad).
  • A photograph or screenshot of where you typed in the unlock code we sent you (do not retype the code).
  • The network to which your Nokia Lumia is locked. If you are unsure, let us know.

 

7. I'm not sure if I selected the correct original operator of my Nokia or Lumia.

To successfully unlock your Nokia or Lumia cell phone via IMEI it is necessary to indicate the correct network provider. If you think you may have selected the wrong network, verify this information by using our Nokia or Lumia Original Operator Check.

Regrettably, we are unable to issue you a refund if any of the information provided in the request form is incorrect and which prevents the phone from unlocking successfully.
