BlackBerry Unlocking Troubleshooting Guide

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

Unlocking your BlackBerry 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 BlackBerry doesn’t prompt for the unlock code when I insert a SIM card from a network provider different to the original.

2. - I get a “Code error” message when I enter the MEP code to unlock my BlackBerry.

3. - The new MEP code still doesn’t work.

4. - My BlackBerry does not connect to the internet.

5. - I get a “Enter Password” message.

6. - How do I obtain the MEP code of my BlackBerry?

7. - What is the PRD

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 BlackBerry doesn’t prompt for the unlock code when I insert a SIM card from a network provider different to the original.

1.1. Check that the device recognizes the SIM card being inserted:

Verify that the phone prompts for the SIM card’s PIN. This number is a security measure your BlackBerry will normally request by default (if activated).

If your phone doesn’t prompt for this security number it means the phone is not recognizing the SIM card being inserted, reason for which it neither prompts for the network unlock code.

Make sure the SIM card is correctly inserted inside the SIM card reader. If that doesn’t solve the issue, we recommend inserting a different SIM card to rule out the possibility that the first SIM card is defective.

 

1.2. Follow the unlock instructions WITHOUT a SIM card inserted:

1. Turn on your BlackBerry.

2. Enter Options/Advanced Options/SIM Card.

3. To access a hidden service menu, type MEPD (use the shift key to type capital letters). (Do not worry if the letters do not appear on screen as you type).

The following list will appear on screen:

      • SIM (Disabled)
      • Network (Enabled)
      • Network Subset (Disabled)
      • Service Provider (Disabled)
      • Corporate (Disabled)

4. To make the BlackBerry request the unlock code, type M E P 2
5. The phone will prompt "Enter Network MEP (10 attempts); enter the code we provided and press OK.

 

VERY IMPORTANT: Do not run out of unlock attempts, if you do the phone will lock permanently to the original network.

 

2. I get a “Code error” message when I enter the MEP code to unlock my BlackBerry.

First, check you have unlock attempts remaining using the unlock method without a SIM card inserted or with a SIM card from a network provider different from the one the phone is locked to (see point 1 above). If the number of unlock attempts remaining is zero, your BlackBerry cannot be unlocked using this method. Initially, all BlackBerry phones have 10 unlock attempts.

If you still have unlock attempts remaining and you sent us the PRD to calculate your unlock code, we can check it and compare it with the MEP of your device.

The MEP is an internal code which allows us to recalculate your unlock code and has the following format: MEP-12345-678.

There are two ways to obtain it:

1. Follow the instructions to calculate the MEP code for your BlackBerry which you can find here: https://www.doctorsim.com/us-en/calculate-blackberry-mep-code.html

2. If you have not installed BlackBerry Desktop on your computer, please install the drivers you can find here: http://tarifas.doctorsim.com/docs/bb_usb_drivers.msi.

If you cannot find your country, please select USA (English).

Please send us those two numbers by e-mail. You will then receive an e-mail from doctorSIM with your new unlock instructions shortly.

 

3. The new MEP code still doesn’t work.

  • Turn on your BlackBerry with no SIM card inserted inside.
  • Enter Options/Advanced Options/SIM Card.
  • To access a hidden service menu, type MEPD (use the shift key to type capital letters).
  • The following list will appear on screen:
    • SIM (Disabled)
    • Network (Enabled)
    • Network Subset (Disabled)
    • Service Provider (Disabled)
    • Corporate (Disabled)

Let us know which of the above options has the lock Enabled.

 

4. My BlackBerry does not connect to the internet.

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

How to connect your BlackBerry phone to the internet

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.

 

5. I get a “Enter Password” message.

After typing the PIN for a SIM card from a different network provider and prompted to “Enter Password” (attempt X of 10), type your security password. This is a personal password known only by the owner of the phone and should be typed before being prompted for the unlock code (MEP).

 

6. How do I obtain the MEP code of my BlackBerry?

The MEP is an internal code which allows us to recalculate your unlock code and has the following format: MEP-12345-678. If you need to know the MEP code of your BlackBerry click here: https://www.doctorsim.com/us-en/calculate-blackberry-mep-code.html

Once you’ve sent us this information, you will shortly receive the correct unlock code to successfully unlock your BlackBerry.

  • If the program used to obtain your MEP code doesn’t recognize your BlackBerry, you will need to follow the steps again. First, press “Read Phone” and then connect your BlackBerry to your PC so the program can read the IMEI number and MEP code.
  • Also, confirm to us the IMEI number (type *#06# on the phone’s keypad).

There are two ways to obtain it:

1. Follow the instructions to calculate the MEP code for your BlackBerry which you can find here: https://www.doctorsim.com/us-en/calculate-blackberry-mep-code.html

2. If you have not installed BlackBerry Desktop on your computer, please install the drivers you can find here: http://tarifas.doctorsim.com/docs/bb_usb_drivers.msi.

If you cannot find your country, please select USA (English).

Please send us those two numbers by e-mail. You will then receive an e-mail from doctorSIM with your new unlock instructions shortly.

 

7. What is the PRD?

The PRD is an additional identifier which allows for obtaining the unlock code for your BlackBerry with greater speed and reliability. Your BlackBerry's PRD is located on the sticker under the phone's battery.
