HTC Unlocking Troubleshooting Guide

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

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

2. - My HTC is locked to T-Mobile or MetroPCS and does not prompt for the unlock code.

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

4. - My phone prompts for the unlock code but I get an error message when I type it in.

5. - I'm not sure if I selected the correct original operator of my HTC.

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 HTC 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 HTC 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. The SIM card is recognized but nonetheless doesn’t prompt for the unlock code:

  • Check the phone works with the new SIM card inserted. If so, your HTC is unlocked.
  • We recommend restoring the phone to its factory settings. This process eliminates possible errors preventing the phone from prompting for the network unlock code. You can find the option to restore to factory settings under Settings on the phone’s menu.

1.3. If having tried all of the checks above and the phone still doesn’t prompt for the unlock code, it means your HTC cannot be unlocked via IMEI. If you have any questions and/or doubts, send an e-mail to info@doctorsim.com.

 

2. My HTC is locked to T-Mobile or MetroPCS and does not prompt for the unlock code.

Check you have the Device Unlock Application installed on the phone.

If so, you must make your request using our Device Unlock App Service by clicking on the link below and selecting either T-Mobile or MetroPCS:

Unlock HTC Device Unlock App

 

3. 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 HTC, 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 HTC’s technical support team for assistance as there could be an issue with the SIM card reader, the phone’s antenna or something else.
  • The HTC’s IMEI number has been blacklisted due to loss, theft or unpaid bill by the original operator. To check if your HTC is Blacklisted click on the link below:

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

  

4. My phone prompts for the unlock code but I get an error message when I type it in.

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).

Also, check that your HTC hasn’t been rooted or modified at some point in the past. If your phone’s software has been modified, we recommend restoring the phone to factory settings so it responds correctly to the unlock instructions.

 

5. I'm not sure if I selected the correct original operator of my HTC.

To successfully unlock your HTC 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 HTC 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.

Select either "Original Country Unknown" or "Network Operator Unknown or Not in List" if you prefer not to use our IMEI phone check and are unsure to which network your HTC is locked.
