Android users are known to be technology explorers. The flexibility that Android offers allows its users to take full advantage of the operating system's capabilities. Therefore, it is not really a surprise for many HTC users to learn that there are HTC secret codes to unlock hidden features and unlock SIM-bound devices.

Do take note that it is not the manufacturer's intention to keep these feature hidden from users; they just want to simplify everything about the devices for common or simple users so that they are not confused or bothered by the technical stuff. They are easily accessible via dialer codes in case you want more control over your HTC devices.

Part 1: Secret Codes for Hidden Features

They are two types of secret codes: general codes and manufacturer-specific codes.

These codes allow users to do many things on their devices so that they can maximise the power of an Android machine. Here are some of them for you to try your hands on.

General Codes

You can use these general codes on any Android devices regardless of their manufacturer, model or make.

Do take note that the list of HTC phone codes above is not exhaustive and they are probably more lurking around the interwebs. Before you use them, I would like to caution you about the possible harm that they may cause your device; make sure that you take all the necessary precautions (like backing up your htc phone) before you dial any codes.

Part 2: HTC SIM Unlocking Code Generator

From the big list of HTC secret codes above, you may notice that there is no code to SIM unlock your HTC device being listed---this is perhaps because there is none.

So what should you do if you are upset with your mobile network provider's service but your contract with them is still active and you are not willing to pay them an exorbitant amount to exit their bad service?

The best and easiest way to perform a SIM unlock procedure on your HTC device (or on any device, for that matter) is to use a paid SIM unlock service that will give you the unlocking codes you would need to free yourself from the evil clutches of your mobile network provider. There are many companies that are offering this service---one of the best is Dr.Fone - SIM Unlock Service.

Select the make and model of your device (in this case HTC) as well as the country and mobile network provider that your device is tagged to. The system will automatically show you the price you need to pay; it varies according to the information you have provided (note: remember to input the correct information because even though the make and model may be the same, the "lock" is unique to the country and mobile network service provider). Additionally, the guaranteed delivery time of the instructions and unlocking code varies according to the country and mobile network provider; everything will be made transparent to you when you are completing the request form. If you need them faster, you can opt for that too.

Once payment is confirmed, your request will be processed and the Dr.Fone - SIM Unlock Service team will send you an email.
Follow the step-by-step instructions and use the code delivered by the email to ensure the success of the SIM Unlock process.

SIM Unlocking can be performed on any mobile device and now that you know that you can do so by yourself, you do not need to worry about any exorbitant fees by your mobile carrier. While there are many benefits of HTC phone codes, you also need to know that there are some disadvantages that come with unlocking your device.

Do share this with your family and friends so that they can equip themselves with the same knowledge.
