List of All OnePlus Secret Codes and Service Codes (2023)

This post will provide a comprehensive list of all the OnePlus secret and service codes. Although you may primarily use the Phone Dialer for making calls, it has additional functionalities beyond that. Your OnePlus device contains numerous hidden codes that can be activated or enabled directly from the dialer. Some codes display hardware and software information, while others can reset your device. Additionally, you can access an Engineer Mode, Test Mode, and hidden menus through the dialer.

There are many codes specific to carriers like T-Mobile and AT&T. However, trying out all of them is not recommended just because they have some benefits. You should read their descriptions carefully and only use the ones you need. Additionally, some codes only work on certain OnePlus devices and may not work on others. It is important to confirm if the code applies to your specific device before trying it out.

Also, some of these codes might be region-specific as well. Unfortunately, the only way to check them is to try them out if they work out as intended, well and good, otherwise, move over to the next one. As far as the activation of these codes goes, it might work on either of the two days. While some get executed automatically after entering the last digit, for others, you might have to hit the Call button. With that said, here are all the OnePlus Service Codes and Secret Codes that you should check out. Follow along.
