To unlock your UMX phone's PIN, you can try either of the following options:
- Enter the correct PIN, as you may have set it previously.
- If you have forgotten the PIN, try entering it incorrectly multiple times. This should prompt a "Forgot PIN" or "Reset PIN" option. Tap on it, and follow the instructions to unlock your phone, which may involve verifying your Google account or using your phone's backup PIN/password.
- If none of the above methods work, it is recommended to contact UMX customer support for further assistance, as they will be able to guide you through the specific steps to unlock your phone.
