What is a Device Unlock
Hi, huge problem, I changed my SIM to a different SIM provider, and when I opened my phone again, I got the message enter your privacy protection password to unlock. I remember turning on anti-theft settings when I opened my mobile for the first time but have no idea what the password was. This method will erase the content from your phone. As of Android 5.0, Google has removed the ability to bypass the lock code without wiping the content. You'll be able to get back into your phone, but you will lose any data (such as music and photos) saved to the device. A device unlock is not a security feature, for security locks see: Device lock and security troubleshooting; SIM card and PUK errors. Check unlock status. Log into your MyT-Mobile account using a web browser. Note: This option is not currently available on the T-Mobile app. Click Account from the top left of the screen.
