Google is removing the hassle of remembering SIM codes on Android 17

Google is working on a feature in Android 17 that could quietly remove one of the most annoying security steps on your phone. If you use a SIM PIN, you may soon not have to remember it or enter it every time you restart your device.

According to Android Authority, the feature, called automatic SIM lock protection, first appeared in Android 17 beta and is now live in the latest Canary build.

How does automatic SIM lock protection work?

A SIM PIN is different from your phone’s unlock PIN. It protects your SIM card itself and is required when you reboot your phone or insert the SIM into another device. Without it, your SIM cannot be used for calls, texts, or mobile data.

To set up the new feature, you enable Automatic PIN management, confirm your identity with your passcode or biometrics, and then enter your SIM’s current PIN. If you have not set one, you can use your carrier’s default code, which is usually something simple like 0000, 1111, or 1234.

You can find it by heading to Security and Privacy, > More security & privacy > Protect SIM card. You can also view the stored PIN inside the settings by using the ‘Show Android managed PIN’ option.

Once this is done, Android takes over. When you restart your phone and unlock it, the system automatically enters the SIM PIN for you.

Why does this matter?

The biggest issue with SIM PINs has always been convenience. You are already juggling multiple passwords, so remembering another code feels like a hassle. Automatic SIM lock protection removes that burden while keeping the protection in place.

Importantly, the SIM PIN still works as intended if your card is moved to another phone. In that case, the PIN must be entered manually, which helps protect your number from misuse in case of theft.

That makes this feature especially useful if you are worried about someone accessing your calls, messages, or two-factor authentication codes. It is a small change, but one that could make SIM level security more practical for everyday use.
