Encrypt Phone
Encrypt the data stored on your phone. Encryption protects the accounts, settings, apps, and files
on your phone, so that people cannot access them if your phone is stolen.
Caution: If you forget your encryption code, you cannot recover the data stored on your phone or
memory card. Encrypting your files can take an hour or more. Leave your phone plugged in, and be
careful not to interrupt the process.
1. Set up a screen lock (see Set Up Screen Lock).
2. From home, tap Apps
3. Tap Encrypt phone to encrypt all personal data on your phone.
Note: Your phone must be fully charged and plugged into a charger to begin the encryption
process. The entire process can take more than an hour to complete.
Set Up SIM Card Lock
In addition to setting up a screen lock, you can require a SIM PIN each time you swap out your SIM
card or restart your phone. The SIM PIN is set up by your service provider.
Caution: If you enter an incorrect PIN code multiple times, your SIM is disabled. Contact your
service provider to unlock and enable the card again.
1. From home, tap Apps
2. Tap Lock SIM card.
3. Enter the SIM PIN set by your provider and tap OK.
When your phone is locked, you must enter the SIM PIN in addition to any other password,
passcode or pattern.
