About compression
Compression is designed to reduce the size of your BlackBerry® smartphone data while maintaining the integrity of that data.
When compression is turned on, your smartphone compresses all smartphone data, including messages, contacts, calendar
entries, tasks, and memos. You should keep compression turned on.
If both compression and encryption are turned on, your smartphone compresses smartphone data before encrypting it.
About file encryption
File encryption is designed to protect files that you store on your BlackBerry® smartphone and on a media card that can be
inserted in your smartphone. You can encrypt the files on your smartphone and on your media card using an encryption key
that your smartphone generates, your smartphone password, or both.
If you encrypt the files using an encryption key that your smartphone generates, you can only access the files on your media
card when the media card is inserted in your smartphone. If you encrypt the files using your smartphone password, you can
access the files on your media card in any smartphone that you insert your media card into, as long as you know the password
for the smartphone.
Turn on encryption
To encrypt data on your BlackBerry® smartphone, you must have set a password for your smartphone.
