Blackphone, the first privacy-driven mobile device, has begun shipping.

For $629, global customers will receive the phone, which operates on a custom Android operating system called PrivatOS, according to the company's website. Pre-ordered phones are being shipped now. However, additional orders are no longer being accepted. Details are to come about when additional phones will be available.

The phones come unlocked and with multiple pre-installed privacy apps available. ‘Silent Phone' and ‘Silent Text,' for example, encrypt phone calls and texts, respectively.

Additional features include a remote wipe function, as well as secure file transfer and storage.

The phones are compatible with any GSM carrier, including T-Mobile and AT&T, among others.
