Mast Mobile today announced that its service is now supported on Samsung Galaxy S7, S7 Edge, S6, and S6 Edge smartphones with Android 6.0 Marshmallow. Mast originally launched in February, but was only available on the iPhone.

Mast's pitch is that it allows two phone numbers to work on the same device, essentially turning a single-SIM device into a dual-SIM device. The numbers have independent messaging and voicemail boxes, and can be used with the device's native phone and messaging apps.

The company also announced that it received a strategic investment from Samsung and it is launching the first commercial integration with Samsung's KNOX security platform.
