How do I insert an SD card and what is the format?

1. The location of the SD card slots is behind the SIM Card and SD cover on the rear of the device and can be accessed by pressing the card cover latch.
2. The SD card location above the SIM 2 card slot, the Micro SD card needs to be inserted as per drawing with the gold contacts facing down. Do not force the card in or out of the device as this could result in damage.
Note:
The CAT S60 does not support ExFAT format.
With Marshmallow, the SD card becomes by design expandable memory for your device, with this comes restrictions with use of the SD card in devices other than your CAT S60. Once you have formatted the SD card with your device then to use in a separate device, such as a PC, will require re-formatting of the SD card which will erase the content. with Android Marshmallow, apps and the data they use can now be seamlessly stored on an external microSD card without having to be explicitly put there by the user.
