Getting Started: SIM & Memory Cards Installation for Blackphone 2
Blackphone 2 uses a nanoSIM (subscriber identity module) to join your mobile carrier’s network. If you have a microSIM or other size SIM card, you can request a nanoSIM from your mobile carrier.
Blackphone 2 also supports external storage via a microSD card. A microSD card is optional, but lets you expand your device’s storage capabilities. Blackphone 2 supports microSD cards up to 128GB.
SIM and SD cards are installed in a pop-out tray in the side of the Blackphone 2. In your device’s packaging, locate the popper pin, which is attached to the documentation bundle:
Ensure that the phone is face-up on a flat surface, then gently push the tray back into the slot until it is flush with the phone’s edge. NOTE: the top of your nanoSIM (and microSD, if installing one) should be facing UP as you insert the tray back into the phone.
