The slots for a SIM card and a microSD card are placed side by side inside your Razer Phone. To properly insert your SIM card or add a microSD card, follow the steps below.
Step-by-step process
-
Insert the sim eject pin into the sim tray hole then push it in to eject and remove the sim tray.

-
Place your sim card into the sim tray correctly. You may also place a micro SD card into the sim tray if you want additional storage space for your phone. Reinsert the sim tray into your phone and gently push it in until it fits into place.

-
Press and hold the power button to restart the phone. Do this only once the SIM card or SD card has been loaded to ensure the detection of the cards.
