IMPORTANT: 

Use a standard nano SIM only. 

Don’t cut a micro or regular SIM card and insert it into 

the nano SIM slot. It’s thicker than the standard nano SIM 

card and may get stuck in the slot. 

Don’t disassemble any part of the phone. 

Don’t try to open the phone or remove the battery by force. 

This may damage the phone or its electronics and will 

invalidate the warranty. 

Don’t throw the tray away.  

You need it to insert your nano SIM and microSD™ cards. 

1.  With the phone facing 

up

insert the tip of the tray 

eject tool that came in 

the box (or a small bent 

paperclip) into the tray 

eject hole. 

Push the tip all the way 

into the hole until the 

card tray ejects and then 

gently pull the tray out.

2.  With the gold contacts 

facing 

down

, place your 

nano SIM and microSD 

cards into the SIM and 

SD holders of the tray. 

Make sure to align the 

cut-off corner of the 

nano SIM card to the 

notch on the holder.
