Installing a Micro SIM/Nano SIM card

A micro-subscriber identity module (Micro SIM) / Nano subscriber identity module (Nano SIM) card
stores information, such as your mobile phone number, contacts, messages and other data that 
gives you access to a mobile network. 

Your ASUS Phone comes with one Micro SIM card slot and one Nano SIM card slot that allow you 
to setup and use two mobile network services without having to carry two mobile devices at the 
same time.

•  This device is designed for use with a mobile carrier-approved Micro SIM / Nano SIM card only.

•  We do not recommend the use of trimmed SIM cards in the Micro SIM / Nano SIM card slot.

•  Turn off your device before inserting a Micro SIM / Nano SIM card.

•  Be extra careful when handling a Micro SIM / Nano SIM card. ASUS is not responsible for any loss or

damage incurred to your Micro SIM / Nano SIM card.

•  Do not insert a memory card into the Micro SIM / Nano SIM card slot! If a memory card happens

to be inserted into the Micro SIM / Nano SIM slot, send your device to an ASUS-qualified service
personnel.

To install a Micro SIM / Nano SIM card:

1.  Turn off your device.

2.  Locate the groove on the bottom-right corner.

CAUTION!  Be careful when you pry open the cover.

3.  Pry the cover loose and then pull the rear cover off.

CAUTION!  Be careful when you pry open the cover.

•  DO NOT use tools like screwdrivers to remove the rear cover.

•  DO NOT pry the micro USB port

4.  Insert the Micro SIM / Nano SIM card into the Micro SIM /

Nano SIM card slot, then put the rear cover back in place. 

IMPORTANT!  Both Micro SIM and Nano SIM card slots support 
4G LTE network band. But only one SIM card can connect to 4G 
LTE service at a time.
