The SIM, an integral part of any GSM terminal device, is a “smart card” that is 
programmed with subscriber information. The user information consists of an 
International Mobile Subscriber Identity (IMSI) number which is registered with the 
GSM/GPRS service provider and an encryption Ki (pronounced “key”). This information 
consists of a microprocessor and memory installed on a plastic card. A SIM card can be 
installed by simply inserting the SIM card in the SIM slot provided inside of the device. 
The SIM slot is located under the battery and the battery door. 
 
To install the SIM card into the Mini-MT device, follow these steps: 
 

1.  Remove the battery cover from the underside of the Mini-MT by pushing the tab 

in the direction that the arrow is pointing.   

2.  Remove the battery. 
3.  Remove the piece of red tape that is covering the battery connectors. 
4.  You will see the SIM card holder in the Mini-MT. 
5.  Slide the SIM card holder to the right, and the door will lift up.   
6.  Slide the SIM card into SIM door.  Make sure the notch on the SIM is aligned 

with the notch in the SIM holder. 

7.  Close the SIM door. 
8.  Slide the SIM lock to the left.  The SIM card holder MUST be locked. 
9.  Place the battery back in the Mini-MT, making sure the connectors are aligned 

properly. 

10. Replace the battery cover. 

 

Note:  The SIM card is not provided with the Mini-MT device. The SIM must be 
obtained from the GSM/GPRS service provider and must be provisioned by the 
operator for data and/or voice. Always take care to protect the SIM. Mini-MT’s 
GSM/GPRS related functionality will not operate without the SIM installed. 

 
 

Enfora is not liable for damages to the Mini-MT when 
inserting a SIM card inside the device.
