4.2.2 SIM Card Slot
Netbiter SIM Card
When using a Netbiter SIM card (supplied by HMS), the card is configured ready for use, and the PIN
code security function has been disabled.
SIM Card - Other Network Operator
To use any another SIM card, you will need to know the following information:
• The phone number for the SIM card.
• The Access Point Name (APN) to connect to, as well as the user name/password - if this is re-
quired by the network operator.
The PIN code security function must be also disabled before mounting the SIM card. To do this: insert
the SIM card in a regular mobile phone and follow the instructions provided by the manufacturer.
Insert the SIM Card
Open the SIM card holder by pressing the small button at the
left of the SIM card slot, with a small screwdriver, pen or sim-
ilar.
When the SIM card is in place, and the required inputs/outputs
have been connected, Netbiter EasyConnect EC220 can be
powered up. The rest of the configuration is done via Netbiter
Argos. See page 40 for further information.
