3.2.5 SIM Card
The INSYS GSM small requires a SIM card from a GSM provider for operation. The SIM
card is the identification towards the network provider.
The slot for the SIM card is on the bottom of the INSYS GSM small. Push the sunk yellow
button above the card slot to unlock and pull out the insert. The visible contacts of the
SIM card must face the top, when inserting the SIM card into the holder. Push the card
holder back into the card reader (contacts of the SIM card to the left), until the card
holder is flush with the housing (see figure in Chap. 4.2)
The card holder (slot) is secured against falling out.
Note: Only 3V cards may be used.
Attention! Change the SIM card only when the device is switched off, otherwise the
SIM card could be damaged.
The GSM provider has to enable the desired services for the SIM card. A card can be
enabled for voice services (traditional GSM cards for mobile phones) and data services at
the same time. The following cards and contracts are normally available:

Note: In general, different phone numbers are assigned to the different services.
The GSM network does not automatically switch e.g. the call of a modem to
the voice number to the data number.
3.2.6 Antenna Interface
The antenna connector at the front of the INSYS GSM small is of type FME (male).
All commercial GSM antennas with a female FME connector can be used as antennas.
Ensure that the frequency band corresponds with the one of the provider when using
single band antennas (900 MHz or 1800 MHz).
