2.9. SIM Card
A SIM card must be inserted into the C12 instrument for the GSM
communication to work. We suggest the use of Sigicom branded SIM
cards. The SIM card must have an active GSM subscription, including
GPRS access.
Note! The PIN-code lock of the SIM card must be deactivated before
using the SIM in C12.
If the operator cannot deliver a SIM card with the PIN deactivated, it can
be done by placing the card in a normal mobile phone and locate the
security settings, where it can be deactivated.
Also, the operator should provide the proper APN for the GPRS
connection. Normally the APN is enough, but in some cases, also the PPP
user name and password is needed for the GPRS connection.
Do not use a secondary SIM card connected to the same subscription.
These sometimes give problems.
For support and traceability reasons please use a normal mobile
subscription. A pre-paid subscription is not recommended. Also, keep
track of the number code (SIM ID) printed on the SIM card, and the serial
number of your C12 instrument. This will be of help for identification, if
you need support from the operator.
Note! Internet access is always included in a GPRS subscription, but often
there are lots of different models of how the operator charges the data
traffic. First look at the operator’s information about ‘Telematics’, ICT or
M2M subscriptions before signing a subscription.
In Figure 2-1 you can see how the SIM card is inserted from the left-hand
side.
