1.1 SIM Card Types
SIM cards are split into two types:
Dynamic IP SIM cards – the ‘everyday’ kind of SIM card used in mobile
phones. GSM units that use this kind of SIM card can access any data on the
internet but cannot be contacted from the internet. This type of SIM card
should be used for SMS text messaging & Upload/Download via GSM. A data
number will be required to uses Upload/Download.
Fixed IP SIM cards – specialist SIM cards that have a fixed, internet public IP
address which means that in addition to being able to access any data on the
internet they can be contacted from the internet. For Premier Elite
ComGSM this means they can be used for both alarm reporting and
upload/download via IP (GPRS) If a data number is also available, it is possible
to use upload/download via the data number (GSM) instead of the IP address.
SIM cards can have two different phone numbers:
Voice Number: used for voice calls and SMS
Data Number: used for GSM data calls (Upload/Download)
Either of these facilities can be enabled/disabled by the operator.
