GPRS / GSM configuration
GSM PIN code
The PIN code of the SIM card. This is were you enter the PIN code of the SIM card. It is possible to change
the PIN code by placing the SIM card in a mobile telephone and entering a new code.
Roaming
It is possible to activate roaming in the AlphaCom XL. In the default settings roaming is disabled. Roaming
is only necessary when using a GPRS provider that does not have its own GSM/GPRS network but uses
networks from other providers. Roaming however does have a certain risk. When installing an installation
close to the border, roaming can cause the GPRS module to connect to GSM/GPRS providers just over the
border and thus causing high calling costs. Make sure you clearly inform your customer of the risks involved
when using roaming !. We advise to use a local GSM/GPRS provider that has its own network.
