These user instructions
The GSMDH modem is used to deliver text messages only.
SIMs
A Pay as You Talk SIM can be used but the number can be voided by the network provider if the SIM
is not used to make a call within 90 days (e.g. Vodaphone). For this reason a contract SIM is
preferred.
Darca Heritage Version 2 does not provide any maintenance messages to prevent this.

Some SIMs (e.g. Orange) may be supplied with a PIN. To check if a PIN is needed, insert the SIM
into a mobile that is not locked to another network, and check if a PIN is requested. The PIN should
have been issued when the SIM was obtained. Ensure the PIN is disabled for this application. (You
will need to use a mobile in order to disable the PIN).
