Warning SMS
The information about SIM charge and expiration date are not saved in the SIM card but are managed
by the network operator; the analyzer can not get directly the information.
To prevent an unnoticed discharge of the SIM card, the user has to configure manually (accordingly
with the credit stored on the SIM card), the maximum number of SMSs that can be sent. The item is
“Remaining” (SMS) in the “General Menu” - “Serial & GSM com.” menu.
If the “General Menu” - “Serial & GSM com.” - “Charge Inf”is set “Active”, every time an SMS
is submitted, the “Remaining” item is updated and will always indicate the remaining number
of messages that the analyzer can send.
With “Chk.Charge” set “Active”, the number of remaining SMS is checked and when is going to reach
zero, a warning SMS containing the text “Maximum number of SMS reached. Please check the cellular
SIM card charge level” is sent.
GSM
This particular situation is managed as an error occurrence and a confirmation of the SMS reception
is waited. After that, a “GSM no credit” warning appears on the display signaling that no other SMS
can be sent.
In this case the user is supposed to extract the SIM card from the cellular module as soon as possible
and check the remaining credit (using its own cellular phone and calling the network operator).
Every time a recharge of the cellular module SIM card is performed, the corresponding expiration
date has to be manually updated – item “Exp.Date” in the “General Menu” - “Serial & GSM com.”.
If the “Chk.Charge” item is set “Active”, a check is performed daily between the current date and the
expiration date. Two weeks before the expiration date, the warning SMS “The cellular SIM card will
expire on: DD-MM-YYYY. Please recharge or substitute it” is sent to the programmed phone number(s).
The same message will be sent again also one week before, and the day before the expiration date.
