Programming the GSM Intercom
1111BAL?
Check current balance of the SIM in the GSM intercom and send a confirmation text back
to the sender.
In addition to this feature the GSM intercom also has the facility to monitor the available credit and then text the user to inform

the credit has either increased or if it runs out.

1. A Pay As You Go SIM card from a provider that offers this service (Vodafone, O2) must be used.
2. The correct balance check string must be stored using the
SDL
code (see store balance check dial string on page 42).

using the
STM
code (refer to ‘store master telephone number’ feature below).
