3. Preparing and Inserting the SIM Card into the Module
To ensure the proper functioning, it is necessary to perform the following steps before inserting
the SIM card into the module.
1. If the SIM card is not activated, activate it in the mobile phone according to the SIM card
manual.
2. Disable the voice mail. Refer to instructions of the selected GSM operator or call its hotline.
3. Disable the use of the PIN code according to the mobile phone manual.
4. Delete all saved contacts and SMSs from the SIM card.
5. When using the USBCommunicator utility, you need to insert the SIM card without phone
numbers of authorized users. If the computer is not available, the phone numbers of the
authorized users must be stored in the SIM card. Any mobile phone can be used for this.
With the power supply off, insert the prepared SIM card into the G2S-T module. The card
insertion method is shown on the side of the module. The card should be pushed in until it clicks
and remains in the slot. To remove the SIM card, push it again to release it and then pull it out of
the module.
4. Setting the Authorized Phone Numbers Using the SIM Card
Without using the USBCommunicator utility, you can enter up to ten phone numbers using a
mobile phone. The numbers must be stored on the SIM card in the international format,
including the leading characters + or 00 (e.g. +420123456789). Users' names must be USER0,
USER1, ..., to USER9. After inserting the SIM card into the G2S-T module and turning the
module on, the stored phone numbers are transferred from the SIM card to the internal memory
of the module. The numbers are transferred from the SIM card to positions 0 to 9 of the
G2S-T module every time it is switched on. This will overwrite the corresponding number
of internal module memory positions according to the number of users stored in the SIM
card!
5. Setting the Module Using the USBCommunicator Utility
For a more convenient setting of the G2S-T module, you can use the supplied
USBCommunicator software. To avoid overwriting of the stored phone numbers when the
module is turned on, no phone numbers can be stored in the inserted SIM card,
otherwise changes in the first 10 positions made using the utility may be overwritten by
numbers from the SIM card when the module is turned on. When preparing the SIM card
according to Chapter 3, it is necessary to perform only steps 1 to 4 and insert the SIM card
without stored phone numbers into the module.
