When operating on internal antenna, it is recommended to mount GSM-SA away from other electronic
devices. Placing as high as possible will provide a better signal, resulting in more stable communication.

If module is not accessible for any reason, this procedure will reset to default configuration:
- remove SIM card
- connect iw0 and iw1 to C1, leave iw2 and iw3 open
- power on and wait about 15s, until power led shortly goes off
- power off, insert SIM card and continue normal operation
Parameters are now set to default values, allow list is empty (access allowed for everybody).
