GSM geolocation
GSM geolocation is a way to determine the position without the use of GPS. Only information from
the mobile network is used. The information is sent to a third-party operator that returns the
coordinates of the device with some accuracy.
The positioning is more inaccurate compared to GPS, but it also works indoors. It is especially
suitable for tracking parcels, refrigerated display cases, refrigerators, machines and equipment
operating where there is no GPS signal.
TCG120-4 supports the following operators - Google, Quectel, and Unwired Labs. The service needs
registration with the operator.

Backup/Restore
TCG120-4 supports backup and restore of all user settings. All settings are saved in an XML backup file.
This file can be used after this to restore the same settings on many devices. This is very useful for
multiplying similar settings to a batch of modules.
