ESIM384 Installation and Conguration Manual v1.1
• Via GSM network – Once enabled, the system automatically sends a date/time request to the GSM operator. This method is the
most accurate synchronization method. Some GSM operators might not support it.
• By SMS text message – Once enabled, the system automatically sends the SMS text message to its own phone number and re-
trieves the date and time from the SMS text message reply, as the included date and time is set by the SMSC (SMS center). This
method is not as accurate as the synchronization via GSM network, but always eective.
By default, synchronization via GSM network is disabled. To enable/disable automatic date and time synchronization via GSM network,
please refer to the following conguration methods.
