2. Insert the SIM card into the socket
For security reasons use SIM card with private IP address. Using
SIM card with public IP address makes the device visible on the
internet, exposing it to much higher security risk.
Mobile connectivity of the device can be ensured by using a
proper SIM card:
• There must be a mobile internet subscription associated
with the SIM card.
• SIM card must be activated by the mobile operator.
• Use 2FF mini SIM card size.
• SIM card must be inserted with the proper direction.
(as seen on the picture below)
• PIN code must be disabled.
• For security reasons use SIM card with private IP address.
• The selected provider must not have APN username and
password.
• APN setting of the device must set to the value got from the
mobile operator to the SIM card.
