To avoid such problems it is recommended (and is good practice) to locate the power supply as
close to the device as possible. This avoids power cable noise and interference and enhances the
lifetime of the product.
Inserting the SIM card
Note: This unit is a dual 3G/4G system, operating on either 3G or 4G network frequencies.
Connections on the GSM Controller
Please ensure the SIM card is a 3G/4G compatible Nano SIM card.
The SIM may also be 2G capable as well, as long as both the SIM
and the network also support 3G/4G. Do not use a SIM card for a
tablet, as these only support data, and do not support voice and
SMS. You simply require a mobile phone type SIM card.
