Remarks Description
The Smart Dongle
has no SIM card or
the SIM card is in
poor contact. Check
whether the SIM card
has been installed or
is in good contact. If
not, install the SIM
card or remove and
insert the SIM card.
The Smart Dongle
fails to be connected
to a management
system because the
SIM card has no
signals, weak signal
strength, or no traffic.
If the Smart Dongle
is reliably connected,
check the SIM card
signal through the
SUN2000 app. If no
signal is received or
the signal strength is
weak, contact the
carrier. Check
whether the tariff
and traffic of the SIM
card are normal. If
not, recharge the SIM
card or buy traffic.
