9. Test Signal Strength & Device
Power up the MC3G. The logo LED’s will act
as a signal strength indicator for the Active SIM
once connected. The SIM, 2G/3G, COMMS
and POWER LED’s should turn green once
connected.
SIM LED:
Solid = Using SIM1
Flashing = Using SIM2
2G/3G LED: Solid = 3G Network
Flashing = 2G Network
To check the signal strength
on the Inactive SIM you can
press the ‘Carrier Test’ button
to switch SIM or log into it via
the TechTools app and visit
the ‘Survey’ tab.
If signal strength is less than 2 bars
(>95dB), you must relocate the device or
install a high-gain antenna. If one of the
SIMs cannot meet signal requirements,
the SIM may be disabled
