GATEWAY TO SMARTER TELECOMS
UNDERSTANDING PORT & SIM POSITIONS
Each of the GSM cards has 4 GSM modules/ports that can each hold up to 4 sim’s giving
you a max of 16 sims per card. Position 1 sim’s for all 4 ports are in the front of the
cards, while positions 2 to 4 are held on the inside of the cards usually hidden inside the
unit.
The picture to the right
illustrates the module and sim
position layouts. These are
important to understand, as a
messy sim deployment can
affect the efficiency of
operation and also slow down
support if required.
INSTALLING SIMS
An important rule of thumb is
to always fill up the sim
position 1’s first before moving
onto positions 2-4 for any
given port/module. This will
ensure the most efficient/even
spread of sims per port.
** Keep it equal, keep it
efficient !!! **
Antenna Connection
With all of the cards fitted with
sims it is now time to connect up the antenna’s. The antennas are mag-mount and
require a metallic surface to sit on for the best performance. Please leave at least 9” of
space between them.
Connect up each antenna to each GSM card.
