DUAL
DATA
SIM
CARD
Some models can have a dual data SIM card: in addition to the internal SIM of the router, it is also
available a specific seat for a second SIM externally accessible.
The internal SIM is the Primary-SIM, while the external SIM is the Secondary-SIM.
Their usage is mutually exclusive and it is controlled by the following rules:
In the default configuration the Primary-SIM (internal SIM) is always used.
By using the commands:
set gprs secondary-sim
set gprs secondary-apn <myapn2>
the external SIM is always used connecting to the APN
myapn2
.
By using the commands:
set gprs primary-sim
set gprs-primary-apn <myapn1>
set gprs secondary-sim
set gprs secondary-apn <myapn2>
The first SIM is used as primary connection to the APN
myapn1
.
If the registration on this APN fails
for 3 times (one after the other), the second SIM may be used on the APN
myapn2
.
