« Cellular network » parameter :
The router RAS is supposed to connect to the best cellular relay available.
However, in particular situations, it may be useful to force the router RAS to use a particular service.
That parameter gives the choice to select either the LTE 4G service, or the UMTS 3G service or the GPRS-
EDGE service.
The default value is “AUTO”; in that case, the router RAS selects the best available connection.
Cellular IP interface set-up
«Login» & « Password» parameters :

Remark : That parameters are generally not required.
« Obtain an IP address automatically » checkbox :

Using the SIM card
s
1 and 2
Each SIM card can be associated to two different mobiles data services.
In the subsequent text, the cellular service associated to the SIM card 1 is referred to as Network 1 and the
cellular service associated to the SIM card 2 as the Network 2.
The network 1 is first service tested at power-up.
If the Network 1 remains in failure during the period of time T1, the router switches to the network 2.
If the Network 2 is functioning properly, the router uses that cellular network at least during the period of
time T3.
On expiry of that period, the router switches back to the network 1 and checks if it is available. If it is not the
router goes on using the Network 2.
At any time, if the network 2 does not work correctly during the period of time T2, the router switches to
Network 1.
The periods of time T1, T2 and T3 can be selected.
We advise not to select too small values of the T1, T2 and T3 parameters. :
