1.10.6. Switch between SIM cards configuration
You may define rules in the router for switching between two APNs on one SIM card
or between two SIM cards, if two SIM cards are inserted. The router can automatically switch
between the SIM cards if the active PPP connection is lost, the data limit is exceeded, or the
binary input on the front panel goes active.
Item
Description
Default SIM card
This parameter sets the default APN or SIM card for the PPP
connection. If this parameter is set to none, the router boots up in off-
line mode and it will be necessary to initiate the PPP connection by
sending an SMS message to the router.
Backup SIM card
Defines the backup APN or SIM card.
Table 17: Default and backup SIM configuration
If parameter Backup SIM card is set to none, then the parameters Switch to other
SIM card when connection fails, Switch to backup SIM card when roaming is detected
and Switch to backup SIM card when data limit is exceeded will switch the router to off-
line mode.
Item
Description
Switch to other SIM
card when
connection fails
If the PPP connection fails, the router will switch to the secondary
SIM card or secondary APN of the SIM card. The router will switch to
the backup SIM card if the router is unable to establish a PPP
connection after 3 attempts or the Check the PPP connection option
is selected and the router detects that the PPP connection has failed.
Switch to backup
SIM card when
roaming is detected
If roaming is detected, this option forces the router to switch to the
secondary SIM card or secondary APN of the SIM card.
Switch to backup
SIM card when data
limit is exceeded
This option enables the router to switch to the secondary SIM card or
secondary APN of the SIM card when the data limit of default APN is
exceeded.
Switch to backup
SIM card when
binary input is active
This parameter forces the router to switch to the secondary SIM card
or secondary APN of the SIM card
when binary input „bin0‟ is active.
Switch to primary
SIM card after
timeout
This parameter defines the method the router will use to try to switch
back to the default SIM card or default APN.
