multiple slots are provided, the upper slot will be labeled SIM-B and the lower slot will be
labeled SIM-A.
NOTE The sim-slot option will not be visible unless Dual SIM functionality is installed in the factory
as part of the selective order-entry feature, for the 3G module. By default units are shipped with
only SIM-A enabled; SIM-B is not supported.
In addition to the Connection Profile configuration, the Connection Profile Switching feature allows a
user to enable switching when one or more profiles are configured on a unit. This feature can be used to
implement dual SIM functionality, where the user obtains and configures a unit with two SIM cards, each
from a different cellular provider. This can help increase the reliability of the connection by allowing the
unit to switch to a different SIM card if data connection with the other SIM card fails for any reason (for
example, due to reduced signal strength and so on).
For example, the UI screen for a Connection Profile Switching is shown below:
Interfaces / Cell ---> Basic Config / Cellular
Figure 3-25. Connection Profile Switching Example
 Switch to Next on Roaming - This parameter enables connection profile switching when the
roaming-state of current connection changes to roaming. DEFAULT - FALSE (disabled).
 Switch to Next on Failure - This parameter enables connection profile switching when data
connection failure occurs when using the current profile. DEFAULT - FALSE (disabled).
 Switch to Next on Failure Timeout - This parameter specifies the time interval for which
data connection is attempted using the current connection profile before switching to next one
in the list. DEFAULT - 30 min.
 Switch to First on Timeout - This parameter enables switching of connection profile to the
first one in the list irrespective of current connection status. DEFAULT - FALSE (disabled).
 Switch to First Timeout - This parameter specifies the time interval after which data
connection is attempted using the first profile in the list regardless of current connection status.
DEFAULT - 60 min.
NOTE The cellular provider network can disconnect the cellular connection if any packets get routed
from LAN to Cellular interface without undergoing masquerading (Source Network Address
Translation (NAT) before exiting the cellular interface. Therefore, always configure
masquerading on the cellular interface. See “Source NAT (Masquerading)” on Page 226 for
more information on NAT configuration.
Use of the “Connection Profile Switching” feature requires the user to configure two profiles; each with
specific cellular provider information for the respective SIM slot. For example, say the SIM card from
carrier A is inserted in SIM-A and the SIM card from carrier B is inserted in SIM-B.
 Configure a profile for carrier A to use SIM-A:
% set interfaces interface Cell cell-config connection-profile CARRIER_A bearer-config apn
carrierA.apn
% set interfaces interface Cell cell-config connection-profile CARRIER_A sim-slot SIM-A
 Configure a profile for carrier B to use SIM-B:
