Roaming example
In this example, the desired outcome is to avoid roaming as much as possible, but
if the roaming network is the only one available, to maintain a data connection.
Figure 4-8: ACEmanager: WAN/Cellular > Automatic SIM Switching (Roaming example)
With this configuration:
If the gateway is roaming, for example, on the primary SIM for 10 minutes, it
switches to the secondary SIM.
If the secondary SIM's network is not immediately available, the gateway
continues to attempt to connect for 30 minutes. The gateway switches to the
secondary SIM's network as soon as it becomes available. If, after 30 minutes,
the gateway is still unable to establish a data connection with the secondary SIM,
the gateway switches back to the primary SIM.
If the data connection is lost for more than the configured time (in minutes), the gateway
switches to the inactive SIM card. Options are:
0—The feature is disabled (default)
•
10–255
•
You can also use the *MSNOSERVICETOUT
setting.
Tip: If you prefer to use the Primary SIM account as much as possible, configure the
Secondary Network Timeout (minutes)/(hours)
gateway will periodically check, and switch back to the Primary network when it
becomes available.
If the gateway has been roaming for longer than the time (in minutes) configured in this
field, it automatically switches to the inactive SIM card. Options are:
0—The feature is disabled (default)
•
10–255
•
You can also use the *MSROAMINGTOUT
setting.
This option is useful if the gateway frequently crosses an international border where
there are different Mobile Network Operators in each country. You can set up the
gateway with two SIM cards—one for a Mobile Network Operator in each country. The
gateway then automatically switches to the SIM that is not roaming (after a configured
delay) whenever the gateway crosses the border.
