Field Value Description
PIN 4-8 positive numeric chars (positive number); default: none SIM card's PIN (Personal Identification Number) is a secret numeric password shared between a user and a system that can be used to authenticate the user. PIN is saved in flash memory, it will be saved after device reset.
PUK 8 positive numeric chars (positive number); default: none SIM PUK (Personal Unblocking Key) is a code consisting of 8 digits. It is used to unblock your SIM card when you entered 3 times a wrong PIN code

SIM Switch

The SIM Switch section provides you with the possibility to configure SIM switching rules, i.e., set up circumstances under which the device will perform a switch from using one SIM card to another. Refer to the figure and table below for information.

Networking rutos manual mobile sim switch v1.png

Field Value Description
Enable automatic switching off | on; default: off Turns automatic SIM switching on or off.
Check interval integer [3..3600]; default: 30 The frequency (in seconds) at which the device will check for SIM switch conditions. If such a condition exists, the router will perform a SIM switch, if not - it will check for the same conditions again after the amount of time specified in this field passes.
Attempts before SIM switch integer [1..10]; default: 3 How many times a condition will be checked before executing a SIM switch. For example, if the device is a state that meets at least one SIM switch condition, the device will perform a number of additional checks specified in this field and will perform a SIM switch only if the condition is met on every check.
On weak signal* off | on; default: off Performs a SIM switch when the signal strength drops below a certain threshold.
*Signal strength (dBm) integer [-120..-50]; default: -90 Lowest signal's strength value (RSSI) in dBm below which a SIM card switch should occur. More information: RSSI
On data limit off | on; default: off Performs a SIM switch when the mobile data limit for this SIM card is reached. You can set up a mobile data limit in the Network → WAN (Basic WebUI mode) or Network → Interfaces (Advanced WebUI mode) pages by clicking 'Edit' next to the interface you wish limit the data for.
On SMS limit off | on; default: off Performs a SIM switch when the SMS limit for this SIM card is reached. You can set up SMS limit in the Network → Mobile → General page.
On roaming off | on; default: off Performs a SIM switch when roaming conditions are detected.
No network off | on; default: off Performs a SIM switch when a network connection is not available.
On network denied off | on; default: off Performs a SIM switch when access to a network is denied by an operator.
On data connection fail off | on; default: off Performs a SIM switch when mobile data connection fails. Possible failure determination methods are:
  • LCP echo
  • ICMP echo
If no echo is received, the data connection is considered to be down.

When configuring SIM switching from the Secondary card, an additional field called "Switch back to primary SIM card after timeout" becomes available:

Initial timeout (min) integer; default: 1 Indicates a time value (in minutes) after which the device will attempt to switch back to the primary SIM card.


APN Database

APN stands for Access Point Name and allows a device's network to connect to the internet. With the APN settings in place, your device builds a connection to a carrier's gateway. APN Database page section provides you with possibility to create/edit/delete APN records. Note: APN Database is additional software that can be installed from the System → Package Manager page.
