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.

Network operators

The Network operators section provides you with the possibility to scan for and manage mobile network operators to which the device's SIM card can connect to. Operator selection is only available for the primary SIM card. In order to specify an operator for the other SIM card it must first be selected as the Primary SIM in the SIM card settings section.

Field	Value	Description

(More on this selection below.) Manual-Auto - prompts you to enter an operator's code, but if the router can't complete the connection, it will automatically connect to the next available operator.

Manual operator selection

---

To select an operator manually, specify Connection mode: Manual and click 'Scan For Operators'.

Will be prompted with a pop-up asking if you're sure. Click 'Scan' if you wish to proceed.

Wait for the scan to finish. As indicated by the onscreen message, the process can take up to 3 minutes.

---

Once the scan has finished, you will see the results in the 'Available operators'.

In order to lock the SIM card to using a single operator, select operator from Operator code field and click 'Save & Apply'.

Operators list

---

This section is used to create lists of operators codes, which can then be used in Operator settings section to Whitelist of Blacklist them. Operator code consists of two parts - Mobile Country Code (MCC) and Mobile Network Code (MNC).

By clicking Edit on a list you will be redirected to editing page in which you can enter operator codes for that list.

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.

Adding new APN

---

In order to create new APN to database, insert required information and click Add button.

SIM Idle Protection

Some operators block user SIM cards after a period of inactivity. The SIM Idle Protection tab provides you with the possibility to configure the router to periodically switch to the secondary SIM card and establish a data connection with a mobile network operator in order to break the idleness and prevent the SIM card from being blocked.
