SMS Limit

The SMS Limit page provides you with the possibility to set up a limit of SMS messages that each of the router's SIM cards can send in period of one day, week or a month.

SMS Limit Configuration

---

The SMS Limit Configuration section is used to configure custom SMS limits for your SIM card(s). In order to limit sent SMS messages, select the SIM card (SIM1 or SIM2), enable SMS limit and configure the limit conditions. For related information, refer to the figure and table below.

Field	Value	Description
Enable SMS limit	yes | no; default: no	Turns SMS limitations on or off.
Period	Month | Week | Day; default: Month	SMS limit period after which the sent SMS counter is reset on the specified Start day.
Start day | Start hour	day of the month [1..31] | day of the week [Monday..Sunday] | hour of the day [1..24]; default: 1	Specifies when the period of counting SMS messages should begin. After the period is over, the limit ir reset and the count begins over again.
SMS limit*	integer; default: none	Number of SMS messages that the is allowed to be sent over the specified period of time. When the limit is reached, the router will no longer be able to send SMS messages until the period is over or SMS limit is reset. Note: after the router has reached the SMS limit it will not switch to using the secondary SIM card. If you wish to configure a SIM switch system based on sent SMS limit, instructions can be found in the SIM Switching rules section of this page.

* Your carrier's SMS usage accounting may differ. Teltonika is not liable should any accounting discrepancies occur.

Clear SMS Limit

---

The Clear SMS Limit section displays the ammount of sent SMS messages and provides the possibility to reset that counter. When the 'Clear SMS button' is clicked, it clears the SMS limit counter for the related SIM card. Thus, the count is started over again regardless of the specified period.

Important: remember that the 'Clear SMS limit' button doesn't clear the actual sent SMS statistics for the SIM card, only the SMS counters as calculated by the router.

SIM Idle Protection

Some operators block user SIM cards after a period of inactivity. The SIM Idle Protection window 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.

Settings

---

The Settings tab is used to configure the parameters used by the SIM Idle Protection function.

Field	Value	Description
Enable	yes | no; default: no	Toggless SIM Idle Protection ON or OFF
Period	Month | Week; default: Month	Period after which a SIM switch will occur
Day	day [1..31] | day [Monday..Sunday]; default: day 1	Day of the month or week when the SIM switch will occur
Hour	hour [1..24]; default: 1	Hour of the day when the SIM switch will occur
Minute	minute [0..59]; default: 1	Minute of the hour when the SIM switch will occur
Host to ping	ip; default: 127.0.0.1	When the SIM switch occurs, the router will ping a host specified in this field
Ping package size	integer [1..100]; default: 56	Size (in bytes) of the package that will be sent
Ping requests	integer [1..30]; default: 2	How many ping packets will be sent

Test

---

Once you have configured your SIM Idle Protection settings, the Test tab will provide you with possibility to test these settings to make sure everything works correctly. Once you click the Test* button, the test will initiate. The test is designed to simulate SIM Idle Protection according to your current SIM Idle Protection settings.

The test takes about 2 minutes, so make sure the router isn't doing anything important before you start the test because during it you will lose connectivity. Once you have started the test you will see this warning appear:

It is very important to heed this advice since if you commit any action during test phase (apply new configurations, reboot the router, etc.) you may cause the router to crash, which could require a Factory Reset to fix

---

Above is an example of a successful Test. The test results display both SIM cards' IMSI (International Mobile Subscriber Identity), ICCID (Integrated Circuit Card Identifier), host to ping, WAN IP and whether the ping was successful or not.

USB Modem

The USB Modem section is used to configuration the connection settings of a USB modem attached to the router's USB connector. This section only becomes visible when a USB modem is connected to the router.

The configuration is a minimalistic version of the regular SIM card settings page:

Field	Value	Description
APN	string; default: none	An Access Point Name (APN) is a gateway between a GSM, GPRS, 3G or 4G mobile network and another computer network. Depending on the contract, some operators may require to enter the APN just to complete the registration to a network. In other cases, APN is used to get special parameters from the operator (e.g., a public IP address) depending on the contract. NOTE: an APN Network Identifier cannot start with any of the following strings: "rac", "lac", "sgsn" or "rnc"; it cannot end in ".gprs" and it cannot take the value "*"
PIN number	string; Default: none	A personal identification number (PIN) is a numeric password used to authenticate a user to a system (in this case, the user to the SIM card)
Authentication method	CHAP | PAP | None; Default: None	The Authentication method that your GSM carrier uses to authenticate new connections on its network
Username	string; Default: none	The username used to connect to your carrier’s network. This field becomes available when you select an Auth Mode (i.e., the selected Auth Mode is not “None”)
Password	string; Default: none	The password used to connect to your carrier’s network
Service mode	2G only | 3G only | 4G (LTE) only | Automatic; Default: Automatic	Your service mode preference. If your local mobile network supports 2G, 3G and 4G (LTE) you can specify to which type of network you wish to connect to, e.g., if you choose 2G only, the router will connect to a 2G network, so long as it is available, otherwise it will connect to a network that provides better connectivity. If you select Automatic, then the router will connect to the network that provides the best connectivity

To select the USB modem to act as a WAN connection, go to the Network → WAN page.
