The information in this page is updated in accordance with firmware version TRB2_R_00.07.02.4.
The Mobile page is used to configure mobile connection settings.
This manual page provides an overview of the Mobile page in TRB245 devices.
If you're having trouble finding this page or some of the parameters described here on your device's WebUI, you should turn on "Advanced WebUI" mode. You can do that by clicking the "Basic" button under "Mode", which is located at the top-right corner of the WebUI.
The General section is used to configure SIM card parameters that define how the device will establish a mobile connection.
SIM card settings
The SIM Card Settings section is used to configure main SIM card parameters. Refer to the figure and table below for information on the fields contained in that section.
|Default SIM||off | on; default: on||Sets this SIM slot as the default one.|
|Deny data roaming||off | on; default: off||Denies data connection on roaming conditions.|
|VoLTE||Auto | On | Off; default: Auto||Enables Voice over LTE, a digital packet technology that uses 4G LTE networks to route voice traffic and transmit data.|
|Service mode||Auto | 4G (LTE) only | 3G only | 2G only; default: Auto||Network connection type preference.|
|PIN||integer [0000..99999999]; default: none||SIM card's PIN (Personal Identification Number) is a secret numeric password used to authenticate the device to the SIM card. PIN codes are comprised of numbers only and the length can range from 4 to 8 symbols. PIN number is saved in flash memory therefore it does not reset when default settings are restored.|
The Operator Settings section is used to configure which operators can be allowed (Whitelist) or blocked (Blacklist) for specified SIM card.
|Enable||off | on; default: off||Enables Whitelist or Blacklist for specified operator list.|
|Mode||Whitelist | Blacklist; default: Whitelist||Mode to be applied for operator list.
|Operator list||operator list; default: none||A list of operators which can be configured in Operators List page.|
SMS limit settings
The SMS Limit Settings section provides you with the possibility to set up a maximum sent SMS message cap for your SIM card.
|Enable SMS Limit||off | on; default: off||Turns SMS limiting on or off.|
|SMS limit count||integer; default: none||Sets the SMS sending cap, i.e., how many SMS messages can be sent from this SIM card during the specified period.|
|Period||Day | Week | Month; default: Day||Period for which SMS limiting should apply. After the period expires, the SMS limit counter will be reset.|
|Start hour/day||0-23 / Monday - Sunday / 0-31; default: 0||Starting hour of the day / day of the week / day of the month for SMS limiting period.|
|Clear SMS Limit||- (interactive button)||Clears the SMS limit counter for the selected period.|
Unstructured Supplementary Service Data (USSD) is communication protocol used in communication between cellular devices and mobile network operators. It is usually used with prepaid SIM cards to enable/disable certain services or to obtain information from a network operator.
This section provides the possibility to send USSD messages to the mobile operator.
|USSD||string; default: none||Enter a USSD code (up to 182 character) that you wish to send. To send the entered USSD code, click the 'Send' button below the Response box.|
|Response message||string; default: No response yet||Displays the response to the last sent USSD message. Receiving the response may take up to a minute.|
|Send||- (interactive button)||Click to send the message entered in the USSD field.|
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.
|Enable automatic switching||off | on; default: off||Turns automatic SIM switching on or off.|
|Check interval||integer [3..3600]; default: 10||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.|
|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:
When configuring SIM switching from the Secondary card, an additional field called "Switch back to primary SIM card after timeout" becomes available:
|Switch back to primary SIM card after timeout||yes | no; default: no||Attempts to switch back to the primary SIM card once the specified period of time passed.|
|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.|
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.
|Active SIM||SIM 1 | SIM 2; default: SIM 1||Displays which SIM card is currently active.|
|Current operator||string; default: none||Displays the name of the operator the which the device is currently connected.|
|Connection mode||Auto | Manual | Manual-Auto; default: Auto||Operator selection method.
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 'Operators List'.
In order to lock the SIM card to using a single operator, place a check mark next to the relevant entry in the list and click 'Save & Apply'.
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).
