Connect to the Internet via cellular/USB modem¶
Note
This guide is based on firmware v4.8. If you are using old firmware, please visit here.
Some features are only available in v4.8
Most GL.iNet routers support cellular internet access.
There are three scenarios:
-
Some models have a built-in 4G module with a single SIM card slot, such as the GL-XE300 (Puli). Please refer to Setup for Single-SIM models.
-
Some models have a USB port and can be plugged with a USB modem, such as the GL-MT3000 (Beryl AX). Please refer to Setup for Single-SIM models.
-
Some models have a built-in 5G module and support dual SIM cards, such as the GL-X3000 (Spitz AX). Their cellular settings on the web admin panel may be slightly different. Please refer to Setup for Dual-SIM models.
Note: Some SIM cards may require activation upon first use. Please activate the SIM card on your phone before inserting it into the router.
Setup for Single-SIM models¶
The following configuration steps apply to models with a built-in cellular modem and a single SIM card slot (e.g., GL-XE300 Puli), or a USB port for connecting an external USB modem (e.g., GL-MT3000 Beryl AX).
Here we use the GL-MT3000 (Beryl AX) and the external 5G development board GL-M2 as an example. Since the GL-M2 has a built-in module, this connection is implemented through the router's Cellular interface. If using an external USB modem, the connection will instead be implemented through the router's Tethering interface.
We recommend powering off the router first. Plug the USB modem with a pre-installed SIM card into the router's USB port, then power the router back on. If you connect the USB modem after the router has started up, the web admin panel may not update automatically. Please refresh the page to check for changes.
Auto Setup¶
Log in to the router's web Admin Panel, and navigate to INTERNET -> Cellular section.
-
When there's no SIM card inserted, the page displays a message "Your SIM card has not been detected".
-
Insert a SIM card, and it will start connecting, as shown below.
If it does not connect automatically, please click Connect.
Ignore the warning of Incompatible Modem if any.
Note: Some SIM cards may have special usage restrictions, such as the need to use a special APN. If your SIM card cannot be registered, please consult your network operator if it has special restrictions.
-
Once the cellular network is connected, the page will display the network details with a green dot, which indicates a successful connection.
Note: After initial setup, if you restart the router with the USB modem still connected, or re-insert the modem into the router, the USB modem will be automatically recognized, and a network connection will establish without re-clicking "Connect".
If the Auto Setup failed, please try Manual Setup.
Manual Setup¶
Sometimes, Auto Setup may not work, you can try Manual Setup.
In the Cellular section, click SIM Card Settings.
You can view or modify the cellular settings of the current SIM card. It also stores some pre-configured settings, and you can manually add configurations to the "Saved Settings" as well.
Changing the configuration and applying it will result in redialing.
If you want the router block certain bands or only use certain bands, you can enable Band Masking.
Switch the Masking Mode between Block mode and Open mode, then select the LTE bands, 5G NSA Bands and 5G SA Bands.
Compatible Modems¶
Here is a list of supported modems that we had tested before.

Setup for Dual-SIM models¶
Some models have a built-in modem that supports dual SIM cards, and the interface may be slightly different compared to models with only one SIM card.
Taking the GL-X3000 (Spitz AX) as an example. It supports "Dual SIM, Single Standby", which means it can hold two SIM cards for internet access, but only one SIM card can be active at a time. Users can switch between the two SIM cards.
We recommend powering off the router first, inserting your SIM card into the slot, and then powering the router back on.
Auto Setup¶
Log in to the router's web Admin Panel, and navigate to INTERNET -> Cellular section.
-
When there's no SIM card inserted, the page displays a message "Your SIM card has not been detected".
-
When there's a SIM card inserted, the page displays as follows. Click Connect.
-
Once the cellular network is connected, the page will display the network details with a green dot, which indicates a successful connection.
-
Click View More Information to show more cellular information, including the modem details, SIM card details, Internet details, and cellular details.
If the Auto Setup failed, please try Manual Setup.
Manual Setup¶
In the Cellular section, click SIM Card Settings.
You can view or modify the cellular settings of the current SIM card. It also stores some pre-configured settings, and you can manually add configurations to the "Saved Settings" as well.
Changing the configuration will result in redialing.
If you want the router block certain bands or only use certain bands, you can enable Band Masking.
Switch the Masking Mode between Block mode and Open mode, then select the LTE bands, 5G NSA Bands and 5G SA Bands.
Note: Some SIM cards may have special usage restrictions, such as the need to use a special APN. If your SIM card can't be registered, please consult your network operator if it has special restrictions.
SIM Card Slot Settings¶
In the Cellular section, click SIM Card Switch.
You will enter the SIM Card Slot Settings. It displays the auto switch button, the activated SIM card, the ICCID and Network Operator.
If two SIM cards are inserted, you can enable Auto Switch.
-
Auto Switch. It allows auto switch between SIM 1 and SIM 2.
The networking status detection method of SIM card Auto Switch is the same as that configured in the Multi-WAN page.
-
Preferred SIM Card Slot. Set the preferred SIM card as SIM 1 or Sim 2.
-
Failover Interval. The options range from 5 minutes to 24 hours.
If the Internet connection is still not available after failover has occurred, the device will switch back to the preferred SIM slot and will only retry failover after this interval.
This option applies when both the preferred SIM card and the backup SIM card have no signal. If the preferred SIM card also has no signal, the device will switch to the backup SIM card and so on until one of the SIM cards has a signal.
-
Checking Preferred Slot Status Scheduled.
If this option is enabled, the device will try to switch back to the preferred SIM slot at the specified time. This feature allows you to switch back to the preferred SIM slot when its internet connection is available.
When this feature is enabled, the device will attempt to switch to the preferred SIM at this set time each day, for example, this feature is intended to prevent the backup SIM from using too much data, and if the preferred SIM still has no signal, it will fail to switch to the backup SIM.
Note: The Auto Switch feature does not immediately switch to another SIM card. On one hand, it takes time to confirm that the current SIM card cannot access the internet, and only after confirming this will it switch. On the other hand, the other SIM card is not in standby mode, so it also takes some time to activate it.
Traffic Statistics¶
In the Cellular section, click Data Used.
You will enter the Traffic Statistics page. It displays the used data of SIM card(s), and provides data limit settings.
If the Data Used exceeds the Data Cap Amount, please modify the Data Cap Amount or the Data Used manually. Otherwise, the network may be disconnected, or the SIM card may Auto Switch (for Dual-SIM models).
-
Modify the Data Used
Click on Modify on the right side of SIM 1/2 Data Used.
Then you can modify or reset the data used.
-
Set up SIM data limit
If you want to set up the SIM data limit, enable Save data when power off first. It means the data can be saved even after the device is powered off.
Then enable the SIM 1 or SIM 2 Limit Settings.
For Dual-SIM models, we suggest enabling the SIM Card Slot Auto Switch at the same time. If the SIM 1 Data Cap Amount is set and the SIM Card Slot Auto Switch is enabled, SIM 1 will automatically switch to SIM 2 when it's data exceeds the Data Cap Amount and SIM 1 will be disabled.
Historical Signal Record¶
In the Cellular section, click Historical Signal Record.
Checking your router's signal strength can help you determine the quality of your Internet connection. If the quality of your internet connection is poor, you can try switching to get a better signal.
You can view the Cellular signal strength history by selecting different time frames in the upper right.
SMS¶
Please refer to the SMS tutorial.
SMS Forwarding¶
Please refer to the SMS Forwarding tutorial.
Lock Tower¶
This feature is only supported by GL-X3000, GL-XE3000, and GL-X2000 (firmware ver.4.7).
If you want to receive high-quality signal sources to ensure stable cellular connection, you can try locking tower.
Note: Locking onto a base station requires matching the carrier and the device's supported frequency bands; otherwise, it may affect dialing. Please confirm the base station information to avoid potential issues.
In the Cellular section, click the three-dot icon in the upper right, then select Lock Tower.
Click Scan to start scanning the cellular towers or the base stations. It will take about a few minutes to scan the tower.
When scanning, do NOT refresh the page.
It will display the available towers.
Click a tower to view the details and lock onto it.
Please note that if the locked tower does not match the band masking or APN parameters in the cellular settings, the cellular interface will not be able to connect to the Internet.
After locking a signal tower, if the router is moved to another location, it will still attempt to reconnect to the locked tower after booting up. This may consequently prevent the router from connecting to the cellular network automatically at the new location. In this case, you need to either unlock the current signal tower via the router's web admin panel, or manually lock it to a new tower.
Lock Operator¶
This feature is only supported by GL-X3000, GL-XE3000, and GL-X2000 (firmware ver.4.8).
If you want to lock onto specific operator, in the Cellular section, click the three-dot icon in the upper right, then select Lock Operator.
The operator lock function supports three modes:
- Auto. Automatically connect to an available operator network.
- Manual. Manually lock onto a specific operator.
- Manual-Auto. Automatically switch to an available operator network if the manual lock fails.
Modem AT Command¶
In the Cellular section, click the three-dot icon in the upper right, then select Modem AT Command.
You will enter the AT Command page.
Modem AT commands are instructions that are used to control modems.
When the 'Shortcut' option is selected as 'Manual command', you can enter the command to be executed in the 'AT Command' field.
You can also click the 'Shortcut' to switch to other preset commands.
The following AT Commands have been pre-set.
- Request IMEI
