Connect to the Internet via cellular

The router can be used to access the Internet through cellular.

There are three cases:

  1. Some models have a built-in 3G/4G model with single SIM card, like GL-XE300(Puli). Please refer to Setup for single SIM models.

  2. Some models have a usb port and can be plugged into a usb 3G/4G modem, like GL-AXT1800(Slate AX). Please refer to Setup for single SIM models.

  3. Some models have a built-in modem and support dual SIM cards, like GL-X3000(Spitz AX). Its interface may be slightly different. Please refer to Setup for Dual-SIM models.

Note: Some SIM cards may need to be activated the first time you use them, so please activate them in your phone before using them in your router.

Setup for single SIM models

The following configuration steps are for built-in modem or external USB modem with only single SIM card. Here we use the GL-AXT1800 (Slate AX) with external USB modem as an example.

On the left side of web Admin Panel -> INTERNET, Cellular sector.

  1. We recommend to turn off the router first, insert your SIM card into the USB modem then plug the USB modem into the USB port of the router, and then turn it on again. If you insert a usb modem at power on, the page may be no change, please refresh the page.

  2. Please access the web Admin Panel -> INTERNET, Cellular sector. The first time, it may not connect automatically, but it has read the name of your carrier in the upper left corner and the IMEI, then please click Auto Setup.

    Please ignore the warning of Incompatible Modem

  3. Connecting.

    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.

  4. After a while, it will be connected. Otherwise, try Manual Setup.

    When the usb modem is plugged into the router the second time it is powered on, it is usually automatically recognized and a connection is established. It may not get the information of signal, modem name and IMEI.

Setup for Dual-SIM models

Some models have a built-in modem and support dual SIM cards, and the interface may be slightly different compare to one SIM card model.

Here take 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, and the user can switch between them.

We recommend to turn off the router first, insert your SIM card into the slot, and then turn it on again.

On the left side of web Admin Panel -> INTERNET, Cellular sector.

If two SIM cards are inserted, you can enable Auto Switch.

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.

  • Auto Switch

    The Internet status is detected in the same way as the settings in the Multi-WAN page.

  • Failover Interval

    If Internet connection is still not available after failover, 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. So that you can switch back to using 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.
