This article contains instructions on how to use the device's Multi-APN feature to connect to multiple mobile networks using a single SIM card. This feature can also be called “Multiple PDN”.
Requirements;
Latest firmware with multi-APN support (R_00.07.00 and newer)
SIM card with multiple APNs.
If you are having trouble finding some of the parameters described here in your device's WebUI, you should turn on the “Advanced WebUI” mode. You can do this by clicking the “Basic” button under “Mode” located in the upper right corner of the WebUI.
1-Create a new mobile interface.
Connect to the router's WebUI, go to Network > Interfaces. Find the Add New Instance section below, enter a name for your mobile interface, and click ADD.
2-Configure the new interface.
After adding a new interface, the interface configuration window should appear. In the protocol list, select Mobile.
Then configure the interface in this order:
1. Disable automatic APN.
2.Select an APN from the list or select — Custom — to define a custom APN.
3. Enter your APN in the Custom APN field.
4.Click Save and Apply below.
The new interface should appear in the list and start connecting to mobile data.
Once connected, you will see an IP assigned based on the APN.
If your new interface cannot connect, make sure you do not set the same APN on the default mobile interface for that SIM card.
3-Configure the default interface.
After pressing EDIT, the interface configuration window should appear. Follow the same steps in 2. with a different APN, or leave it on Auto APN if the interface automatically connects to a different APN.
The default interface should soon connect to the data with an IP assigned according to the APN;
You should see two different mobile interfaces connected to the data with different IPs assigned;
You can also check if the configuration was successful by pinging an address accessible from the internet via CLI or SSH:
To ping from the default interface, use the following command;
ping -I qmimux0 8.8.8.8
Use the following command to ping from the created interface;
ping -I qmimux 8 8.8.8.8
