Configure the APN on industrial routers

Teltonika Networks​

Applies to RUT240, RUT950, RUT955, RUTX09, RUTX11, RUTX12, RUTX14, RUTXR1, RUT360

Newer firmware versions of the Teltonika Networks' industrial cellular routers should automatically detect the emnify APN. If the APN isn't correctly detected, you can configure it in three ways:

Teltonika WebUI​

  1. Connect your PC through the router's Wi-Fi using the credentials provided on the device.
  2. Open the Teltonika WebUI http://192.168.1.1 and go to the Mobile Configuration.
  3. Type in em in APN. Make sure to select the Auto checkbox.
note

There's no PIN number configured on the SIM.

emnify Portal SMS console​

First, turn on your router and ensure the device and emnify SIM card are activated. If you still need to do this, follow the Create device guide.

Then, follow these steps to set up the APN:

  1. Log in to your emnify account.
  2. Navigate to Connected Devices and find your Teltonika Networks router. Turning on the router for the first time after installing the SIM shows the status as Attached. The device can receive SMS at this point but only establish a data session if the APN is set up or detected.
  3. Open the SMS console and send the following command:
cellular apn=em
info

See Teltonika's SMS Commands reference for a comprehensive list of SMS commands, syntax, and usage.

emnify REST API​

You can use the SMS calls in the emnify REST API to automate the device configuration.

tip

Follow the Getting started guide in the emnify System Documentation to learn how to authenticate and use the API.

To send SMS to a device, use POST /api/v1/endpoint/{endpoint_id}/sms with the following request body:

{ 
  "source_address": "123456789",
  "payload": "cellular apn=em" 
}

Replace 123456789 with your chosen source address.
