> [Source Teltonika GPS documentation](https://wiki.teltonika-gps.com/view/Universal_Device_Test_Guide)

### Teltonika Configurator

Teltonika offers the Teltonika Configurator, a graphical user interface, to set device-specific parameters via USB or Bluetooth (for example, the APN and telematics server).
For usage instructions, see [Teltonika's Universal Device Test Guide](https://wiki.teltonika-gps.com/view/Universal_Device_Test_Guide).

### emnify Portal SMS console \[#sms-console-teltonika]

> **Info**
>
> Newer Teltonika GPS versions automatically detect the emnify APN setting.

First, turn on your GPS tracker and ensure the device and emnify SIM card are activated.
If you still need to do this, follow the [Create device](/quickstart/create-device) guide.

Then, follow these steps to set up the APN:

Log in to your [emnify account](https://portal.emnify.com/sign).

Navigate to **Connected Devices** and find your Teltonika GPS tracker.
Turning on the GPS tracker 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.

[Open the SMS console](/portal/sms#open-the-sms-console) and send the command corresponding to your device settings.

If you've set a username and password for the device, use the following SMS command to set the APN:

```txt
USERNAME PASSWORD setparam 2001:em
```

Replace *`USERNAME`* and *`PASSWORD`* with your credentials.

Otherwise, if there's no username or password configured, use the following:

```txt
  setparam 2001:em
```

> **Warning**
>
> The two leading spaces are required.
