Get a device online

To establish network connectivity, turn on your device. Then, you need to make two important configuration changes:

  1. Configure the APN so the device can connect to the emnify network.
  2. Enable roaming.

After that, the device registers to a network (no PIN code entry needed). Once it has registered, your device's Connection changes to Attached. SMS services are now available.

When your device has established a data session, the Connection changes to Online. This means it's ready to send or receive data traffic.


Verify a device's connectivity status in the emnify Portal under Connected Devices.

Configure the APN

Any device equipped with a SIM card requires an Access Point Name (APN) configuration to establish a data session. Some devices and networks auto-detect the APN, but you need to configure it in most cases.

APN: em (or alternatively use emnify)


If your devices have an emnify SIM card, the APN must be em or emnify. No username or password is required.

Further, some Android or iOS-based devices and cellular modules must also be configured to allow roaming.

Common configuration steps often involve:

  • AT commands
    Cellular module settings are done in the device firmware (applies to cellular modules).
  • SMS commands
    Settings are done via SMS (usually for GPS trackers and routers), so you don't need to connect with the device.
  • Device configurator
    Devices must connect through a different interface (serial, USB, Wi-Fi, Bluetooth), and then a graphical configuration user interface guides you through the process.
