Unlike a consumer device, IoT devices do not automatically configure themselves for connectivity to the network and instead will need to be properly configured.
Your device may have come pre-configured with a consumer APN that will not work with these SIMs. In order to establish a successful data connection when you test your device with the SIM in the kit, please be certain to set your devices APN name to
m2m.com.attz . No user name or password is typically required.
For OneRate SIMs, use m2m64.com.attz .
For NB-IoT OneRate, use APN m2mNB16.com.attz .
This setting can typically be found in your devices connection software or network details. If you are unable to set the APN on your device please contact the device manufacturer for details on how to set an APN on the device.
