For NB-IoT we have an UDP adapter. So with NB-IoT you’ll need to use APN cdp.iot.t-mobile.nl which will allow you to send device data to 172.27.131.100.

To retrieve the device data in your back-end/cloud server/iot platform, you’ll need to create an HTTP integration.

If you use the sim-card for LTE-M or 2G, you’ll need another APN: m2m.public.nl. By doing this, the device will get a public IP address just like any other device on the open internet. This means that you can send device data directly to your own server while using LTE-M or 2G.

Hope this helps!
