Does Deutsche Telekom offer both open (public) and closed (private) APNs?
An open (public) APN is currrently offered for testing purposes only. Within a productivity environment only private APNs are currently being offered. Private APNs do either support IP or Non-IP. In case of Non-IP your application data from the device is packed into UDP by the APN and then sent to the user’s backend system (address of backend system is configured on the APN).
We are on T-Mobile Netherlands using UDP. Can we use this open APN? If so, how?
It would make downlinks much easier.
NB-IoT with an IP connection will be available in the summer. But, I will reach out to you next week to learn and find out together how we can make your downlinks easier in the current situation.
