There are two ways to communicate to a different backend than to vodafone.
via UDP
NB-IoT devices support primarily only the UDP-protocol. You can not use TCP or higher protocols based on TCP. The backend/cloud, you want to communicate to, must support an UDP-endpoint. You can either change the backend IP via the NB | EASY tool or when you are using the NB | Easy interface.
via Protocol Proxy
There are existing software components, which connect NB-IoT devices to a backend via a proxy, which provides other protocols like HTTP or MQTT. If you are interested in this solution, contact the team of exelonix GmbH.
