Ok, some news: If I publish something to any of my topics with QoS set to 1, I can receive the message from the topic I subsrcibed to, but, unfortunately, only one time. The callback function runs fine, but then, the main loop is blocked. I can see, that the sensor threads are still running fine, but there are no more data published, because of the blocked main loop. Cheers, Thomas

@trojanc Well, i have a talk with a sigfox founder. First news about this topics is Sigfox France Network now sell device subscription by year for one device. Unfortunatly this will not help you in this case, sorry. It seem that kenya and south africa is not still available on buy.sigfox.com, as all technical event is off i dont know where i can see someone from sigfox in futur to ask us some news.
