I used the KPN LoRa network with a developer account. See the figure below for the logging of the first messages. This prototype is equipped with a RN2483 module of microchip (LoRaBee) in combination with a Teensy 3.1. I did als tested successful an RFM95(W) module in combination with an Arduino-Pro-Mini 3V3.
Due to no antenna of The Things Network near mij home in Doetinchem (The Netherlands), so I could not do any test with this network.
