but can you please recommend a really good tutorial for a dongle with GPS capabilities and extracting RTC time?
I will be in the Netherlands, so Dutch providers. I only need to send to the cloud a tiny CSV file every x seconds.

If you go for the latter have a look at MQTT for passing the data. You may have to encode it if binary or use the file option) but a lot of the transfer code and reliability is ready built for you. It supports a quality of service mode (QoS 3) that delivers the data once and only once if you have not seen this have a look at https://thenewstack.io/mqtt-protocol-iot/
