Is it possible to buy a SimpleHw GPS, LoRa or NB-IoT tracker?
No... And we will no be producing any GPS, LoRa or NB-IoT devices anytime soon. Our devices are based on Sigfox. Our devices cover use cases that we think are best covered by the Sigfox technology. If you're interested in more information, here's our take on the differences of the three IoT technologies: https://ask.simplehw.eu/sigfox-lora-nbiot
And for GPS - GPS module require a lot of battery to operate, our devices are designed so they last years/tens of years, which would simply not be possible with GPS.
And we've written a blog post on the topic a while back as well: https://simplehw.eu/simple-hardware-and-semtech-lora-and-nb-iot/
All our devices can be found on the eshop here: https://shop.simplehw.eu
