I think something was not understood here.
LoRa is a communitation way. SigFox is a provider that uses another LoPaWan technology. None of them stores anything. In SigFox (which I already use) you need to tell the backend what to do with every message you send to it. In my case I have a callback that forwards the data to Thingspeak, but Sigfox doesn't store or let you visualize your date. The same way your provider's GSM network will let you send the data thru them but you still need an end point where to put the data
What I'm looking for is a cloud service, like ThingSpeak, an alternative.
