RAK5860 for MQTT/Internet connectivity?

I’m wondering if the RAK5860 NB-IoT module on a wisblock with a RAK4630 is something to go for in terms of linking out the LoRa signal from a remote location to the internet/ MQTT and if there may be support for this in the future?
I very much like the RAK hardware, quality wise it’s very good and small form factor. I’m also very surprised at how low power these things are. I have had two 4630’s running for weeks now in router mode in the tiny solar panel enclosure they sell. At my northern latitude the sun is up almost permanently now but nevertheless it’s impressive that they can run permanently off of such a small panel, they’re just on a 2650 mAh battery each.
