LTE Connectivity (in the 945)

With Garmin releasing a 945 LTE, I was wondering, how does connectivity impact widgets?

Will the widgets have full internet access while on LTE? For example I have a SmartThings app which allows me to open my garage door, could this be used on the LTE?

I'm just wondering what are the use cases there, could a developer build a messaging app on Garmin? Even something like:

Garmin Watch LTE -> Cloud -> Phone -> Send text message

Or is this just an LTE available to the Garmin software?
