I'm trying to decide which to get. Biggest problem/concern:
Do the AT&T LTE hotspots ONLY provide LTE service? Google search only shows them mentioning LTE, not 3G HSPA or 4G HSPA+

EXAMPLE (same pic as in my other thread)

As you can see, in 85+ miles LTE didn't exist. So a large antenna from Onstar wouldn't do anything if LTE is the only option from Onstar, as LTE don't exist in these rural highways.

Can Onstar take the signal from your phone (such as if my iPhone says 3G or 4G HSPA+) and then runs it through the Onstar, using my existing unlimited data plan, therefore still getting the advantage of the large antenna on the car? Or does it not work that way at all?

^^
If the above doesn't work at all, I was thinking about the "weBoost Drive 4G-X for AT&T (470510) "
It says it "Boosts Voice, Text Message, 3G & 4G LTE. Up to +50 dB Gain. Pro Model: 60% More reach from and to cell tower. The weBoost Drive 4G-X has 2x the uplink power compared to the Drive 4G. So that means about 30-60% more reach to the cell tower than your typical car booster. For drivers in extremely rural or poor signal areas, the Drive 4G-X is the first option to look at"

It is $500 bucks though!! So Yeah. If anyone has it let me know how it works in rural areas. A good portion of the drive in the picture above I only had 1 bar of HSPA, which often didn't work for anything. A ghost signal I guess, or just the phone hanging onto a Signal that is so weak it don't work. So even just getting it boosted to say 2 bars of usable HSPA would be a MAJOR improvement for calls/gps/music/emergencies/etc.

Lastly: if the Onstar DOES work to boost 3G/4G HSPA using your existing data plan, and therefore you now have the large antenna on the car for superior signal strength - would that work better than the $500 Wilson Signal booster does? I assume the Onstar antenna is much bigger but Wilson is a dedicated booster so wasn't sure.

Doesn't your GM car include built-in GPS service? No data connection is needed for the car's GPS functionality.

Onstar systems do fall back to At&t or partner 3G or 2G if no LTE is not available. The At&t hotpots also are capable of doing so.

The Onstar system will not run off of your phones data, but you can add it to your existing At&t plan.

Gotcha, good to know it can fall back to 3G/4G if LTE isn't available. But if I'm looking for superior coverage, in rural areas, will the Onstar system provide it due to the large antenna on the car? I am not sure exactly how large the antenna is, but I assume it's like a car's radio antenna? Which is massively bigger then the tiny hidden antenna's they shove into modern smartphones. So the antenna being so large I've heard many reports of improved service/better signal (due to the antenna) some people even get it for that sole reason.
Or is the Wilson Booster that's designed to boost signals a better choice? I am not sure how large the antenna is on the Wilson. I've only had a Wilson cradle booster before, and the mount was tiny. This $500 model one probably is larger, but not sure if the larger antenna you get via the Onstar hotspot is better than the Wilson antenna?
Perhaps someone might know.

I've used the OnStar phone through the catskill mountains in NY, where At&t and Verizon phones had no service. This was last week on a 2017 Silverado.

Good to know. Have you ever had it go to 3G or 4G instead of LTE?
As I know on many highways out here LTE isn't even an option. But a boosted HSPA signal when out rural would still be great.
