Best decision i've ever made was buying a vehicle with built in wifi.
GM's Onstar data plan is $20 and does not require onstar activation. It's unlimited (Throttled at 22 Gb, but if you do go that high the limitations will be signal strength and data speeds out on the plains)
Unfortunately, it's AT&T based. However, because of the car's (Silverado) signal strength finding (truly) dead zones are surprisingly pretty rare. Tested in eastern South Dakota, Several remote areas of Iowa, Central Nebraska and Kansas, and east of OKC. I've found exactly one remote intersection in central South Dakota where data was really poor.
Even when signal is suboptimal, I can listen to podcasts and when I'm not driving I'm watching youtube videos. On vacations, sometimes 3 different people might be streaming video/podcasts in my truck at the same time without interruption. This is soo much better than my experience with boosters and jetpacks.
All i need are some good storms to test out performance while live streaming.
