Another vote for Visible from Verizon at $25 for unlimited LTE data. I moved our Visible phone SIM to a Verizon 7730L Jetpack that doesn't have the 1 user limit that the Visible phones do. We also have a grandfathered AT&T Mobley Connected Car unlimited data plan with the SIM installed in a Netgear Unite Explore hotspot. Everywhere we've been one or the other has worked well and we've never been without service. Our recently installed aimable dual antenna MIMO setup has gotten us even better speeds so far.
