We had/have an ATT hotspot for the last year or so. Camping often in Missouri and at a couple of our favorite parks never a problem, last year. Early this spring as we set up camp and got no signal we learned that ATT pulled their tower/service to that area. DW went insane with no FaceBook so we're off to Wally World and got a Verizon. Ta Da! the world is at peace again and FaceBook is restored. Finished our stay and headed to our next MO State Park. Guess what doesn't work there? Yup the Verizon. Had time left on the ATT so fired that up. Now we carry two hotspots. Thank goodness 2gb will last us about 2 weeks of more, because we do no streaming. But still a royal pain figuring which to activate or just bite the bullet and do both. Only saving grace is that we rarely travel for more than 2-3 weeks at a time.
