We use Verizon for smartphones and data. Until last month we used their jetpack and it worked fine from Maine to Florida. We don't watch TV or movies so 4 GB worked fine. Recently we went in to Verizon and found out we could lower our bill if we used a their tablet as a hot spot so we now have a tablet which I use more than my laptop and our bill also dropped and we now have 10 GB. Verizon has always been very reliable for us.
