MiFi vs Jetpack - strictly GB usage question ...

Although we are still under 7 more months of ATT I have both the ATT sierra and Verizon jetpack. The Verizon jetpack seem to be far superior for security than my ATT sierra unit. Never compared it to Melinacom. We try not to do facebook & videos on the road. Although the internet is addictive we like to stick to emails and banking on the road.
