We use 4G LTE networks to provide internet access. There are 3 service plans offered: UnlimitedToGo Blue, UnlimitedToGo Pink, and UnlimitedToGo Red. The difference between the plans is just the 4G LTE network that each plan operates on. All of the plans provide unlimited data without overages, high speed data caps, or usage based throttling. And because the service is provided through wireless 4G LTE networks, you can use the service at home or on the go. All you need is one of the hotspots/routers that are offered along with their corresponding plan.
