So was wanting to try and switch my house to a 4G setup over my current Comcast. However looking to clarify a couple of things. Sure I have a TB and love tether with my devices, but for the day to day I would want the hotspot to keep the signal all the time whenI am not there for the wife and kids. But with the hotspot I know that they have a cap on the pricing. So then comes how much data do I use through my house. Here is my issue. Is the data used through the cable modem equal to the data that would be used over 4G. What I mean is I am using about 115GB a month on my cable modem. So ... to go 4G.. would cost way more?? Yes? Am I missing something?
