Xfinity Essentials

Greetings

I had Comcast Cable/Xfinity basic plan for years but am on a limited fixed income so I had to make the choice to end that. My internet was provided by another company and was getting to the point where I would have to decide if I could do without it. I was told about Xfinity Essentials awhile back maybe over a year and called and they now provide in NJ.

So I cut the cable cord and closed the internet account and got the Essentials. I know you received 1 terabyte (1,024 GB) per month. When I applied for the plan I knew that would meet my needs then I decided to purchased FireTV from Amazon. Never thinking that it might eat up the 1 terabyte a month. I've only had the Xfinity Essentials for 3 weeks so hard to judge so far. I've tried not to watch TV to much until I can find out for sure if it will take me over the allotment.

It is only me using the devices, one computer and two TV's. I rarely used my cell phone for anything. 

And advice would be greatly appreciated.
