I have AT&T uverse internet service. My box thingy is a 503INV black box with green lights.. as you can see I'm a real tech savy grandma..

I use my laptop with wi-fi.

I want to know how much "data" I use monthly. I was told to get "data/internet" software for my laptop. also, my box should be able to tell me via the "software" that should be installed on my laptop. ??? Have no idea what any of this means.

Help...

I want to know as I will be doing more traveling and need to know what type of internet service I need but I have to know my usage to give me info to see what options I have.

Thanks for the imput...
