I live in a rural part of Indiana and Verizon Wireless is my ONLY option for internet connection, except satellite dish, which has it's own set of problems. I pay over $200/month for 10 GB data and two "smart phones" and use every bit of it most months. Last month when I used over 90% of my plan data, Verizon texted me to add 5 more GB free. I phoned to verify the offer and it was legitimate. No extra cost for permanent 15 GB data each month. Maybe they felt guilty for charging me $2500/year?
A typical movie will eat up 2 to 3 GB of data, I am told.
We sometimes use RedBox while on the road.
