want to get rid of H**^%^net, due to FAP c%^&%. can verizon help?

Been with above mentioned satellite company for several years. The FAP (Fair Access Policy) seems to be getting smaller and smaller as the months go by. We can exceed this without any problems—daily–if we are not careful. Then purgatory for 24 hrs.
I have a pc that was hand made by a local computer company with many usb’s and slots with Windows xp.
We live in the extended service area for verizon with great service for our cell phones.
Could I possibly add a card to my pc and take advantage of this service they have for wireless (mobile) internet service?
The only options where we live is satellite or dial up. Both options stink as far as I’m concerned.
