The usage of my plan depends on my work setting which is constantly changing, It all depends on where I'm working and what I'm doing. I'm suggesting to credit back a percentage of the cost for functions that don't get used.
For instance if I'm at a camp job I will burn through a lot of internet. If I'm traveling a lot I will barely touch my internet plan but I will be calling and text a lot to communicate. because I never know where I'm going to be I need access to all options just in case. In this circumstance it would be nice if a portion of that plan that doesn't get used could be credited back or credited directly to my tab. It would be nice.
