Can you please tell me what data plan/how much data is required per month to run the jobber app?

We have been using Jobber for 5 years but have never used the timesheet component and now would like to move the teams onto using the app and entering time sheets on the app. They can then also see the details of their job, receive their schedule and any changes, enter expenses... etc. I am trying to find out what data usage is likely to be so that I can cost out the cost of the move to ipads and data instead of paper.
