Not sure if I am allowed to dish out Firmware dedicated to me in a service request ticket.

to conclude

Yes, it does reset at 48 hours the same, but you can use your data how you like on a given basis in that 48 hour window.

Perhaps trigger the connection off at sometime after COB.

Let me know if you have any issues with the 100 gig one, as I said this is a 50 gig phone one. I know commercial data only's are the same as phone in terms of data, just minus texts and minutes.
