Iridium Sat Phone Service Plan Advice?

[USMC2602]

I purchased an Iridium Sat phone primarily for my drop in moose hunt in Alaska 2021, but wouldn't mind being able to throw it in my pack during next month's Montana muley hunt.
Wondering what the most "cost effective" service would be in my situation? Really looking for the cheapest monthly charge with the ability to add minutes when needed. Also any particular providers you've had good results with.
Any advice or recommendations would be appreciated.
