I thought about signing up for the FMCA plan for 25gb on the hotspot but what that does is adds 10gb's to my existing 15gb that I get already on my hotspot for an added $50, I thought that was too much.
This is what I do. I have the Verizon "unlimited plan" on my whole account which gives me 15gb of hotspot data on each of my devices ( I have 4, 2 phones, 1 tablet and a hotpost) for a total of 60gbs each month at the high speed. I do have to switch devices when one reaches its 15gb's kind of a hassle but it works out great for us. I have used up to 40gb in one month and was never throttled. On our plan I pay $40 per line but they have other plans too
