M1 Nighthawk on Tablet plan?

[Rizzader]

Greetings

Recently moved to a place we can only get DSL 18/1 internet. Decided to get a $20 unlimited iPad plan off eBay. Basically they give you An IMEI to use and then you just out the activated sim in your hotspot (in my case an M1 Nighthawk). I would prefer to do it “more legally” by just using an old iPad or iPhone that we have and then tether that connection to the nighthawk, and from there share it with all my devices (I know you can just use hotspot mode on phone or tablet, but that gets deprioritized pretty quick I believe).

Is there a way to do so? Trying to avoid buying all new equipment if possible. Had the nighthawk for a couple years so figure I should put to good use of there is a way.

Thanks in advance!
