Livinlite / MobileMustHave unlimited ATT mobile data plan?

With the shortage of rural mobile internet options, I’m trying to find a plan for the cottage. This popped up on my internet search but can’t find much further info. Has anybody heard of livinlite dot net found on a mobilemusthave website who are advertising AT&T unlimited internet? https://www.mobilemusthave.com/ATT-Unli ... _p_66.html
