Prepaid unlimited, family & custom phone plans on Verizon or T-mobile| US Mobile $25/line w/ 3+ Lines

any1 has any experience on this mvno? uses Verizon or tmobile AND most notably free 10GB LTE DATA Roaming in multiple countries. better than Google fi
3+ lines at $25/line all-in and free hbo max/netflix/disney/apple tv+/pandora, etc. pick 2 with 4 lines
seems great deal at $75/mo all-in for 3 lines and free hbo/netflix. cheapest for verizon
Any reviews?
they may throttle after 75GB on verizon, 50GB on tmobile
