I stopped using T-Mobile a few months ago. Used to need the Internet while living in a shelter, until I moved into a government funded apartment. I now have TAG Mobile for my phone (free each month w/ 10 gigs of data), and $30/month AT&T 100mb up/down fiber Internet.
Being poor sometimes has advantages.
If you have ANY government assistance program (like SNAP), you qualify for free mobile and reduced cost home Internet.
