When Bush Jr was president I was absolutely confounded by how people could support him. Then I got older and could see how people don't know how to do basic research.
With Trump, you just watch a speech or see his social media posts. It should be immediately apparent to anyone that he's a spineless, lying, idiot.
Trying to comprehend how such a loser remains in power hurts my brain.
I've used both. US mobile is much cheaper. It's also monthly or annual. $220 for a year of unlimited data with hotspot is the best deal I've found. If you don't need more than a couple gigs of data, you can go as cheap as $10/mo.
I won't swear by US mobile, but so far, no regrets from me.
