How the fuck they decide what is a burner vs a phone owned by people who don't like getting raped by the likes of AT&T is beyond me.
Edit: Per suggestion below, one option is textverified.com. I have verified this works. You can pay with crypto. As little as 75c
Mint and US Mobile both offer eSIMs. I am not up to date on whether their eSIM offerings fall under any cheap trial offers, though.
Full disclosure, I use Mint for my primary number, 'cause it's cheap, but had no issue grabbing one of the trial SIMs and using it to set up some accounts.
If I order online, i gotta give em my name and address. If it's to be a burner, I'm thinking I should go buy one cash from best buy with a prepaid card. IDK if that will work, though.
