I find your lack of effort "a little disheartening" as you say. It's like you don't want to believe it's cheap and easy to get a decent new phone for very little.
I went to the trouble of doing what you were too lazy to do. I don't have time to do more pointless googling but Verizon prepaid sells a no contract $55 smartphone today. You can likely get better deals if you shop around at all, or are in a cheaper market than the USA. I'm not going to engage with you further, do your own work. https://www.verizon.com/smartphones/orbic-maui-prepaid/?cmp=...
The cheapest phone in India with an HD display comes in at around 25% higher than what Jio phone will sell for (if the $50 turns out to be true).
Disclosure: I did work with Jio (as a consultant) on software for their older JioPhone, running a version of Firefox OS. It sold about 70 million units.
The 300m people Jio is hoping to migrate from 2G to 4G with this phone will now be able to use essential apps such as those needed for Covid vaccination registration, job searches and digital payments. Hence this is hugely empowering.
I find your comment a little disheartening, sorry. You could buy on a black friday sale, or eBay - but so what? The target segment for this phone makes less than $300 a month.
