You Can Get a $50 Phone From Amazon, If You Don’t Mind the Ads - Bloomberg

From the Amazon product description: dual SIM and unlocked (but check the fine print, e.g., no Sprint or Verizon Wireless service, and only partial 4G LTE data on AT&T and T-Mobile)

"While America’s wireless carriers are phasing out subsidies for high-end phones, Amazon is tacking the other way. Starting last month, the retailer began offering Prime subscribers the Blu for $50 if buyers are willing to put up with ads on their lock screens. (It’s also selling a similar Motorola phone from Lenovo for $200, or $150 with ads.) Samuel Ohev-Zion, Blu’s chief executive officer, isn’t coy about who his audience is. “They’re not able to afford an iPhone,” he says.
The Blu R1 HD, which began shipping last month, has a just-OK battery and cameras and speakers that aren’t exactly cutting-edge. The 1 gigabyte of RAM and 8GB of storage space on the cheapest version of the R1 HD is a little anemic, but both can be doubled for an extra $10, putting them in line with the cheapest ($649) iPhone 6S. For $100 or less, it’s a better deal than most prepaid smartphones."
