When we talk about budget-friendly, affordable, or even ultra-low-cost smartphones, we usually mean devices available for under $400, $300, or $200 a pop with no carrier strings attached.
But when it comes to prepaid products you can buy from “minor” operators like Boost Mobile, Metro by T-Mobile, or Cricket Wireless, it’s not unusual to be charged less than $100, especially if you’re willing to port in an existing phone number from a different carrier.
