For device and cellular plan shoppers who do not qualify for Lifeline (see Lifeline’s eligibility criteria above), the best option for low-cost plans and devices is usually a very limited prepaid plan with an off-brand flip or smartphone. These can be found in most grocery and department stores. Large service providers may also offer prepaid plans, though their available low-cost devices may be more costly than the off-brand devices you’ll find at large retail stores.
