There is no official government program that provides free iPhone 7 or any other smartphones to citizens. Government programs may offer subsidized or discounted phones to qualifying individuals through specific initiatives, but they typically have eligibility criteria and are limited to particular groups, such as low-income individuals or those participating in certain assistance programs.
If you're looking for a free or subsidized phone, you might want to explore programs like Lifeline Assistance, a federal program in the United States that provides discounted or free cell phone service to eligible low-income individuals.
Keep in mind that availability and programs may have changed since my last update, so I recommend checking with relevant government agencies or authorized service providers for the most up-to-date information on any assistance programs related to mobile phones.
