Passive income: NO

Selling phone wallpapers can potentially lead to passive income, but the likelihood largely depends on factors like niche selection, marketing strategies, and automation tools. Setting up an online store and utilizing platforms like Etsy or Shopify can help automate sales processes. However, achieving true passive income where minimal ongoing effort is required is rare and usually seen as an outlier rather than the norm. While some individuals may share success stories online, many sellers need to consistently create new designs, manage customer inquiries, and stay updated with trends to maintain sales. It's essential to note that passive income from selling phone wallpapers typically requires continuous effort to grow and sustain the business.
