Not necessarily. Advertising for dumbphones can be about more than just increasing direct sales and earnings. Here's a breakdown of the goals for dumbphone advertising:

• Maintaining market share: Dumbphones still have a niche market, especially for those who prioritize long battery life, durability, or a simpler user experience. Advertising reminds this existing customer base that these phones are still available.
• Reaching a specific audience: There are people who may not need or want a smartphone, For example, children, older adults, or those working in specific industries might be better suited for a dumbphone. Ads can target these demographics.
• Building brand awareness: Even if someone isn't interested in a dumbphone now, seeing ads can keep the brand in mind for the future. This could be relevant if they need a backup phone or a simpler device for a specific purpose.
• Promoting specific features: Dumbphones can still offer some desirable features like long battery life, physical keyboards, or strong radios. Ads can highlight these aspects to attract interested buyers.

While some added sales are always a benefit, dumbphone advertising often focuses on staying relevant within a specific market and reaching a target audience who values the unique features these phones offer.
