By 2028, the projected number of smartphone users is approximately how many?

• A. 5.9 billion
• B. 7.86 billion
• C. 6.5 billion
• D. 8.2 billion

Answer: (B)

Smartphone adoption grows with population size and market reach, so by 2028 the number of users is expected to be near the total world population but not exceed it. The projection of about 7.86 billion users fits that idea: it reflects widespread ownership across regions, with only a portion of people still without smartphones due to factors like affordability or age. In other words, you’d expect the user base to be very large—close to, but not past, around 8 billion people worldwide.

The other figures don’t align as well with this trend: 8.2 billion would exceed the total population, and figures around 5.9 or 6.5 billion imply substantially lower penetration than current growth suggests.
