🤯. 12 years after iPhone debut and some are still new to smartphones.
Keep in mind that regardless if it is 12 yrs after iPhone debut or 50 yrs after iPhone debut, there will ALWAYS be those who will be new to smartphones. For example, someone getting old enough to get their first phone(if it is a smartphone) will be new to smartphones. Until phones are built in to the human body, there will always be those who will be "new" to smartphones.
Additionally, simply because someone has a smartphone does not mean they know or more likely care about how "data" works. Someone who has had a smartphone for years but has recently moved to their own account and is now financially responsible for their own data could likely be asking the same type of question.
