It's important to understand that the internet is a fundamental component of the Bitcoin network and is required for transactions to be processed and confirmed. Any claim of conducting Bitcoin transactions without internet connectivity is likely to be misleading or fraudulent.

as far as I understand it, yes. An Internet connection is needed in order for a transaction to be processed. that being said, there is an article that talked about an alternate way of sending Bitcoin using radio waves, satellite or SMS. it was an interesting article to read(article). if you are curious about these alternate methods, there are existing articles that are focused on talking about each of those ways.
