When camping how much civilization or technology should one have access to before it is no longer camping?

Before camping turns into something that is camping like, how much technology or civilization does one have to have with them at their disposal or access too? For instance, if you are still within cell range so you can surf the Web is that still camping? How about if you are so close to civilization that you can walk or take a short drive to a store, market, Walmart, etc. are you still camping? If you are pulling a trailer or in an RV and just hop from park to park, even though you light a campfire, is that still camping? Basically how self-sustaining do you or don’t you need to be to be truly camping?
