smoke signals works radio signals works neutrino BIP157 works
But the important question is: if you are in a such remote area that you get only text, I think you will have other more important priorities than syncing a blockchain.
Thanks for your reply. Yes, I realize that anything which can encode information (such as smoke signals) could technically "work," but I would like to know which is the most practical and most likely to be adopted/used.

As I said, if you are in a such remote area that you can't even run a mobile LN node like Breez, Blixt, SBW, Nayuta, Electrum... I don't know why do you want to complicate so much. If you are in a such remote area, you will not have anyway where to spend your bitcoins, not even online. You will be more focused on shelter, water, food, security than... internet and bitcoin.

Again, thank you for your reply.

It is not a thought experiment about a node being in a remote area. To the contrary. It is a thought experiment about where exactly the "edge" of the network even is, whether we can safely push lightning and lightning payments out to the edge.
But I suppose I did not spell it out that way and can understand how you interpreted it.
