One of (many) benefits of XMPP (Jabber) is that you can use it without a cellular carrier. It is like email in that regard (but XMPP is more for Instant Messaging). Of course, both of those are protocols and not platforms.
You still need some Internet connection, but Wi-Fi is available in many places nowadays. There have been more than a few times I was traveling and did not have cellular service, but I was still able to communicate via XMPP (after connecting to Wi-Fi).
For voice there is VOIP, you would need to set something up like your own telephony server, but all the pieces are there and available in F/LOSS. Even video calling.
Again, protocols and not platforms. Seeing a pattern here?
If you are talking about not even needing Internet, well you better start attending your local HAM club and start learning about radio propagation...
As far as consumer devices from PINE64, maybe the Lora stuff they are working on (announced in blog) might be up your alley. Now, Lora is a protocol, but unfortunately a proprietary one, which has me scratching my head why they have chosen it over open alternatives.

For the most Linux-y experience on your Linux phone, try SXMO!
I am (nominally) the Armbian Maintainer for PineBook Pro (although severely lacking in time these days).
