Do you think mobile phones will ever get proper peer to peer communication?

It's nothing compared to the fragmentation and lack of cooperation between mobile phone manufacturers and communications app vendors.  Whatsapp can't talk to facetime can't talk to zoom can't talk to MS teams cant talk to Google meet can't talk to Google hangouts can't talk to Google chat can't talk to Google voice...

The telco SIM system is way worse because it is is region locked. If you step off a plane in another first world country without planning weeks ahead and purchasing a regional SIM or roaming plan, you will literally have no service, not even text. On my last trip I had to carry two physical phones and switch from one to the other when the plane landed. That is completely insane.

I have an iPhone and "normal" service with one of the major United States network operators: I can travel to any major country in Europe and Asia and my phone works without having to change SIMs, notify the carrier in advance, etc.  Yes, I have to pay a (frankly, pretty reasonable) per-day charge, but I've never not had service in a "first world" country.

Maybe a business issue rather than a technical issue?

Phones can link into Meshtastic using Bluetooth and Meshtastic can provide secure local communications.  Now we just need a phone which support LoRa directly.

I don't think it's practical for the way phones are used these days, because you need long distance calling and routing a call through possibly hundreds of other phones will always be less reliable and have greater latency than going through cell towers.

No problem just buy a satellite phone and buy a SIM card for the Inmarsat network. The monthly plans are not exactly cheep but you can use it to make phone calls and enjoy a 64kbit/s internet connection in every country in the world. Heck it even works in international waters in the middle of the pacific ocean.

So far every country i visited in Europe my regular home cell provider SIM card worked fine. The only problem was that places outside the EU are not covered under the EU telecommunication laws, and so they make their roaming services insanely expensive (like literally 100x the price). So if you plan to make significant use of the cell network there it is a good idea to buy a local SIM card, but you are not forced to do it, you can still just eat the expensive fees and use your existing home SIM.

How would you expect a P2P phone system to solve any of this? Do you expect your phone call to hop from phone to phone across an entire continent or something?
