A bit different, as it's mainly for voice - but I made an app 'Murmur : Bluetooth Group Calls' - that lets you hold group voice calls and message via a mesh of Bluetooth LE connections. It's available on Android and iOS. https://apps.apple.com/gb/app/murmur-bluetooth-group-calls/i...

Doesn't really get any downloads, so not sure there's much demand for this - but I use it with some shokz bone conducting headphones for talking to my wife when we're cycling (also for wrangling our two small girls)

Cool technology, but what is the usecase? I can imagine traveling abroad without a sim and using it as described. But is it any better than using the cellular network (when you have access to it)?

I possibly live more remote than you do - but mobile data isn't really a thing (in the UK at least) you can rely on continuously when you're cycling, or visiting the supermarket and you've lost your partner near the cheese aisle...

I mean it is in most of the UK. Maybe not in remote areas of Scotland or Wales.

In most of the supermarkets down here, couple of miles from M25. I mean, outside, so its probably considered third-world country, but no, no need to reduce the argument ad absurdum.

Or 2 metres from the window a mile from Hammersmith. If not for WiFi calling I'd have to leave my phones on the windowsill.
