Most of them are useless. Some of them without a mobile phone and phone adress unusable. And lot of them does not workig in serval platforms. Very much of them are use a centralized network. And imposible to set up a simple proxy. Asking too much sensitive private data like phone number. A simple good working platform like [Jami](https://jami.net/) will be ideal.
