simplex-chat VS Signal-Android

For messaging I'm currently on Olvid (E2E with physical key exchange) but since it still use their servers, I'm currently testing SimpleX where I can host my own servers.

Notice how SimpleX (https://simplex.chat/) has no push notifications by default because of this issue.

I've been using SimpleX [0] with a couple of friends recently. It appears to work as advertised.

If you have a mobile phone number, the domestic intelligence agency knows exactly where you are at all times and any LEO (without a warrant) can also find you. In addition, there have been numerous CCC presentations showing how insecure the global (excluding US) and (separately) US carriers are guilty of promiscuous metadata trafficking ($$) and insecure SS7 setups. As a consequence, for low $, you can go to any one of several shady websites and find the last location of almost any phone number (person unique ID) globally. There are additional varying exploitable vulnerabilities depending on the exact combination of {handset x carrier x country} to impersonate them, tap their line, reveal their exact location, and redirect their phone number through a third-party handset or even a PBX. These are more expensive and some capabilities are forbidden for all but a few selective intelligence uses.

Session (Signal fork) doesn't use phone numbers. It's pretty well-designed overall and uses an onion routing approach. It's already a superset of Signal except it doesn't use phone numbers. https://getsession.org

PS: Using regular TOR on home broadband or cloud servers is relatively risky and inefficient. Sybil attacks on it are common. And to network operators and security agencies it gives an easy "flow tag" of your uplink and exit node data traffic as automatically suspicious.

Why not open up a Feature request on https://github.com/simplex-chat/simplex-chat/issues

The fork by johanw666 is most likely not going to keep SMS support, see here and here.

there is already Singal fork with no APK expire whrere you can keep using SMS as long as you want

https://github.com/johanw666/Signal-Android

Just use Johann's fork with SMS support and no APK expiration and don't update it. This would either buy you some months before proper alternative will be introduced or at best work infinitely.

Just use Signal fork with SMS feature and don't update it, this fork should keep working even if Signal tries to force you to update.

I've been looking into this fork and hopefully the dev ends up keeping SMS : https://github.com/johanw666/Signal-Android

Signal Fork by Johanw666 is it safe right? I've been using it for long time
