Persistent silent registration failures especially in Russia (alternate registration/validation flows desperately needed) + Censorship circumvention basically fully suppressed

Bug description

I understand there is a balance to be struck between resilience to spam and various hijack attempts and friendliness to VPNs but at this point of time registering to a Russian number to a VPN is borderline impossible

The userbase most desperately in need of secure comms solution is also being drastically underserved by Signal as a result

As a separate but related issue, censorship circumvention in-built Signal solutions are at this point being reliably detected by russian state censors and suppressed (VLESS+ based VPNs still work and are good at their job, but using VPN massively aggravates the registration problems, likely due to "dirty" IPs)

Signal users in authoritarian countries like russia desperately need

1. better registration flow (this is, dare I say, critical, because at this point I can't even onboard new moderately technical users who know how to use a VLESS VPN, they can get to "internet at large" but not register Signal, because, well, the registration flow stalls or rejects them)

2. better censorship circumvention (alternatively, a closer integration to powerful VLESS+ and similar VPN providers who have a solid track record of breaking out from under technologically powerful authoritarian regimes like russia and china)

No file, test, entry point, device details, version, or debug log is named. Start by reviewing the Android registration and censorship-circumvention flows, then reproduce registration with a Russian number and VPN; done would require an agreed scope and evidence that the selected flow works reliably.
