TxtNet-Browser VS GoodbyeDPI

Hello all,

This is my second year of working on a project[1] with the goal of browsing the web, on an Android smartphone, without reliance on Wi-Fi or mobile data. While this concept might seem aimless, my goal was to provide a way for people in areas with limited, expensive, or censored cellular internet access a way to view the web in a basic format. I finished work on a basic client-server model last year[2], and this year, I implemented a new pseudo-distributed peer-to-peer model that allows any TxtNet Browser user to use their own smartphone to run a background server service that communicates via the user's own primary mobile number. The main advantage to this model over last year's use of the Twilio API is the fact that with an unlimited SMS plan from a consumer carrier, you will likely end up paying significantly less than the amount you would pay for Twilio credits (averaging about ~$0.50 per website). There's a lot going on with the stateless nature of SMS, GSM-7 encoding, and Brotli compression, so please ask any questions you might have!

I've also started up a test server instance running on a +1 country code phone number, so feel free to test out the app with your own smartphone. Like mentioned in the GitHub repo, please be aware that I (necessarily) have access to every phone number and associated request that is sent. Of course, anyone can host their own server instance, and if you would like to share it, feel free to get in touch so I can add the number to the repo! Also, there are likely many bugs still lurking, so feel free to report those.

Right now, it is accessible only through VPN. Even programs like DPI blocker are not helping

As in you cant access those sites (you got redirected to the ISP site)? Try changing your dns (make sure to clear your dns cache too) and try using goodbyedpi. Recently my country start enforcing isp to block piracy sites along with other sites (porn, reddit, etc) but since their method is just to use dpi, i could just use goodbyedpi to bypass it.

Russian internet censorship is very simple. They don't seem to be using DPI to target VPN protocols at all, instead trying to block IPs/subnets of known commercial VPN providers. Blocking IPs, subnets, and domains is the primary operating mode of Roskomnadzor.

There allegedly is DPI, but it only comes into play as an extra measure against things like domain fronting, proxies, and plaintext HTTP. It'd look at the SNI and inject a RST packet to drop the connection. As it does not even try to implement TCP, analyzing each IP packet in isolation, there are various interesting utilities[1] that mess with it by, for example, splitting the TLS ClientHello into two TCP packets in the middle of the domain name.

Also, try this tool, you'll find that unblocks most content for you. Good luck!
