Roaming Borders vs TLSFragment
Side-by-side comparison of two open source alternatives
Roaming Borders
Why this app? When you travel near country borders, your phone may automatically connect to a stronger cell tower across the border—even if you never left your country. This can quickly result in costly roaming fees. Manually toggling roaming is inconvenient and easy to forget.Roaming Borders automates the guardrails so you don’t have to. What it does Block roaming when you don’t want it: Select allowed countries; if your device connects outside that list, data traffic is blocked. Avoid surprise charges: Prevent accidental cross-border roaming near national frontiers. Simple presets or full control: Choose ready-made country presets or build your own list for upcoming trips. On-device only: Uses Android’s VpnService as a local firewall. No tunneling to servers. How it works Roaming Borders runs a lightweight, on-device VPN that filters traffic based on your current country. When your current country is not in your allow-list → block data traffic system-wide. When your current country is allowed → allow traffic as normal. When connected to Wi-Fi, the guard pauses automatically and resumes once Wi-Fi disconnects. Note on reboot: After restarting your phone, the guard re-enables after a short delay. To be extra safe, enable Airplane mode before restarting.
TLSFragment
Currently, Android only has a proxy, which cannot be used alone. You have the following options. 1. **Recommended**: Use Kiwi Browser, which supports extensions, and install Proxy SwitchOmega for use. (OmegaOptions.bak is available under the browser) 2. Use FREE Browser on F-Droid 3. Use SocksTun on F-Droid, fill in 127.0.0.1 for Address, 2500 for Port, check UDP relay over TCP, check the proxy application in APPS, and do not select Global, otherwise the tlsp traffic will be in an endless loop 4. Set up a proxy on the Android system. Reference: https://github.com/maoist2009/AndroifFrag/issues/1 (adb is also possible) ## User Feedback Group (Matrix only at present) github discussions and issues are availabe too. [matrix space](https://matrix.to/#/#tlsp_public:matrix.org) or you may join public groups directly. + better config(such as available ip or mode)： + the tlsp programme itself： + proxy or vpn setting There is a private room. I have been a little lazy in the development of this program recently, mainly for rule maintenance. ## Notes I hope that the second socialist revolution will win soon and this broken wall will be completely smashed. (It is not to say that there can be no censorship of speech in socialism. On the contrary, censorship of speech is necessary to maintain the dictatorship of the proletariat. However, it should be public and gradually expand the participation of the masses) Down with Chinese revisionist imperialism Proletarians of the world, unite!
