Roaming Borders Checklist de viaje app para Android
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.
