Risks of Using VoIP & Calling Apps on Public Wi-Fi

• Eavesdropping / Packet Sniffing: Attackers can intercept unencrypted or poorly encrypted traffic to listen to calls or read messages.
• Fake / Evil Twin Hotspots: Scammers set up Wi-Fi networks with names very similar to legitimate ones (e.g., “Airport_Free_WiFi” vs “Airport-Free-WiFi”) to steal credentials and data.
• Man-in-the-Middle (MITM) Attacks: Attackers position themselves between you and the internet to intercept login sessions, tokens, or call data.
• Malware & Rogue Certificates: Some public networks attempt to install fake certificates or push malware when you connect.
• Session Hijacking: Stolen cookies or tokens can let attackers access your MyLine account or linked services.

How MyLine Protects You on Public Wi-Fi

MyLine includes several built-in safeguards that make it one of the safer choices for public network usage:

• Full TLS Encryption for Signaling — All call setup, login, and control traffic is encrypted with modern TLS (1.3 supported).
• SRTP for Voice & Media — Actual call audio is encrypted with Secure Real-time Transport Protocol — preventing eavesdropping even if someone captures packets.
• Encrypted App-to-Server Communication — All data between your device and MyLine servers (including messages, balance checks, and settings) uses strong encryption.
• eSIM Cellular Data Fallback — When available, switch to MyLine eSIM data instead of public Wi-Fi — giving you a private, encrypted cellular connection.
• Secure Authentication — Strong session tokens, optional multi-factor authentication (MFA), and no storage of plaintext credentials.

Best Practices: Using MyLine Safely on Public Wi-Fi

1. Prefer MyLine eSIM Data Over Public Wi-Fi
   Whenever possible, turn off Wi-Fi and use your MyLine eSIM for calls, WhatsApp, and browsing. Cellular data is far harder to intercept than open Wi-Fi.
2. Always Use a Reputable VPN (When on Wi-Fi)
   Connect to a trusted, no-logs VPN before opening MyLine or any sensitive app. This encrypts all traffic and hides your activity from the local network.
3. Verify the Wi-Fi Network Name & Certificate
   Double-check the exact network name. If you see a certificate warning when connecting or using MyLine, disconnect immediately.
4. Disable Auto-Connect to Wi-Fi
   Turn off “Auto-join” for unknown networks in your device settings to avoid connecting to rogue hotspots automatically.
5. Enable MyLine MFA (if available)
   Add an extra layer of protection to your MyLine account so stolen Wi-Fi sessions can’t easily lead to account takeover.
6. Avoid Sensitive Actions on Public Wi-Fi
   Don’t top up your account, change passwords, or link new payment methods while connected to open networks — do these on cellular data or trusted home/office Wi-Fi.
7. Keep MyLine & Your Device Updated
   Regular updates patch security vulnerabilities that could be exploited on public networks.
8. Turn Off File Sharing & AirDrop
   Disable any local sharing features while connected to public Wi-Fi.
