Why Voice & video calls doesn't work in Iran

Voice & video calls is deliberately slowed down in Iran.

International internet returned on 26 May 2026 after an 88-day blackout, but Instagram, X, YouTube, Telegram, Facebook and Signal remain blocked.

Is a VPN legal in Iran? Legal with restrictions. Only licensed VPNs are legal, yet unlicensed VPN use is near-universal. During full shutdowns no VPN can help because there is no international connection to tunnel through.

Step by step with ExpressVPN

  1. Get the VPN before you need it

    Sign up for ExpressVPN and download the app while you still have an open connection, ideally before you arrive in Iran. VPN websites and app-store listings are often blocked there.

  2. Install and sign in

    Install ExpressVPN on the phone or computer where you use Voice & video calls, then sign in.

  3. Switch on its stealth mode

    Open Settings, then Protocol, and keep it on Automatic. ExpressVPN obfuscates every server, and Automatic lets it switch protocols when one gets blocked.

  4. Connect to a nearby server

    Connect to a server in Germany, Netherlands or Switzerland. Voice & video calls works normally in these countries, and nearby servers are faster.

  5. Make a test call

    Start a short call with the VPN connected. If audio cuts out, switch the VPN to a TCP-based protocol and try again: call traffic is the easiest kind for networks to spot.

  6. Leave the VPN on

    Keep ExpressVPN connected while you use Voice & video calls. If you disconnect, the block applies again.

Tip: Keep the VPN on for the whole call. Turning it off mid-call usually drops the call.

If it still doesn't work

  • Try a different server country: Germany, Netherlands or Switzerland.
  • Restart your phone after a failed attempt. Some blocks cache your earlier connection.
  • If Voice & video calls loads but crawls, the VPN is connecting but being spotted. Switch on automatic obfuscation (protocol set to Automatic).
  • Update the VPN app. Providers update their stealth protocols when blocks change.
  • Switch between Wi-Fi and mobile data. Some networks block far more than others.
