Telegram Calls

• How do I make a call on Telegram?
• Do you have privacy settings for calls?
• Can I see how much data my calls use?
• How do I make calls use less data?
• I see four emoji with each call, what do they mean?

Make Calls

iOS: Open a chat with a friend > tap their name at the top > Call. If you'd like, you can add a "Calls" section to your tab bar from Telegram Settings > Recent Calls.

Android, WP: Open a chat with a friend > tap on "…" > Call. A dedicated "Calls" section can be found in your main menu.

Native macOS: Open a chat with a friend > tap on a call icon near their name at the top.

Telegram Desktop: Open a chat with a friend > tap on the call icon at the top right.

Privacy Settings

You can control who can and can't call you in your Privacy and Security settings.

iOS: Settings > Privacy and Security > Voice Calls > You can choose who can call you.

Android, WP: Settings > Privacy and Security > Calls > You can choose who can call you.

Native macOS: Settings > Privacy and Security > Voice Calls > You can choose who can call you.

Telegram Desktop: Settings > Privacy and Security > Phone Calls Privacy > You can choose who can call you.

Data usage

In our mobile apps, you can track your Network Usage in your Data and Storage settings.

iOS: Settings > Data and Storage > Network Usage > Scroll down to Calls to view Bytes Sent/Received.

Android: Settings > Data and Storage > Mobile Data/Wi-Fi Usage > Scroll down to Calls to view Bytes Sent/Received.

Use less data for calls

Note: If you enable this settings, the quality of calls will be reduced.

If you feel that your calls are taking too much data, then you can choose to reduce data usage.

iOS: Settings > Data and Storage > Use Less Data > "Never/On Mobile Network/Always".

Android: Settings > Data and Storage > Use less data for calls > "Never/On Mobile Network/Always".

Key verification

When a call is initiated, the participating devices exchange encryption keys using the Diffie-Hellman key exchange. After the secure end-to-end connection has been established, you will see four emoji on your screen.

They visualize the encryption key for your call: to make sure that no man-in-the-middle attack can succeed, you and your recipient just need to compare these emoji. If they are the same on your recipient's screen, you can be sure that the call is 100% secure.
