Frequently asked questions

What are end-to-end encrypted calls on Fi?

End-to-end encryption is a technology that keeps the content you share private and secure, from one endpoint (such as your phone) to another (such as the phone of the person you are talking to). The content you share will be unreadable if it is intercepted in transit.

Fi offers end-to-end encrypted calls for one-on-one conversations between Android phones on Fi by default, which means eligible phone conversations are protected automatically and only you and the person you're talking to can listen to the contents of your call.

End-to-end encrypted calls require connection to a cellular or Wi-Fi network, and is not available for calls with non-phone devices (such as a computer), group calls with 3 or more participants, forwarded calls to a number not on Fi, or calls made or received in countries where VoIP calling is not supported (Cuba, Iran, North Korea, Russia, South Sudan and Syria). Call details such as phone numbers, call duration, call time, and voicemail are not end-to-end encrypted. To learn more about end-to-end encryption on Fi, visit our Help Center.

Who is eligible for end-to-end encrypted calls and can I disable it?

Android phones on Fi are eligible for end-to-end encrypted calls. We believe your privacy should be the default—if you and the person you are talking to are both using an Android phone on Fi, your conversation will be encrypted automatically. Learn more on our Help Center.

How will I know my calls are end-to-end encrypted?

If your call is protected with end-to-end encryption, you'll see a lock symbol on the screen before your call is connected and during the call. When you place an encrypted call, you'll hear a unique ringing tone before being connected. Learn more on our Help Center.

Does Fi offer end-to-end encrypted text messages?

While Fi does not offer end-to-end encryption for text messages, you can use Messages by Google for more secure chat conversations. Messages automatically upgrades your one-on-one conversations to be end-to-end encrypted when both you and the person you're messaging have Messages and chat features enabled. With end-to-end encryption, no one can read the content of your messages as they travel between your phone and the phone of the person you're messaging. By using Fi and Messages together, you can get a private communications solution for both calls and texts. Learn more about end-to-end encryption in Messages on the Help Center.
