# Do walkie talkie apps work without internet?

Cellular data works. You don't need Wi-Fi.

COPY works over cellular data, so you don't need Wi-Fi. If you have neither, you'll need a different way to communicate.

It looks like a radio. Messages travel over your phone's data connection.

## No bars, but there's Wi-Fi

If you're at a house with terrible cell reception, COPY can use Wi-Fi instead. Each person can use whichever connection is available to them.

On a trail with neither cellular data nor Wi-Fi connected to the internet, COPY won't carry the conversation.

## For nearby phones without internet

Some apps connect nearby phones over a local wireless network.

We haven't tested those, so we can't recommend one. COPY needs Wi-Fi or cellular data.

## Across town works. So does another country.

Your friend can be across town or in another country. Turn to their channel and talk.

They open COPY to listen. An unplayed message waits for up to seven days.

Talking is free on iPhone. [Send a friend an invite](https://getcopy.app/help/invite-a-friend) and you’ll have a channel together.
