How to Make Calls on Public Wi-Fi Safely
Browser calls are encrypted, so public Wi-Fi is usually fine for ordinary conversations. For anything sensitive, switch to mobile data or add a VPN.
Before you call
Confirm the network name with staff, since fake networks with similar names exist. Keep your browser updated and avoid downloading anything on the same network. Test your microphone first so you aren't fiddling with settings in a crowded room.

During the call
Use earbuds so nearby people can't hear the other side. Avoid reading out passwords, card numbers, or ID details. Who's within earshot is often a bigger risk than the network itself.
When to switch
Move to mobile data if the Wi-Fi is slow, asks for a suspicious login, or the call is sensitive. A reputable VPN adds another layer if you must stay on the network.
Make a call without creating an account
GhostCall lets you start a voice call from your browser with no sign-up and no phone number.

Usually yes for the audio itself, thanks to encryption, as long as you follow the habits above.
Do I need a VPN?
It's optional for casual calls and sensible for sensitive ones.
Why does call quality drop on public Wi-Fi?
Shared networks get congested. Moving closer to the access point or switching to mobile data often fixes it.
