⚠️ Please Note

Zoiper is a standalone VoIP softphone and does not include a calling service. You must have a SIP or IAX account with a VoIP provider.
Do not use Zoiper as your default dialer; it may interfere with emergency calls (e.g. 911).
Only download from Google Play — unofficial APKs may be unsafe.
