Questions, answered.
More help lives inside the app under Help, including a way to send us your logs if something goes wrong.
Do I need a SIP account to use VoiZip?
No. VoiZip works as a regular phone app with just your SIM cards. SIP accounts are optional extra lines.
How do I install the APK?
Open the downloaded file from your notifications or the Downloads folder. The first time, Android asks you to allow your browser to install apps: allow it, go back and tap Install.
How do I make VoiZip my phone app?
Open your phone's Settings, go to Apps › Default apps › Phone app and choose VoiZip. The exact names can differ a little between phone brands.
How do I add a SIP account?
In VoiZip, tap the gear to open Settings, then SIP accounts › Add SIP account, and enter the details your provider gave you.
How does VoiZip know which line to use?
When more than one SIM or SIP line can place the call, VoiZip asks you. The side menu shows each line and whether it is ready.
My SIP calls sound bad or drop. What can I do?
SIP calls use your internet, so try Wi-Fi or a stronger mobile data signal. If it keeps happening, open Help › Troubleshooting in the app and share your logs with us.
Your next call, on the right line.
