Troubleshooting
No sound / Can't hear the other person
Check that your browser has microphone permission enabled. Try refreshing the page. If on a VPN, try disconnecting it — some VPNs block WebRTC.
Call drops or choppy audio
Switch to a more stable connection if possible. TwinPhone's adaptive audio handles most issues, but very slow connections (under 100kbps) may cause problems. Close other bandwidth-heavy apps.
Number not dialing
Make sure you're using the international format: + followed by country code and number. Drop the leading 0 from local numbers (e.g., Tokyo 03 → +813).
Credits not appearing after payment
Credits usually appear instantly. If delayed, refresh your dashboard. If still missing after 5 minutes, email support@twin-phone.com with your payment confirmation.
