Current now, i got Wi-Fi connection, the Internet call was selected with my VoIP account.. then i take out the SIM.
I'd tried to make call from contact number, press call button but the call function is using the phone function and the pop-up say "Networ service is not available. Try again later".
So, pls enlighten me how can I get this VoIP call using Wi-Fi setting.
FYI, I can use Voip by Fring software.
