During a call I can hear the receiver but he can't hear me

Messagenet Talk uses internet connection (WiFi or 3G) to transport voice and SMS.

If you are experiencing the problem with a WiFi connection, we suggest you to check your network configuration: it may happen that a firewall or some network setting can block the transmission of voice.

If you are experiencing the problem with a 3G connection, please check with your carrier if they have blocked certain applications from connecting through their 3G network: some data plan may not allow using 3G network to trasport voice over internet. In this case unfortunately Messagenet Talk will not be able to bypass your carrier's network blockage.
