Can send text and emoticons, but can't send pictures.
I'm new to this app and I'm not a developer.
I'm able to send text, but not pictures. We did occasionally have success with video/voice calling, but sometimes we can't.
We're in what is a big commercial private network, that is fairly unstable. One issue I have is that we share one public IP, which means we can't redirect a port to more than one subscriber inside the network.
It's the same issue with several phones.
We don't have problems with Bittorrent or any other program accessing the Internet, except for losing Internet connection once in a while.
