im looking at the app ping chat and i was wondering about this. the website here Ping Features on the site it says :: There is no concept of signing in or signing out in PingChat!, unlike other instant messaging platforms. Once you install PingChat! and register your PingChat! ID, you will be always be online. This is great because you don't have to wait for your contacts to sign in to be able to chat with them. so does this mean that if you will always be online as it says, if you use it through wifi, and then turn wifi off and end the app, than if your still online would it cost.
