Call apps (Skype, towers, application, cell phone)

[santosg]

If I have a working internet connection but no talk time available on my smartphone, will a free call app still work on my phone or not? My call time has been used up, but will this affect the app from working on my phone if the internet is still working? I would like to use apps that ive downloaded but many just dont work!!!! Whats wrong with this picture??? What am i doing wrong??? Can someone please shed some light here please?? Thank you.

From that scenario, you could use a wifi calling application but not a cellular connection to make/rcv calls. An example would be Skype just to name one of many.

But, how? Can you be a bit more specific? Thank you.

Keep in mind that the cell phone connection is a whole different system than the Internet connection.
The cell phone has a powerful radio that 2-way talks to nearby cell towers.
Your phone has a different radio for connecting to WiFi networks, then to the Internet. Your household Internet provider may bill you by the amount of data transmitted, and the public ones are usually free (but capped by how fast they work).

If your phone's minutes are used up, you should still be able to make calls, using VOIP apps, (Voice Over Internet Protocol), that connect two phones over the Internet, and will consume your Internet Data plan's minutes as it never connects to the cell towers.
