Can I use WhatsApp or Skype if I have no cell phone signal?

Question

I'm going hiking this upcoming weekend and I'm worried I wont be able to use my regular text messaging or phone calls because cell signal will be spotty.

Answer 1

Sure, as long as you have a wi-fi signal.

Answer 2

Those are Internet-dependent apps. So if you have no Internet access (Wi-Fi and/or mobile data), then they won't work at all. Did you think that those apps work on magic or something? Not trying to be mean, I'm just curious.
