Which ICT function would be affected if a mobile phone has no internet connection?

Correct answer: Making an online video call

The governing concept is the difference between online and offline ICT functions. An online video call must send and receive audio and video through a network, so it normally depends on an internet connection. Option A is therefore correct. A calculator, a previously saved photograph, and the device clock can generally work without internet because their basic functions and required data are already available on the phone.
