Q40:After using WorldCard Mobile for a period of time, WorldCard Mobile closed inexplicably. What can I do?

Answer:

This is the memory problem of the system. Because iPhone cannot release memory and the applications you run before may still occupy the memory. Therefore WorldCard Mobile does not have enough memory to run all functions. You can press the power of iPhone for 3 seconds. A slide bar will appear on the screen, please slide the bar to shut iPhone down, and then press the power to turn it on.
