Why does my smartphone wait to call?

[AC Question]

why does my smartphone wait to call.

Sometimes when I dial a number and hit send my phone doesn't make the call until 10, 20 or 30 minutes later. Why and how do I fix it?

That sounds like a serious defect. 30 minutes?? If it's seconds, maybe a signal issue but MINUTES ?!!
